10 Mbps Fiber Offers Future Growth

By: John Shepler

There’s nothing that stifles productivity and raises your blood pressure like too little bandwidth. You wait and wait and wait for websites to load, for the cloud to give you the requested documents, for any sort of collaborative effort. Video breaks up or buffers. VoIP phone calls distort or hang up completely. It’s a miserable existence. What’s more, no amount of processor power or RAM memory will make the problem any better. You simply have to increase your network bandwidth to match the need.

What’s a Good Target Bandwidth?
That’s hard to say. Not to be coy, but how much you need is really determined by what you are doing. There’s also a matter of what quality of bandwidth you are using, but we’ll get to that in a bit.

Classic T1 lines are about pooped out. They still have merit for point of sale terminals, small office telephone & casual Internet use, and rural areas where choices are few. You can stave off obsolescence by bonding T1 lines together to get up to 10 Mbps, but that gets expensive. Once you need more than 10 Mbps, what will you do?

The Fiber Option
We’re headed for an all-fiber world. Seems like it would be a good idea to get on-board sooner rather than later. The beauty of fiber is that it isn’t technically limited… at least not much. With multiple fiber strands and wavelength division multiplexing, you’ll be hard pressed to run a fiber cable out of capacity.

Fiber has other benefits, too. In addition to eliminating the bandwidth ceiling (you can get up to 10 Gbps in most areas and 100 Gbps in some major markets), the new Carrier Ethernet services are highly scalable. Legacy SONET fiber optic services require a unique interface for every service level. The same equipment won’t work for OC-3, OC-12, OC-48, etc.

Ethernet over Fiber is designed differently. It works more like the Ethernet on your LAN. It’s the port capability that sets the upper limit. Everything below that is available and easily changed. For instance, you can start off at 10 Mbps, move up to 100 Mbps and then to 1000 Gbps if you have a Gigabit Ethernet port for your WAN (Wide Area Network) service.

How difficult is it to change bandwidths? Almost trivially easy. Most service providers will do it within hours or days of your phone call. Some are providing browser based control panels so you can adjust your bandwidth up or down as desired. The future may be something like this or an intelligent system that monitors your traffic levels and automatically decides what bandwidth to order up.

Why 10 Mbps is a Good Entry Point
To gain the benefits of fiber, you have to at least get the fiber installed. This is called “lighting” your building. What’s actually being lit are the fiber strands themselves with laser light. If you are in a multi-tenant building, the fact that the building itself is lit almost guarantees that you can get fiber bandwidth service even if you aren’t the one who had the fiber installed.

So, if you’ve run out of juice with your T1 lines, either can’t get or don’t like the way cable broadband performs, and wouldn’t consider satellite because of the limited capacity and huge latency issues, entry level fiber may be a good way to go. Remember, you want to get a foot in the door so you have that ease of upgrade later.

What’s a good number to start with? Unless you are used to high bandwidth WAN connections, a 10 Mbps ethernet over fiber connection is pretty attractive. For one thing, it’s a huge jump from a 1.5 Mbps T1 line to 10 Mbps. Yes, you can keep bonding T1 lines to get the same 10 Mbps, but you’ll pay a lot more than for the same bandwidth over fiber. That’s because copper lines are priced per line. Each line has a limited bandwidth. The bonding process simply combines their capability, but you pay for each and every T1 line.

Isn’t Fiber Really Expensive?
That used to be true when the only fiber in town was the SONET fiber optic service run by the local telephone company. The newer Ethernet over Fiber services are highly competitive and don’t necessarily use telephone company lines. Many carriers are now in a frenzy to be the first to light buildings with their own fiber networks so they can garner all the businesses that are ready to move up to fiber bandwidth.

Here’s an example. T1 lines have come down in cost, but you’ve long been able to get twice the bandwidth or 3 Mbps for the same price using Ethernet over Copper. Now, Ethernet over Fiber can give you 10 Mbps for not a whole lot more money. In fact, if you’ve had the same T1 contract for many years, you may be shocked to find out that you can have fiber for the same monthly cost.

It only gets better as you go up in bandwidth. The lease price per Mbps of Ethernet bandwidth over fiber gets cheaper as you go from 10 to 100 to 1000 Mbps. The price doesn’t jump nearly as much as the bandwidth does. It’s a bit like the kind of volume discounts you are used to getting when you buy just about any product in quantity.

Quality of Bandwidth
There’s bandwidth and there’s bandwidth. T1, SONET and other traditional telecom services are called dedicated, symmetrical bandwidth services. That means you have the line all to yourself and the speed is the same in both the upload and download directions. That’s true for private point to point lines and Dedicated Internet Access.

Ethernet over Copper and Fiber are the same way. It’s your connection to do with as you please and there are no usage limits. You can shove as much traffic down those lines as they’ll take and the price is the same each month.

The beauty of this arrangement is that your bandwidth is rock solid dependable, never varies, and you’ll get the same consistent performance to or from the cloud or whatever you are connected to. Dedicated connections give you low latency, jitter and packet loss for high application performance.

Contrast that with lower cost shared bandwidth arrangements like DSL, Cable broadband, Satellite and Cellular wireless. These almost always have much higher download speeds than upload and your available bandwidth will vary depending on who is sharing the line with you at any given time. Yes, you can get more Mbps for your bandwidth dollar, but it isn’t the same quality of bandwidth. If you are a very heavy user, you may also have to contend with "fair use" limits. Go over and you'll face additional charges, reduced bandwidth or even service cancellation.
.
Do You Need to Start at 10 Mbps?
Certainly not. The reason that 10 Mbps is so popular is that it is replacing lower bandwidth services like T1, and is plenty for smaller operations. Most medium size or larger offices and anybody involved with video production or distribution will want to start at a much higher level.

Fast Ethernet at 100 Mbps is very popular with businesses who are moving to cloud services or have multiple employees working intensively on the Internet. Gigabit Ethernet at 1000 Mbps is really more affordable than you might think and pretty much makes bandwidth issues disappear for many companies. Larger companies are starting to move to 10 Gbps as their bandwidth standard and 100 Gbps is the new “top of the line” WAN bandwidth service.

Remember, what’s really important is that you get an Ethernet port installed that has the growth capacity you’ll be needing. Even if you start at 10 Mbps, you’ll want a 100 Mbps minimum size port for future growth. Some carriers are installing Gigabit Ethernet ports as a matter of course. They know that it won’t be long before you’ll call up wanting it.

Are you ready to ditch the old telecom standard copper bandwidth services for the advantages that Ethernet over Fiber offers? Are you just curious about what’s available and what it costs? It is well worth your while to take a few minutes and do a quick check for fiber optic service in your area. An expert consultant is available to help match the right solution to your particular situation.

Same Budget, More Bandwidth

By: John Shepler

Is your network sluggish? Are slow file transfers, telephone calls breaking up, pauses in audio and video streaming, unpredictable delays in getting a response from cloud services, and slow web page loading getting on your nerves?

Is Bandwidth The Answer?
You may well need more bandwidth. You don’t necessarily need to increase the speed of your internal LAN. It’s more likely that your outside, or WAN, connection just isn’t getting the job done anymore.

How Can You Tell?
It’s a likely problem if you’ve had the same level of service for years, yet your business has grown or you’re using a higher percentage of multimedia content than you used to. Even a decade ago, T1 lines were standard for small and some medium size businesses. At that time consumer broadband speeds were also a few Mbps. Users were happy because email and Web pages were relatively small. Many business applications were things like credit card verification and after-hours inventory updates.

Look what’s happened recently. Emails are huge. Why? Because they often contain photos and other high resolution images. Web pages are more interactive and more visual that they’ve ever been. Many contain embedded video players.

The Cloud In The Room
This is nothing compared with the growth of the cloud. Cloud services offer near infinite capacity, ease of scaling up and down as needed, and no requirement for capital investments or maintenance activities. This has proven an irresistible combination for many businesses. What gets lost in all the excitement are the increased bandwidth requirements.

What’s happened is that all the traffic that used to flow effortlessly through your Fast Ethernet or Gigabit Ethernet Local Area Network now has to be transported up to the cloud and back down. All those packets have to go through a carrier network for hundreds or even thousands of miles. They have to do that with a minimal time delay and at a price you can afford.

Declining Cost per Mbps
Fortunately, WAN bandwidth services have gotten a lot more competitive, lower in cost and available in a wider variety of options during this same period of change. You may not be aware of it if you’ve simply kept renewing your old line contract or paying month to month since it expired. There’s an excellent chance that you can get the bandwidth you need today without having to jack up your budget… if you’re willing to look at alternatives.

New Quotes Needed
The first thing you need to do is get a fresh set of competitive quotes. By competitive, I mean pricing from as many carriers as possible that serve your location. In the heart of metropolitan business districts you’ll have lots of options. Farther out there will be fewer choices, but almost always two or more. This works to your advantage because the more competition there is, the lower the prices for the exact same service. A number of carriers may have entered your marketplace when you weren’t looking.

Expanded Options
You may also have more options for getting the same job done. For instance, Ethernet over Copper runs on the same wires as T1 service. It offers the same highly reliable dedicated and symmetrical bandwidth. But, Ethernet over Copper can give you twice or more bandwidth than the older T1 technology for the same cost. You may also be able to get higher bandwidth levels with the newer Ethernet services.

How About Fiber?
Impossible to get where you are located? Way too costly? Perhaps not anymore. Fiber buildups have quietly accelerated and carriers have expanded their service footprints around the country. Some of this is driven by the cell phone industry that needs fiber bandwidth to their towers to support 4G LTE. Other runs have been built by the Cable industry that needs much higher bandwidth to deliver digital video channels and video on demand.

The bottom line is that all these fiber operators have bandwidth to spare and they are in fierce competition to get buildings “lit” with their network. They want your business a lot more than they did some years ago. It’s not unusual to find several fiber optic services available where there were none the last time you looked.

New Fiber Options
Like copper-based bandwidth, fiber service is also available in two technologies. The legacy service is SONET, with bandwidth levels such as OC-3, OC-12 and OC-48. Ethernet over Fiber is the newer technology and offers highly scalable fiber services in a wide variety of bandwidth options from 10 Mbps on up to 10 Gbps in most areas. Some locations can now get 100 Gbps if needed.

Just like Ethernet over Copper, Ethernet over Fiber has a cost advantage over SONET. It’s not unusual to get twice and much bandwidth or more for the same cost as your old Optical Carrier contract.

How Much More Bandwidth Can You Get Now?
You may feel that you are limited in bandwidth by budget constraints. It’s possible, even likely, that the budget you have now can be worth 2x, 3x or more high performance business bandwidth in today’s market. Don’t wonder if this is the case. Find out now by checking out the range of bandwidth options and competitive pricing for copper and fiber services available at your business location.

What Makes Low Latency Bandwidth Important

Bandwidth is bandwidth, right? What’s really important is how many bits per second you can squeeze down the line, isn’t it? Or is it?

The speed of your connection is one important specification in a bandwidth solution that will meets the needs of your company. Others include availability, packet loss, jitter and latency. Don’t understate the importance of latency in providing a satisfactory WAN service.

What is latency and isn’t it related to bandwidth? In some cases, yes. Bandwidth increases latency when you don’t have enough for the job. If you have a huge file, say a radiology image, that you need to transfer to another location in 10 minutes and it takes 10 hours, you’ll feel the pain. If your VoIP calls are getting derailed by employee internet browsing, you’ll hear the pain. If your video conferencing breaks up so badly that it is unusable, your employee productivity can really be a source of pain.

Latency is the delay between sender and receiver. If you have all the bandwidth your equipment can possibly use, that delay is a function of how fast the packets can get through the line unimpeded. What slows them down is the speed of light in wire and fiber and any delays introduced by routers, switches and amplifiers along the way.

So, how is it possible to have plenty of bandwidth but too much latency? The perfect example is two-way satellite transmissions. You’ve no doubt noticed that on-location live TV reports seem to have a delay that prevents normal two-way conversations. The anchor and the reporter have to each pause before talking or they’ll talk over each other. That’s latency. Most of it is caused by the simple fact that the geostationary satellite relaying the signal is located about 22,000 miles overhead. Even in a vacuum it takes light and radio waves a millisecond for each 186 miles of distance or a full second for each 186,000 miles. This results in a minimum delay of a quarter-second for a one-way transmission or half a second for a round trip.

Is there a technical way to reduce this latency? Nope. As long as we use electromagnetic waves we’re stuck with Einstein’s speed limit. If you want lower latency, you need to use shorter paths.

One way that carriers are reducing latency is by establishing point to point connections that run in as straight a line as possible. This can mean new fiber installations with minimal length between cities. It also means removing as much electronics from the path as possible. Each box adds a little latency as the signals are converted from light to voltage to light again. Of course, bandwidth has to be high enough that it appears to be transparent to the application.

An extreme example of lower latency requirements is high speed financial trading. It’s computers making trade decisions and placing the orders far faster than a human broker possibly could. Half a second delay is eternity to such systems. Every millisecond counts when you are issuing hundreds or thousands of buy/sell orders every second. Even an optimized fiber optic link from out of state or across national borders may have too much latency. The optimized solution is to move your computers into the same data center as the trading floors. This gets the delay problem from milliseconds down to microseconds and nanoseconds.

You may not need such highly optimized latency reduction solutions for your business. However, you should be aware that cloud services can become latency limited. Any signal delay through your own company LAN is likely unnoticeable. Stretch that connection out a thousand miles or two over the Internet and you may experience noticeable response delays in interacting with your applications. If you can’t live with the performance of the public Internet, you need a latency optimized bandwidth solution.

Big fiber optic carriers like Zayo, MegaPath and XO communications offer high bandwidth low latency private line connections that can improve the performance of your cloud based applications. You’ll also need this for high quality VoIP telephony and video conferencing. Be sure to investigate the impact of latency on your SIP Trunks and multi-location networking through MPLS. Low latency solutions are available for just about every need.

T1 or Better Internet Service

Have you been running “business” grade DSL or Cable broadband and find yourself dissatisfied with the results? Let’s take a look at why that may be and what the options are for higher performance business broadband connections.

First of all, there’s nothing inherently bad about DSL and Cable Internet services. Millions of people are quite happy with the performance of their services, especially for the price they pay. Therein lies the dilemma. Companies salivate at the low cost of these broadband options but are disappointed when the telecom-grade performance isn’t there. The more you think that broadband-is-broadband, the more likely you are to think that it’s all a vast conspiracy to deny you the performance that the technology is capable of.

The truth is that bandwidth is a scarce resource. Like electricity, water, gasoline and other commodities, pricing is set by the cost of acquisition and the forces of supply and demand. Where does broadband come from? The Internet isn’t one big pipe somewhere. It’s a collection of thousands upon thousands of networks. These days, most of those networks have fiber optic cores. If you’ve ever watched a utility crew slowly trenching conduit and big rolls of fiber cable underground, you can understand why there is considerable investment in metropolitan and national fiber networks.

We get lots of inquiries from residential users and home office businesses who think that business broadband services like T1, DS3 or Ethernet over Copper are going to be priced incrementally higher than the consumer broadband they have now. It always comes as a shock for them to see the quotes at 10x or more what they expect to pay. There is no gouging involved. Business telecom services are priced lower today than they’ve been in recent memory and an order of magnitude below what they were when most Internet access service was through dial-up modems. You just aren’t going to get dedicated access connections with consumer grade pricing.

What’s the difference if the Internet is the Internet at its core? There’s no difference between the price that businesses pay for a high performance Internet connection and what your Internet Service Provider (ISP) pays. It’s exactly the same line service. The problem is that nobody but businesses who generate revenue through their Internet connection can afford the cost of this service.

So, here’s what happens. The ISP buys their bandwidth at wholesale rates at the going price for 1 Gbps, 10 Gbps or more. Then they divvy up that bandwidth among hundreds or thousands of their customers. Each customer pays a small amount, say $20 to $60 a month, for their slice of the bandwidth pie. All together, the revenue collected from all those subscribers more than pays for the cost of the ISP’s Internet connection.

That’s right. As a consumer you don’t have an assigned direct pipe to the Internet. What you are doing is sharing a pool of bandwidth provided by your ISP. How fast your service runs depends on how many of your neighbors are in the pool at the same time. If every teenager in the neighborhood is streaming vampire flicks in high def, your line will slow to a crawl. In the wee hours of the night, you may be zipping along at high speed. There will be a maximum you can’t exceed even if nobody else is on. The ISP limits your speed to the service tier you are paying for. But... there’s no lower limit. You could be getting dial-up speeds if everyone absolutely, positively has to be online at once. The reason most customers remain satisfied is that only some customers are actually sitting at their computers at any given time. Anyone not home or doing something offline is effectively donating their share of bandwidth to their neighbors.

Businesses struggle with this kind of service. They all tend to work the same business hours, so every business is a heavy user for 8 hours or so a day and very little after hours. You can’t have your activities come to a halt because the company across the street is hogging all the bandwidth. This is why businesses who don’t like the performance of shared bandwidth services go with dedicated bandwidth. Dedicated bandwidth means that you are assigned a certain guaranteed line speed that doesn’t vary. If you buy 10 Mbps, you’ve got 10 Mbps all day every day whether you use it or not. It doesn’t go into any pool at night. It just sits there waiting for someone to come to work and download files.

You pay higher rates for dedicated line services but you gain important benefits. First, that bandwidth is always available. Second, it is the same bandwidth in both the upload and download directions. Consumer services and business services based on the consumer model have much higher download than upload speeds. That matches the way most personal users access the Internet. However, if you are running a server or upload large files a lot of the time, you’ll run out of bandwidth more often than not.

The third difference involves Service Level Agreements or SLAs. These are guarantees by the ISP as to how quickly they’ll hop to it and repair an outage and what parameters like bandwidth, latency and jitter you can depend on. Don’t know about these? They’re unheard of in consumer circles. Unless you have an SLA, you are dependent on the good intentions of your ISP. They all mean well, but as their ads say, “you get up to so many Mbps of bandwidth.” That means you can’t get more but you can surely get less.

What dedicated Internet services are available for business? These include T1 lines at 1.5 Mbps, bonded T1 from 3 to 12 Mbps, Ethernet over Copper (EoC) from 2 to 45 Mbps, DS3 at 45 Mbps and fiber optic services up to 10 Gbps. The higher your bandwidth, the lower your cost per Mbps but the higher your payments each month. In case you are thinking that you might pony up for one of these in your home office, forget it. It’s rare that any telecom providers will install dedicated services to a residence. You need your own business address.

Do you have such a business address and a burning desire for more dependable and higher performing Internet access? If so, then check prices and availability for dedicated business Internet solutions in your area.

Private Networking With Wavelength Services

There comes a time in the growth of a company when standard telecom services just won’t get it done anymore. This is when the IT department starts contemplating buying or renting dark fiber to get the bandwidth, latency and control they need. There’s another alternative that should be considered, however. That’s managed wavelength services.

What’s a wavelength? It’s one color or lambda on a fiber optic strand. That’s right, fiber optic lines have more than one light beam running through them. Each color represents a different wavelength or frequency of laser light. Because they are different colors, these light beams will mix within the optical fiber strand but one will not interfere with another. It’s like they are completely different pairs of wires in a copper bundle or channels on a cable system.

Why have multiple wavelengths? It’s a matter of efficiency. The cost of the equipment to transmit and receive multiple lambdas is far less than the cost to trench or fly hundreds or thousands of miles of fiber optic cable. Each cable has multiple strands. Each strand has multiple wavelengths. Because of this, each fiber installation has massive bandwidth capability available for commercial use.

The technology that makes wavelengths possible is called DWDM or Dense Wavelength Division Multiplexing. The “dense” designation means that many wavelengths are loaded onto the fiber with close spacing between them. DWDM terminal equipment must have precise and stable control of the grid of light wavelengths on the fiber. There is an ITU (International Telecommunications Union) standard for this so that equipment is common for the industry. There can be as many as 160 channels or wavelengths, all in the infrared C and L bands, on each fiber strand.

What carriers who own fiber assets are doing is offering entire wavelengths for lease to companies that need high levels of bandwidth. Integra Telecom is a good example of a company offering wavelength services on their metropolitan and long haul fiber optic network. One of the nice features of wavelengths is that you can pick your protocol. Integra offers traditional SONET Interface options of 2.5 Gbps and 10 Gbps. You can also get Ethernet Interface options of 1 GigE and 10 GigE.

What Integra is offering is called managed wavelength services. That differs from dark fiber, where you are responsible for all the terminal equipment on each end of the fiber, or unmanaged wavelengths where the carrier simply feeds a wavelength with the signals and perhaps interface modules that you supply. A managed solution means that Integra is responsible for providing the terminal equipment and monitoring the network 24/7 with surveillance and network alarms from their Network Operations Center (NOC).

What you get is a highly reliable, high bandwidth, low latency point to point optical wavelength service for long haul or metropolitan connections. Integra operates a 5,000 mile high speed long haul network with metro services in many major cities of the Western United States and connections to Chicago, New York City, Ashburn, VA, and Dallas. Within the 35 markets across 11 Western states, they operate a 3,000 mile metro access network that includes more than 1900 fiber-fed buildings. If your business is located in Arizona, California, Colorado, Idaho, Minnesota, Montana, Nevada, North Dakota, Oregon, Utah or Washington, you can benefit from the Integra best-in-class fiber optic network, including wavelength services.

What types of businesses are ideal for wavelength services? Companies needing business continuity and disaster recovery solutions, Ethernet transport and optical storage connectivity or data storage connectivity. If you have more than one data center, chances are you need the “big pipes” that wavelengths can provide.

Can your business do better using wavelengths than what you have now for telecom services? Get competitive quotes for managed wavelength services from Integra and other high performance competitive carriers to see for yourself.

How To Deal With Sudden Massive Bandwidth Demands

You’ve been cruising along with fairly stable but slowly increasing network bandwidth demands for years. Then, one day, you are faced with an “out of the blue” requirement to crank up your WAN bandwidth by a factor of 10x or 100x. How did that happen and what can you possibly do to deal with this kind of uncertainty?

It would be strange, indeed, if everybody in the company suddenly decided to start downloading HD movies on the sly. Would it blow your bandwidth allocation? You bet. Does it make any sense? No, of course not. Bandwidth demand doesn’t suddenly mushroom for no reason at all. If you get caught unable to support the need, it’s likely that there is a logical reason and one that makes a lot of sense in retrospect. The question is should you be able to see this coming in time to plan for it?

Sometimes you can’t help but get caught off guard. At a large company where I was working I got an email message with a curious attachment. When I opened it, there was a short video animation of a dancing baby. Not having seen this before, I watched it a few times and sent it on to some colleagues. Turns out that this was an early example of viral video. Everybody in the company was getting this video and passing it on to everybody else.

The IT department was flummoxed. All of a sudden they were running out of disk space. It took a day or two for them to figure out that all of our mail boxes were full of separate copies of the dancing baby video. They were multiplying faster than baby rabbits. Soon a missive came out from IT management demanding that we stop sending this thing around and delete the copies we already had. Crisis averted. Gigantic new disk drive order cancelled.

Today we grab everything off the Internet. Instead of getting a file in our email, it’s a Web link. You probably won’t be filling up the storage drive farm anymore, but any content brought down to the screen is going to have to traverse the WAN. It doesn’t take much of a viral anything to clog up a dedicated Internet connection if the file is big enough and enough people want it simultaneously.

Here’s a more recent example of where IT departments are getting caught short. C-level management gets a case of cloud fever when they see the potential cost savings and insist on moving every application possible to the cloud as fast as possible. In the mad scramble that ensues, the local data center goes dark while the same apps light up at a remote cloud provider. With nearly infinite CPU cycles and GB of storage on demand, everyone expects that the days of bottlenecks are over and that every process will just scream. Shock, horror, and disappointment permeate the office when users discover that formerly snappy responses from the system have gotten sluggish.

How can this possibly happen? Adjusting performance at the cloud doesn’t seem to make any difference. What got forgotten is that all that traffic that ran smoothly on the LAN all of a sudden transferred to the WAN. The line capacity is too small and the latency is too great. Whoever had the bright idea of saving a fortune by accessing the cloud via the Internet is finding out that network neutrality favors Netflix viewers as much as Salesforce.com users, as everyone’s packets take their turn on the Information Superhighway.

This scenario can be avoided with carefully planning and enough lead time to get the right bandwidth resources in place. That can be a challenge when bandwidth provisioning time is the long pole in the tent. You can hedge against future upsets by installing connections that have easier scaling than traditional telecom services. Carrier Ethernet is just such a service. Install a 1 GB port but only commit to 250 Mbps of service right now. When, out of the blue, some VP gets every employee signed up for an online video training course on the latest trendy productivity or quality initiative, at least you can grab the phone and tell your provider to crank up the bandwidth immediately.

You may also be served better by contracting with an MPLS network provider instead of running your own private network of point to point dedicated lines. It’s a major reconstruction effort to upgrade bandwidth on all those lines, especially if you have to go from copper to fiber. Your MPLS provider may be able to give you higher committed rates quickly or allow you to burst to handle unexpected peaks. Best to discuss these possiblities before signing a service contract.

It’s always possible to get deluged with a difficult or impossible to foresee spike in resource demand, including bandwidth. Know that there are services available now that make scaling BW up and down a much easier and quicker process than traditional approaches. Do a little planning now and see what’s available in Carrier Ethernet and MPLS Network services designed for rapid scalability.

Level 3 Vyvx Connects The Super Bowl

While you are busy dipping chips in salsa, screaming at the refs, cheering the plays and rolling on the floor laughing at the commercials, there is one thing you won’t have to think about on Super Bowl Sunday. That’s how the broadcast is getting from there to you. It’s not magic. It’s a carefully engineered service called Level 3 Vyvx VenueNet+

VenueNet+ is a bundled service for special event broadcasters. It’s already installed in every major-league stadium in the United States. That includes Lucas Oil Stadium in Indianapolis. The fiber optic network is lit, the termination equipment installed, and everything is managed by dedicated Vyvx staff.

So, what’s Vyvx and why would you want to order VenueNet+ service? If you’ve ever been involved in a broadcast “remote”, radio or TV, you know that it can be a hit or miss proposition. You need to bring your own transmitter truck and hope you can get the antenna over any obstacles between you and the station or skyward to the “bird.” Otherwise, you need to install a permanent antenna or contract with the phone company for line service (radio) to get the broadcast out of where you are and to the studio intact.

In the age of HD television, this gets even dicier. There is massive bandwidth involved in providing a clean signal that can display high speed action without turning the picture into pixel mush. Can you afford glitches and maybe an all-out outage on game day? Ha! Last year’s Super Bowl was viewed by more than 110 million people, few of whom are in a mood to be patient with technical issues. With multi-million dollar budgets involved in giving you 30 second commercials of clever animal antics that you’ll talk about for weeks, can you afford even a second’s dead air? Nope. Whatever you lose you’ll never get back. There are no re-dos on the Super Bowl.

This is were Level 3 steps in to make life easy. Forget trying to raise an antenna mast or get a leased line connected. The Level 3 fiber network is already in-place at the venue and ready to transport your streaming video. The fiber network has been set up to transport high-definition video optimized for sports events. Vyvx supports HD-SDI, SD-SDI, DVB-ASI and MPEG2/4 and JPEG 2000 encoding. Some venues even support uncompressed HD video. In addition to video encoding and transport, VenueNet+ also provides high speed Internet and telephone service.

The VenueNet+ panel connects to a Level 3 Gateway that gives your video access to the Level 3 MPLS video and data network cloud that can deliver HD video with more than three times the bandwidth currently available by satellite. The fiber network connects to Level 3’s television operation center, broadcast networks, teleports to international and cruise ship destinations, and Level 3 CDN (Content Delivery Network) streaming. Once you hand the raw video to Level 3, they get it where it needs to go, properly encoded.

Level 3 has been delivering the Super Bowl for nearly 25 years. It’s also carries the pre-game and post-game feeds to NFL operations centers in Mt. Laurel, N.J., Culver City, California and NFL Network master control facilities in Atlanta.

The Super Bowl is certainly a showcase for the quality and reliability that Level 3 Vyvx video services can provide. It’s perhaps the best advertising they can have to demonstrate the capability of fiber optic video transport. Even if you are not involved in the Super Bowl or anything of that magnitude, Vyvx can make your life easier for video transport from stadiums and event venues. They’ll get your video to from here to there with the highest quality and least fuss.

The Next Decade of Bandwidth - Part V

Wireless is the bandwidth service that gets most of the press these days, but there are big developments afoot in the wired world as well. We’ll wrap up our look into the next decade of bandwidth with what’s going on with copper and fiber optic services.

It’s no surprise that fiber optic networks are expanding. Some of this expansion is prompted by American Reinvestment and Recovery Act that appropriated $7.2 billion to expand broadband access across the country. Rural areas that have been largely ignored by commercial interests are especially targeted. With funds available for middle-mile fiber runs, competitive carriers are taking advantage of the opportunity to expand their networks.

While fiber is being trenched through the countryside to provide broadband delivery to Wireless Internet Service Providers (WISPs) that serve sparsely populated areas, even more fiber is being routed through metropolitan areas to hookup businesses of all sizes. Government incentives aren’t needed here. Businesses hungry for increased bandwidth either foot the bill for hookups to metropolitan fiber networks or commit to service levels that justify carriers to “light” their buildings for fiber service.

Why the interest in fiber optic connections? It’s not just mobile bandwidth that’s straining at the limits. T1 lines may have been all the bandwidth a small or even medium size business needed to handle email, general web browsing and communication with its website servers hosted elsewhere. Now, 1.5 Mbps seems a bit quaint and inadequate for all the smallest operations. What drives business now is cloud connections, Software as a Service, video conferencing, hosted VoIP and other bandwidth demanding applications.

The transition from 3G to 4G wireless also means that cellular carriers themselves are strained for fast enough backhaul connections. T1 lines works great to connect towers that handled voice calls. When users expect 10 or 15 Mbps of broadband service, fiber optics look like the ideal solution. The cost of construction, once a show stopper, becomes another part of the upgrade investment that’s paid once and offers almost unlimited upgrades for future needs.

Cloud computing is a major attraction for many businesses who find that pay-as-you-go is much easier to justify than requisitions for million dollar data center improvements. No need for racks and racks of servers, the environmentally controlled building to house them, the backup power generators, or the round-the-clock technical staff to keep everything running smoothly. Outsourcing that to a cloud service provider gets rid of those headaches, but adds a new one. How to you connect to the cloud? Low bandwidth, high latency connections will bring your operations to a grinding halt. What you need now is high bandwidth along with low latency, jitter and packet loss as a backbone to your virtual servers on the other side of the country. That means fiber optic lines and probably two of them for redundancy.

Fiber technology hasn’t been static during this expansion. Until recently you had a choice of SONET services from OC3 to OC12 and perhaps OC48. That was it. Now, Ethernet over Fiber is coming on strong as a direct competitor. Carrier Ethernet more closely matches the LAN networks that feed it. It is more scalable to meet changing business needs. Best of all, Ethernet services tend to cost less, often considerably less, than equivalent SONET fiber optic services.

But, wait! The era of copper is far from over. Just when carriers were thinking about decommissioning their twisted pair copper to let it corrode in the ground or be sold for scrap, Bonded T1 and Ethernet over Copper gain favor as business bandwidth options. While a single T1 line may be too constrained for many uses, multiple T1 lines can be bonded into a single larger bandwidth service up to 10 or 12 Mbps. Ethernet over Copper (EoC) technology uses the same twisted pair bundles as bonded T1, but a more advanced modulation scheme. EoC bandwidth is distance sensitive, but can easily deliver 10 or 20 Mbps to most businesses and 30, 50 or even 100 Mbps for short runs. Continuing development incorporating wireless techniques such as MIMO (Multiple Input, Multiple Output) for crosstalk cancelation is pushing the limits of copper into the hundreds of Mbps and even to a fiber-like Gigabit per second bandwidth.

The next decade of bandwidth is likely to be dominated by massive fiber optic build-outs for fixed locations, such as office and industrial parks, along with copper solutions to bridge the gaps where fiber doesn’t yet connect. Wireless is clearly headed for a common 4G LTE nationwide infrastructure. Compatibility will be built into portable and mobile devices, perhaps as prolifically as WiFi is now. There may be some surprises in store, such long range and interconnected WiFi hotspots or whitespace transmitters as wireless competitors, high bandwidth satellites covering rural areas better than spotty fiber and cable construction, and the development of much higher microwave frequencies (60 GHz and above) and even infrared mesh networks as new service options.

I hope you’ve enjoyed this speculative look into what’s likely to happen in the next 10 years or so, as our appetite for higher bandwidth Internet and private network connections demand satisfaction. There are many good options available right now to support your current business needs. You may not even be aware of how much development has been going on in your area to increase service levels and reduce costs. This would be an excellent time to get competitive options and quotes for business bandwidth services.

Handle Big Data With Big Bandwidth

We are said to be entering the age of big data. Just what is big data, why is it different than any other type of data, and what are the ramifications of having big data on our networks?

Big data is exactly what it sounds like. It refers to datasets that are so huge that they overwhelm normal database management tools. We’re not talking megabytes or gigabytes here. Those are easily handled by off the shelf tools. Big data is terabytes, petabytes, exabytes and zettabytes. If you don’t know what those are, just know that each named step up in size represents an increase of 1,000 times.

Where is all this big data coming from? It’s not the sort of thing you generate typing on your PC. Big data comes from computer generated simulations, process and financial modeling, research projects and sensor data acquisition and processing. Computer animation and video processing in high definition and beyond can spit out terabytes faster than you know what to do with them.

What is all this big data going to do to your network, especially your WAN network? Check out this video from Level 3 Communications to get a feel for what’s on the way and how you can deal with it...



As you can see, WAN bandwidth is likely to be the big choke point for big data. It’s because we’re used to dealing with relatively small files and modest applications such as video conferencing and VoIP. We're also used to handling incremental growth in bandwidth needs by scaling up bandwidth services we are already using.

Big data is going to change that. Instead of incremental change, we’re talking step changes. Bonding more T1 lines or moving up to a DS3 service isn’t going to do the trick. You’ll need fiber, and likely a fiber optic solution that has a lot of room for growth.

Fortunately, there a lot more fiber options available today than even a short while ago. These include Ethernet over Fiber to 1 Gbps, 10 Gbps and even 40 Gbps. Carrier core networks are now moving to 100 Gbps as quickly as they can. Other options include wavelength services over Dense Wavelength Division Modulation (DWDM) at up to 10 Gbps per wavelength and dark fiber that you can light yourself.

Are you feeling the pinch of too little WAN bandwidth right now, or see it coming in the near future? If so, this is a good time to check out your options from carriers that have the capacity to support your big data network needs. Get competitive fiber optic bandwidth options and prices for whatever capacity your business needs.

Vyvx and Genesis Offer Worldwide Video Transport

If you are involved in video production, distribution, news reporting or TV sportscasting, you have an immediate and ongoing need for video transport services. Satellites have long been used for this purpose, but worldwide fiber optic networks have benefits that include almost unlimited bandwidth, low latency and availability for many popular venues. The merger of Level 3 and Global Crossing has combined their video transport operations into an impressive array of service options.

Level 3’s Emmy Award winning video service is called Vyvx. They offer broadcast fiber services, managed video network services, teleport and satellite services and venue services. Their venue service, called VenueNet, offers dedicated access points at every major league stadium in the US. In addition to accessing the Vyvx fiber optic network, Level 3 provides high quality video encoding, Internet, telephone access and dedicated support for each venue.

The heart of the Vyvx system is a IP MPLS network with extensive reach. What MPLS brings to the table is inherent VPN security, the ability to reroute video connections on the fly if a fault occurs in the network, and rapid set up and tear down of video connections. You can plan ahead to book the service you need or get a connection at the last minute through the Vyvx 24/7 booking center. This is more difficult to do with limited bandwidth satellite services and unheard of with dedicated point to point fiber connections over traditional switched circuit telecom networks.

Within the last year, Level 3 has added uncompressed high definition video transport services between Los Angeles, Washington D.C. and New York City at 1.5 and 3.0 Gigabits per second. This offers video producers and broadcasters the opportunity to deliver live video feeds in their native, pristine form without any compression.

Another Vyvx service is Managed Video Network Service (MVNS). This is a fully managed distribution system that provides both fiber optic connectivity and the necessary equipment. With MVNS, you can distribute video feeds to multiple destinations using a web-based booking system. These feeds can be broadcasts or prerecorded content.

With the acquisition of Global Crossing, Level 3 has picked up Global Crossing’s Genesis Solutions, a formerly competing video transport service. Genesis offers global HD video over IP transmission, portable bandwidth that you can book as you need it, and point to multipoint access that can be set up immediately.

Global Crossing’s converged IP network connects 700 cities in 70 countries worldwide. The Genesis Solutions uses that network to offer specialized managed video services with compressed and uncompressed transmission options. Dedicated bandwidth is available in any increment between 2 Mbps and 270 Mbps. MPEG 2/4 compression equipment is available for encoding, decoding transcoding and compression to deliver the desired bit rate and format needed.

As you can see, there is a lot of compatibility between Level 3’s Vyvx and Global Crossing’s Genesis. The combination of the two networks adds capacity and extends the reach of the combined system to every major broadcast market in the world via fiber optic transmission. There are also eleven satellite teleports for those odd locations where fiber still doesn’t go.

Do you need full time or occasional video transport services for broadcast or program distribution? If so, don’t assume that the cost is prohibitive or that there isn’t the capacity available for the locations you have in mind. Level 3 Vyvx Solutions has both the capability and experience to handle whatever you need and whenever you need it. Check prices and options for video transport services now to confirm that your project will meet schedule and budget.

SONET Rings To Support Ethernet

The hot bandwidth service these days is Carrier Ethernet. Everybody wants it once they see the cost advantage over the WAN connection they have now. The big question is can they get it?

In most cases, the answer is yes for a couple of reasons. First, new competitive carriers are rapidly building out their fiber optic core networks based on IP from the start. These networks are tailor made for Carrier Ethernet services. It’s relatively easy to get a point to point Ethernet connection between two distant business locations and use it to link their respective LANs. The result is one larger bridged LAN that enables all employees to be on essentially the same corporate network.

The other reason that Ethernet WAN services are so readily available is that established SONET fiber optic networks are being pressed into service to deliver Ethernet to the customer. This is known as Ethernet over SONET or EoS. The core of the network is still SONET, but operations at that level are invisible to you. As far as you are concerned, your connection is Ethernet all the way.

There’s no reason that SONET can’t transport Ethernet, ATM or other protocols. It was designed as a transport technology and has been adapted over the years to carry whatever traffic required hauling. The origins of SONET, like T-Carrier, are with the telephone industry. The name is an acronym for Synchronous Optical NETwork. Note the term synchronous. That tells you SONET is set up to be a highly synchronized network. The designed is based on multiplexing thousands of small channels called DS0s that each hold one telephone call. These DS0 building blocks can be combined to create T1 and T3 lines or SONET services such as OC-3, OC-12 and OC-48.

The beauty of synchronization for circuit switched architectures based on time division multiplexing is that everything is orchestrated so tightly and you can easily multiplex and demultiplex channels and higher level services. The device that does this is called an ADM or Add/Drop Multiplexer. An ADM can drop off a T1 line, DS3, OC3 or other service at your door from a much higher speed fiber line that carries traffic for many customers.

How does Ethernet squeeze into those tiny telephone channels? It takes some doing, considering that each DS0 carries exactly 64 Kbps. That’s about the speed of an old dial-up modem. What the industry has done is replace the telephone oriented channels with large concatenated frames and various mapping techniques to more efficiently carry Ethernet packets. SONET networks can now readily carry Ethernet services from standard 10 Mbps Ethernet to 100 Mbps Fast Ethernet, 1000 Mbps Gigabit Ethernet (GigE), and 10 Gigabit Ethernet (10GigE).

A feature of most SONET networks that makes them highly reliable is their twin ring design. Two separate fiber strands are used simultaneously. Each carries the same traffic, but in opposite directions. If a fault occurs in the working ring, the network switches over to the protection ring within 50 mSec. This self-healing property works best when the two rings are widely separated so that a single backhoe cut or equipment fault doesn’t take out both rings at once.

Ethernet over SONET and native IP networks are making Carrier Ethernet services of all speeds readily available for businesses looking to upgrade their bandwidth connections at reasonable costs.

Higher bandwidths and SONET services quotes need some manual effort but will be sent to you promptly.

Fiber Lit Towers Improving Rural Broadband

Anyone situated beyond the city limits knows the frustration of living in a bandwidth-free zone. Consumers and small businesses may be near enough to a cell tower to get 3G wireless and certainly two-way satellite is an option, but with severe download restrictions on both. Business sites and farmsteads can probably get T1 lines at 1.5 Mbps and maybe bonded T1 lines to improve a bit on that. How about high bandwidth wireless? Forget it. Fiber optic Ethernet connections? Are you nuts?

Rural America is truly at a disadvantage compared to the telecommunications resources found in cities and suburbs. The best options are found in the core of large metropolitan business districts. Move downtown in a big city and you’ll find such niceties as Gigabit Ethernet and even 10 Gig E connections. You may even be able to get Ethernet over Copper at 100 to 400 Mbps. Fixed wireless services easily deliver 50 to 100 Mbps bandwidth. If a shared bandwidth solution is OK for what you are doing, it’s hard to beat the Cable MSO prices.

Why the big discrepancy between metropolitan and rural service options? It’s all about infrastructure - the infrastructure that was never installed. Well, that’s in the process of changing right now. Level 3 Communications, one of the premier international telecom carriers, has established a program called EON or Extended On-Net sites. What they are doing is building out 500 additional access points to their fiber optic network. They are mostly in small and rural markets where there are few service options available. This is a wholesale, rather than retail, service intended to give local service providers access to high bandwidth carrier services.

Even with fiber optic gateways in the boonies, you still need a way to get the signals to the businesses and consumers without having to spend a fortune creating the remainder of the needed infrastructure. One technology that makes excellent sense for thinly populated areas is fixed wireless. WiMAX is an example of wide area coverage with significant service speeds. What you need, then, is access to the carrier-class fiber bandwidth plus a tower to transmit that bandwidth wirelessly to users scattered far and wide.

This sounds like a perfect opportunity for a combined effort and such a deal has been made. 52Eighty, a provider of tower infrastructure, has entered into an agreement with Level 3 to create 200 new wireless tower access sites situated near Level 3’s EON gateways. 52Eighty will take care of tower construction. Level 3 will provide transport and services that include private line, Ethernet and wavelength services. EON also offers backhauls that include Internet, VPN and voice services.

If this sounds a lot like what has been called the rural broadband initiative, it’s because that’s exactly what is going on. Level 3 is a key “middle mile” provider in bringing high speed network access to rural areas where local service providers can connect. They were awarded $13.7 million this summer through the American Recovery and Reinvestment Act and matched it with $4.2 million of their own funds to create dozens of middle mile connections in rural California, Florida, Georgia, Kansas, Tennessee and Texas.

Does this mean that relief is coming to disconnected consumers and businesses in Rural America? It’s certainly on the way. In fact, many carriers are expanding their wireline, broadband and fiber bandwidth services to garner new customers. If your ISP or business has been unable to get connectivity in the past, now is a good time to check availability and prices online for fiber optic lines to 1 Gbps, plus T1, ISDN PRI and other bandwidth services. You may be surprised by what has become available recently.

GigE and FastE Bandwidth Services

Bandwidth upgrades are a matter of course these days. Many companies are moving from T1 line speeds at 1.5 Mbps up to 3x3 Mbps or 10x10 Mbps Ethernet. Often there is little or no additional cost involved in doing so. But what if these bandwidth levels are still to low for your needs? Are there any opportunities at the 100 to 1000 Mbps level?

Carrier Ethernet is now the service to pursue at medium and high bandwidth speeds. These service levels have been dominated by DS3 or T3 lines at 45 Mbps and SONET OCx for higher line speeds over fiber optic cable. Ethernet bandwidth has a cost advantage for this need and also provisioning flexibility.

It’s common knowledge that low and mid-band Ethernet services are readily available over twisted pair copper wiring. In other words, the same telco wires that you currently use for analog business phone lines and T1 lines can also be used to transport Ethernet protocol. The service requires specialized equipment at each end and multiple copper pairs. This is Ethernet over Copper. Bandwidth levels vary from 1 Mbps on up 100 Mbps and beyond. A 200 Mbps service is available in some areas and a new 400 Mbps asymmetrical Internet access is being rolled out.

Most companies opt for Ethernet as a last mile connection to the Internet, metro or wide area MPLS network with bandwidth up to 50 Mbps. This is a direct replacement for their existing copper wire T1, bonded T1 or DS3 connections. By moving up the speed range to 100 Mbps to 400 Mbps, Ethernet can directly replace such fiber optic services as OC-3 at 155 Mbps and perhaps OC-12 at 622 Mbps.

All of this is done over up to 8 bonded copper pair at distances that don’t exceed a few thousand feet to a few miles from the telco central office. This is no problem in densely populated business districts, but as you move out into the burbs, small cities and rural areas, service becomes less available. Ethernet over Copper has a definite distance limitation.

Fast Ethernet at 100 Mbps may be available over copper, but Ethernet over Fiber is a better bet. The beauty of fiber is that once you have it installed and your building is “lit”, just about any bandwidth is possible. That includes FastE, of course, at 100 Mbps, GigE or Gigabit Ethernet at 1,000 Mbps and 10 GigE or 10 Gigabit Ethernet at 10,000 Mbps.

Ethernet over Fiber is available from traditional telephone companies, but it is also available from competitive carriers who have built their own IP-core regional and national networks with Ethernet as a standard service. These companies can bring Ethernet right to your building without having to lease any telephone company facilities. This gives them the ability to offer more bandwidth for less money. You may save half or more for equivalent service levels at the higher bandwidths.

A new wrinkle is Ethernet over Fiber offered by Cable MSOs. This fiber was bought and paid for by the Cable Television industry, but has so much extra bandwidth available that these companies are offering access to their fiber optic networks to businesses and other organizations that need anywhere from 10 to 1000 Gbps. That includes Fast Ethernet and Gigabit Ethernet at prices that are up to half the cost of other fiber providers.

The options are many and the prices are very attractive right now. There is lots of bandwidth to go around, which may not be true when the economy takes off again. If you need to speed up your networks, you can lock in some excellent deals. Check prices and availability for GigE and FastE bandwidth services appropriate for your business location.

The Coming Level 3 Global Crossing Juggernaut

If you believe that the future of business is high bandwidth connections to clouds, customers and suppliers worldwide, then the next step toward this future is the melding of Level 3 Communications and Global Crossing. Combine their assets and you have a network map that spans the world.

Level 3 Communications is actually purchasing Global Crossing for $2 billion. When this merger is complete, their combined fiber optic assets will reach 70 countries on 3 continents.

Level 3 has an extensive long haul network with metro fiber in many US cities. Their transatlantic undersea fiber connects to a European network to link the USA and major European cities with low latency fiber connections. Level 3 is a major player in the high speed financial trading space, as well as providing other high bandwidth fiber services for global business needs.

Another strength of Level 3 is video transport. Their Vyvx service carries both high definition and standard video programming for studios and networks. For the highest in transmission feed quality, Level 3 Vyvx offers uncompressed high definition video transport services between Los Angeles, Washington D.C. and New York City at 1.5 and 3.0 Gbps. The Level 3 Content Delivery Network (CDN) has 35 strategically placed cashing locations to keep the content as near the customer as possible.

What Global Crossing does is complement rather than compete with Level 3’s US/Europe network. Global Crossing has over 100,000 route miles of fiber optic cable installed around the world. This includes US and Europe network fiber that overlaps Level 3 to some extent. But it also brings trans-pacific undersea fiber and connections to Japan, China, India, Australia, New Zealand, South Korea, Malaysia, Thailand and the Philippines. Connected to its North America network is an extensive fiber optic networking serving the major cities in South America.

Global Crossing is true to its name. Their fiber really does span the world. Add Global Crossing’s network to the Level 3 network and you have extensive connectivity throughout North America, South America, Europe, Australia and Asia, with some facilities extending to the Middle East and Africa.

What does this mean for you, the business user? It certainly means more availability of converged IP network services worldwide and specialty services, such as low latency routes and video transport. Both Level 3 and Global Crossing have been serving major enterprise customers and carriers. They’ve got the expertise and facilities to accomplish whatever you will ever need in the way of connectivity.

Level 3, especially, also caters to smaller and medium businesses in the US. Their T1, bonded T1 and Ethernet over Copper solutions offer dedicated bandwidth at very reasonable prices. For companies that need to link multiple locations, Level 3 MPLS can create a company network that spans the country and extends to include offices, factories and warehouses worldwide.

Fiber optic networks are enjoying a new renaissance, as businesses move to cloud processes and automation that increases employee productivity. You see more fiber going into the ground in both major cities and rural areas. If you’ve been affiliated with Level 3 or Global Crossing, your connection capabilities are about to be increased significantly.

If you are looking to increase your connection speeds, you’ll probably be pleasantly surprised by the wide range of services available and the cost reductions that have come about in recent years from these and other competitive carriers. Don’t assume that you can’t get or afford higher bandwidth, even fiber, until you get prices and availability for business bandwidth services appropriate to your facility locations.

Even Lower Latency Connections To Chicago

If you’ve been wondering just how important network latency has become, note that AboveNet is installing shorter fiber optic routes just to link Chicago and its suburbs. That network will be in operation by mid-next year. Can other cities be far behind?

Latency is the new bandwidth. It’s the scarce resource when you need really, really high performance in your computing environment. Who needs such performance? The big driver has been financial companies that trade on the stock and commodity exchanges. That’s why Chicago, as a major financial center, is being targeted for the AboveNet buildout. New York is another hotbed of activity, with colocation near financial exchanges in high demand. Since we are in a global trading economy, low latency connections to Europe and Asia are also enjoying enormous growth.

Why the need for speed, and why doesn’t more bandwidth solve this problem? Latency and bandwidth are two different animals. Latency is how long it takes a packet to get from point A to point B if there is no interference from other traffic. Bandwidth is the sheer volume of traffic you can handle before packets start piling up at the choke points.

To someone with a too-small WAN network, it might seem that latency and bandwidth are the same thing. That’s because a bandwidth-limited system slows down transmission a lot more than the effect of latency. But once you have enough bandwidth to keep up with the amount of traffic you can actually send and receive, then the network is going as fast as it can. Increasing bandwidth won’t make those packets fly down the line any faster. They’re inherently limited by the speed of light and electrical delays within the circuitry.

You get a dramatic feel for the effect of latency when you watch those television interviews from locations thousands of miles away. They connect to the studio using microwave trucks that beam the signal to a geostationary satellite 22,236 miles above the equator. The signal goes from the truck 22,236 miles up to the satellite and then comes back down 22,236 miles to the television studio. That’s a quarter of a second delay one way or about half a second for a conversation at a minimum. You find it either comical or annoying to listen to the reporters at both locations tripping on each other.

How do you reduce that latency? Take as much equipment out of the path as possible and make the path as straight a line connection as possible. Not much you can do with a geosynchronous satellite. They only work at that altitude. Just don’t try to use one for VoIP telephony or any sort of interactive process or you’ll get frustrated quickly. Fiber optic cables are the high bandwidth connection of choice, but even they are not created equal. Some networks, like the Internet, may take a circuitous route to get packets from one location to another. The Internet was designed to get the packets delivered even under multiple fault conditions. It wasn’t designed to get them delivered particularly fast.

What’s better? Privately run fiber optic networks, like national and international MPLS networks, do a decent job. Even these are designed for normal business requirements and aren’t optimized for minimal latency. What you need are networks specifically designed to minimize latency. They feature very straight runs from location to location, very few switches or routers on the path, and termination as close to the users as possible.

High frequency trading has highlighted the need for low latency networks, but as business moves more and more into the cloud, other processes will drive their own needs for this level of performance. Disk mirroring and data replication are two applications that already benefit from lower latency connections. Cloud computing over multiple locations could easily have the same requirement.

Are your business processes latency sensitive? If so, you should seriously consider the newer low latency network services offered by AboveNet and other competitive carriers. There are microseconds, even milliseconds to be saved.

What Is Lowering Gigabit Ethernet Bandwidth Pricing?

If you have recently gone out for quotes on Gigabit Ethernet bandwidth, you may have been surprised by how much prices have dropped the last few years. That’s one pleasant surprise for organizations that need higher levels of business bandwidth for cloud computing access, e-commerce, medical image transmission, video distribution and the like. But is this for real and what is driving these prices lower?

Yes, it’s for real alright. In fact, bandwidth services across the board can be had for a fraction of what you may have paid when you signed your last service contract. That applies to everything from T1 lines to DS3 connections and on up through OCx SONET/SDH fiber optic bandwidth. It also includes competing services like Ethernet, Fast Ethernet, Gigabit Ethernet and 10 Gig E. Plus multi-location cloud networks like MPLS. They’ve all dropped in price. But the cost per Mbps is often most dramatic for Ethernet services.

What’s behind the lowered prices? Two factors can be credited. First is the move from traditional switched circuit transport technologies to packet switched IP networks and services. Second is new levels of competition.

Both legacy service providers, the telephone companies, and new competitive carriers have built-out extensive networks based on IP or a networking technology that embraces IP, such as MPLS or Multi-Protocol Label Switching. You can thank the Internet for that. The enormous volume of equipment and services to support near-universal demand access to the Internet has decreased the price of Ethernet and IP networking to a fraction of what it costs for competing technologies. The entire world is going to packet switched networks based on Internet Protocol.

When every LAN is running Ethernet, it just makes sense that the most efficient way to connect all those local area networks is with an Ethernet connection. Ethernet over Copper lets you do this from typically 3 Mbps on up to around 50 Mbps. Ethernet over Fiber is good for 100 Mbps Fast Ethernet, Gigabit Ethernet, and even 10 Gigabit Ethernet. Gigabit Ethernet is becoming a requirement for medium and large companies depending heavily on high productivity enterprise software or distributing media content, such as video. At the very highest levels, even 10 GigE is no longer out of the question.

The move from legacy telco technologies to IP based fiber optic networks has brought new players into the marketplace for WAN networking services. These competitive carriers have built their own regional or national fiber optic networks and established colocation facilities and points of presence in most major cities, even some mid-size cities. They can often bring their own fiber into business locations and bypass the telephone companies completely. Now instead of one option for service, you may have several or more even at the Gigabit Ethernet level. That spells competition and competition leads to lowered prices.

Could your organization benefit from the recent cost reductions in high bandwidth networks services? Don’t shake your head no until you check current prices and availability for Gigabit Ethernet bandwidth services and other bandwidth offerings. At the very least, your next service lease could cost you less than the one you have now.

Fiber Plus Copper Equals High Bandwidth

We’re bandwidth hungry and getting more so by the day. Both businesses and consumers are finding themselves frustrated by their inability to take advantage of all the latest technologies due to bandwidth limited connections. Productivity vendors and content providers are in the same fix. They’re having a hard time delivering everything they can produce simply because the demand for transport and last mile bandwidth has exceeded the supply.

This situation is reminiscent of the early days of the personal computer. For several decades you just couldn’t get enough processor speed, RAM memory or hard disk capacity. Cheap RAM, huge disks and multi-core processors have pretty much eliminated this bottleneck. Well, not completely. You still find yourself having to upgrade your machines every few years to keep up with the demands of applications, especially video. But today’s limitations on progress are more related to the size of the pipe than the size of the machine.

Seems like the solution is pretty obvious. All we need to do is replace our outmoded copper infrastructure with fiber optic bundles and we’ll have all the bandwidth we can use.

In a sense, that’s what’s happening. Nearly all carriers have embraced fiber optic IP networks and are expanding their fiber footprints as fast as they can. But to think that we’re going to completely retrofit a century and a half’s worth of copper build-out with fiber optics on a one to one basis is just fanciful. Even today there’s no standard that mandates fiber optic service for new homes and businesses as a utility. You can bet that every building gets universal phone service delivered over twisted pair copper. But how many have a multi-fiber bundle terminated on the premises?

Someday fiber optics will be the default for voice, data and video. Copper will be for power. But today’s reality is that most bandwidth will be delivered to homes and businesses over standard copper telco wiring. Fortunately, technology has come to the rescue with new modulation techniques to squeeze higher and higher bandwidths from already installed copper wiring.

For businesses, the hottest bandwidth service right now is called Ethernet over Copper. It is becoming the upgrade of choice by companies who have tapped out the capacity of their T1 lines but can’t afford the construction costs to bring in fiber connections. The new terminal equipment combines the capacity of multiple copper pair to create a single wide bandwidth Ethernet service from carrier to user. The bandwidth is anywhere from 1 to 50 Mbps over a distance of a few blocks to a few miles.

That’s a considerable increase for many small businesses, although medium and larger companies still need to pony up for fiber to get the 100 Mbps to Gigabit Ethernet connections they need. But what about the consumer and companies that have a crying need for higher bandwidth but don’t have the budgets yet for fiber?

AT&T is pursuing a solution for residential users called FTTN or Fiber To The Node. This is a hybrid arrangement that uses the high bandwidth of fiber to get close to a neighborhood and then leverages the value of the already-installed telephone wiring to carry the signals into the home. It’s a way to jack up the speed of DSL way beyond what copper can carry all the way from the central office. How fast? AT&T is reportedly going to start trial service at 80 Mbps next year. That’s faster than the speedy 50 Mbps broadband service offered by Cable’s upgrade to DOCSIS 3.0 modems and even Verizon’s FiOS. Of course, both fiber and Cable have room to increase their speeds as competition demands. But perhaps AT&T can also push the envelope to 100 Mbps and beyond.

FTTN advances can benefit business, too. In metropolitan and suburban areas, carriers establish POPs or Points of Presence where they can connect to their fiber networks. From there they can “light” buildings with fiber service or provide EoC or Ethernet over Copper. The more fiber services there are in a particular area, the more options you have for both fiber and copper bandwidth at reasonable prices with minimal or no construction costs. Knowing where the high bandwidth services are already installed can also be a strategic advantage. If you are looking to relocate anyway, it just makes sense to find a location that already has the network services you’ll be needing.

Fiber Optic Networks Need Denser Wavelength Multiplexing To Meet Demand

Just when you thought that businesses were hunkering down for the worst recession ever and wouldn’t need more capacity for a decade, fiber optic network carriers are scrambling to meet demand. But they’re not going nuts and digging trenches everywhere. Instead, they are taking the smart approach of using technology to increase bandwidth on their installed facilities.

XO Communications, a major fiber optic network carrier, recently announced that it is installing new optical line equipment from Infinera to double its capacity per fiber strand. The Infinera Line System 2 doubles the number of channels for C-band fiber optic systems (1550 nm) from 80 to 160 channels. For XO, this will create an additional optical capacity of 1.6 Terabits/second (Tbps) on their nationwide network.

What is XO hoping to do with all this additional bandwidth? They are using it to support their carrier to carrier services called “Carrier Wavelength FLEX” and “10 Gigs in 10 Days.” With the new Infinera hardware and software, XO Communications will be able to provision any service from 1 Gbps to 40 Gbps between any two points on the network in 10 days or less. In the future they plan to up that to 100 Gbps.

What XO is doing is really two initiatives at once. One is doubling capacity and making it scalable for future expansions. The other is speeding the process of provisioning service so that their customers, other carriers and businesses, can respond more quickly to marketplace needs. You might say that faster is better all the way around.

Certainly, XO Communications is making a move to position itself as a provider of choice as demand for bandwidth picks up. But they may also recognize that business coming out of this turndown may look somewhat different than it did going into the slide.

For one thing, technology is being seen by all size operations as a way to improve productivity at lower risk and lower cost that simply staffing up. Technical solutions can drive cost out of a process and reduce the amount of labor needed to support a given business level. Telecommunication capability is more vital than ever as solutions migrate toward the “cloud” and business entities are coupled more and more tightly.

The nature of many business services is also changing in a way that demands more bandwidth. Take television and video production, for instance. High definition and, soon, 3D images are far more demanding on digital bandwidth than lower resolution products. The health care industry seems destined for a complete move from paper forms and photographic processes to all-electronic generation, transmission and storage. Certainly, this will improve productivity and take incremental cost out of the processes, but there will be big infrastructure investments to be made before the massive cost savings can be realized.

New Dense Wavelength Division Multiplexing (DWDM) equipment, such as Infinera’s Line System 2, will be critical to all carriers as they look to increase capacity over their installed base of fiber optic strands. XO is simply getting a jump in upgrading their network before the mad scramble begins. That could be any time now.

If you are feeling bandwidth constrained in your business operations, you should know that lease prices per Mbps have dropped considerably recently. You may be able to upgrade to the level of service you need without the jaw dropping cost you are anticipating. How do you find out for sure?
