Carrier Neutral Connectivity at Colocation Data Centers

By: John Shepler

Companies feeling starved for bandwidth may not realize that they’re doing it the hard way. Instead of making the carriers come to you, there are advantages in you going to where the carriers are.

It’s All Happening at the Colo
The places where carriers flock are called colocation or colo centers and carrier hotels. These are large data centers that are meant to serve a variety of tenants. Contrast that with the typical data center that serves only a single company. In fact, most companies want nothing to do with renting out space in their data centers. The security issues alone make them blanch.

Why Do Colocation Centers Exist?
It has to do with economy of scale. Say you have 100 companies and each one needs a data center. They may well construct their own in-house data centers sized to meet their needs. This involves creating a dedicated space that is environmentally controlled, secure, with fire protection and backup power. Uninterruptible power supplies based on batteries and inverters cover short term power glitches. Anything over a few minutes depends on diesel or gas generators outside.

Data Center Costs
As you might expect, there is considerable cost involved in building and running a data center. Aside from the initial capital investment, there are constant operating costs involving air conditioning, electric power and support personnel. These costs persist regardless of business level and the equipment may sit idle for two-thirds of the day. Smaller companies often can’t justify the expense of round-the-clock tech support.

Connectivity Counts
What level of bandwidth you can get and how much it will cost are largely a function of where you are located. If your offices are in a smaller town or rural area, you may have only a single provider to pick from and severe bandwidth limits.

Economy of Scale
Now, what if those same 100 companies decided it would make more sense if they all moved into a single much larger data center that would serve all of their needs. You might think the overall total cost would be similar, but actually they would be much lower.

It’s the economy of scale that saves. Each company only needs racks and cages large enough to house its servers and other equipment. A few larger backup generators can supply emergency power when needed instead of 100 smaller generators on standby. A common security force can handle access control and monitor intrusion sensors. A common tech support group can handle the occasional needs of all companies 24/7.

From Owner to Renter
The tenant companies switch from an ownership to a rental model. They don’t need to overbuild, because they can always rent more or less facilities as needed. The colo operator takes the responsibility of building the facility, providing utilities, security and tech support.

A Magnet for Carriers
Have you ever had a carrier tell you that it’s just too expensive to bring fiber optic service to your company? They might do it, but you’ll be responsible for the construction costs and they can be eye-popping. The colo center, howler, acts like a carrier magnet. They see 100 potential customers for their service and make their fiber available. Most colo centers are near populous areas, making the construction relatively easy.

Will you have a carrier to provide you bandwidth service at the colo? Most likely, you’ll have at least several and perhaps a lot more. Each carrier has its own colo space with racks and cages. It costs them little more to bring in high bandwidth service for 100 companies than a single customer. That, plus the competition of having multiple carriers bidding for your business, makes pricing more attractive than it might be to your own facility.

Meet Me for Service
Colos have an ingenious setup called the “meet me” room or MMR. This is an area dedicated to making cross-connections. The colo operator runs copper or fiber cabling to your racks from the MMR. They also run copper or fiber from the carriers to the MMR. When you contract for bandwidth, the colo patches you to the carrier and you’re all set. If you change your mind, you can work out the next contract with a different carrier and the colo will simply move your patch cord.

One additional advantage of using an MMR is that there is no “local loop” charge because the colo is providing the “last mile” or, in actuality, “last foot” connection.

Two Types of Colos
You should know that there are a couple different types of colos. One is operated by a single carrier. They build the facility for their own needs and then rent out extra space. You can get really high bandwidth and reasonable prices in such a facility, but you may have only one or a few carriers to pick from.

The second type of colo is operated by a third party who is in the colocation business and doesn’t favor any customer or carrier. These are often called carrier neutral facilities because you aren’t required to connect to any particular bandwidth provider.

Clouds and Colos
Cloud services are often located in colocation facilities. This gives the cloud provider a facility to support their extensive servers and storage. If you are collocated within the same facility, then it’s a simple wire or fiber connection to hook you up with one or more cloud service providers.

Are your data center costs higher than you would like or are you having trouble getting the WAN bandwidth you need to support your business? This would be a good time to investigate what’s available from a number of colocation centers and cloud service providers.

Comcast’s 100 Gbps Core Network Supports Business

Major telecom carriers have been in the process of upgrading their core networks from 40 Gbps to 100 Gbps over the last year. Comcast is the latest to make the move, fitting Ciena’s Wave Logic 3 interfaces to their current Ciena 6500 packet optical platforms. Why would a cable company do this and how can it benefit your business?

Comcast is best known as a Cable TV company or MSO (Multi-System Operator). They serve over 20 million residential and commercial customers in 40 states and the District of Columbia with video television, high speed Internet and telephone services. You may already know that Comcast broadband service is highly popular for home, home office and small business use. It comes in on a coaxial cable and is highly affordable. But did you also know that Comcast operates one of the largest fiber optic networks in the United States behind the scenes?

Many people think that cable companies still connect everything from their head-end towers and satellite dishes to locations around town using various size coax. That was true in the early days of analog TV cable systems and master antennas for large apartment buildings. The technology has long since moved on. Now everything is digital and the signals ride fiber optic cables most of the distance to your location. It’s that connection from the curb to your building that is still RG-6 coaxial copper wire.

Why? Because it works just fine and the cost of installation has already been paid. DOCSIS 3.0 modems offer broadband Internet in excess of 100 Mbps. That’s is well within the needs of most users. What’s really important to residential, home office and very small business users is low monthly cost combined with adequate performance. The shared asymmetrical bandwidth (higher download than upload speeds) and “best effort” performance is more than adequate for accessing the Internet and downloading documents, pictures and video.

Where HFC (Hybrid Fiber Cable) services run out of gas is when the need for bandwidth is high, dedicated low latency service is needed, symmetrical upload and download speeds are required, and an SLA (Service Level Agreement) is desired. These characteristics are common for traditional telecom services such as T1, DS3 and SONET fiber and the newer Ethernet services such as FastE at 100 Mbps, GigE at 1000 Mbps and 10 GigE at 10 Gbps.

What isn’t as well known is that Comcast operates an enterprise grade fiber optic core network to interconnect their many offices and provide high bandwidth connectivity to businesses. Would you be surprised to learn that Comcast operates a network that covers 147,000 fiber route miles? How about that business class services are available from 1 Mbps on up to 10 Gbps? Their business class services include dedicated Internet access, point to point Ethernet private lines, Ethernet LAN service to interconnect multiple business locations and converged layer 2 centric VPLS to support voice, video and data.

Comcast, like other major fiber optic carriers, recognizes the increasing demand for higher and higher bandwidth services. What’s driving these speed increases is more use of HD video, big data files and a rapid move to cloud computing services. The cloud, especially, present new challenges for businesses used to having all their processing in-house and connected over the corporate LAN. Cloud service providers offer the opportunity to rapidly scale resources up and down, pay only for what you use during the month, and avoid both capital investments and ongoing maintenance costs. The tradeoff is that you now need much higher and very reliable bandwidth to connect your employees to the cloud.

Comcast’s upgrade to 100 Gbps fiber optic bandwidth meets today’s perhaps tomorrow’s needs for their own use and in support of small, medium and large companies. When even this massive capability fills up, the Ciena system they’ve chosen has an upgrade path to 400 Gbps. It’s likely that we’ll see even higher speeds at 1 Tbps and beyond sooner than anyone expects.

Are you running short on bandwidth and wondering how much you can afford as an upgrade? Get multiple competitive fiber optic service quotes for Comcast Business and other high performance fiber optic carriers now. It’s likely that you can turn up your WAN bandwidth at little or no increase over your current monthly least cost.

Eastern Tennessee Gets Lit for Business Fiber Optic Service

It is well known that Nashville, Tennessee is a major hub for many fiber optic network providers. As a major center for commerce in the South, there are many health care, publishing banking, transportation and, of course, music companies that need the high bandwidth you can only get with fiber optic connections. This need is becoming more and more important beyond Nashville, throughout the entire state of Tennessee.

This is why EarthLink, a major bandwidth service provider, has recently completed a major buildout of fiber assets that cover Eastern TN cities. It includes a 343 mile fiber route from Nashville to Knoxville, a diverse fiber route from Knoxville to Chattanooga and another fiber route from Knoxville to Bristol. There are network interconnection points in Cookeville, Oak Ridge, Cleveland, Sweetwater and Morristown. Major POPs are located in Knoxville, Morristown, Johnson City and Bristol.

EarthLink’s Points of Presence (PoPs) on the Eastern Tennessee Middle Mile Broadband Project can deliver up to 10 Gbps DWDM optical services. DWDM or Dense Wavelength Division Multiplexing is a technique used to multiply the bandwidth capacity of fiber optic links. Instead of using a single laser beam to carry the traffic, DWDM uses dozens or more lasers of different colors (wavelengths) to create independent high bandwidth carriers through the fiber strand. Each wavelength is an independent channel and does not interact with the other wavelengths on the strand. It’s like multiplying your fiber optic cable by 10x to 100x the capacity.

In addition to providing high bandwidth connections directly to businesses and universities, EarthLink has the capacity to offer fiber optic services up to 10 Gbps on a wholesale basis to Internet service providers (ISPs) that serve smaller businesses and consumers, especially in smaller communities. One of the big stumbling blocks to expanding rural broadband has been the lack of what’s called “middle mile” infrastructure. It is this middle mile backbone that EarthLink has deployed. Other ISPs connect to the backbone and then provide “last mile” connections directly to users. Some ISPs do this wirelessly and are known as WISPs or Wireless Internet Service Providers.

EarthLink headquarters are located in Atlanta, GA. More than a regional carrier, EarthLink owns and operates 28,000 route miles of fiber, 90 metro fiber rings and 4 data centers to serve nearly all of the United States. Business connectivity services include MPLS networks, Internet access, data T1 and bonded T1 lines, full and fractional DS3, SONET full and fractional bandwidth at OC-3 (155 Mbps) OC-12 (611 Mbps) and OC-48 levels (2.5 Gbps), metro fiber Ethernet and SIP trunking. In addition, EarthLink provides other network services, such as managed security, hosted PBX, colocation and cloud hosting.

What’s driving the need for all this fiber optic bandwidth? Business technology has changed rapidly over the last decade or so. Small and well as large companies now find their business processes IT driven. The benefits have been wider communication, faster agility and higher productivity. Some industries, like video production and delivery, are inherently high bandwidth in nature. They can’t function without fiber level bandwidth. Many others are finding that the large cost savings they can realize by moving to the cloud comes with a new requirement. Where once lower speed wireline services could handle communications in and out of the company, the cloud makes all servers remote and requires fiber speeds to prevent productivity killing latencies.

How about your company? If you are located in Eastern Tennessee or anywhere else in the country, there are new fiber assets available at better prices than ever before. Get competitive quotes on fiber optic services for business to support your demanding needs.

Metro Ethernet Networking Technology

Metropolitan Area Networks (MAN) are well established as a way for businesses to transport their traffic within a given metropolitan area. Now the MAN is becoming the MEN, or Metro Ethernet Network. Let’s take a look at what this new technology has to offer.

Metropolitan or Metro Ethernet Networks are based on Carrier Ethernet standards established by the Metro Ethernet Forum (MEF), and industry standards group. This ensures that you know what services you are getting and that you can directly compare these services from provider to provider.

Why bother with Metro Ethernet when the MAN connections you have now are working just fine? While these services are no doubt running reliably and getting the job done, you may be missing out on service options that could better meet your needs. You many also be paying more than you really have to.

The core networking technologies of Metro E networks could be pure IP networks or they may be Ethernet services running on top of legacy SONET fiber optic networks. That’s a perfectly legitimate technical approach. Protected SONET rings have a history of high reliability, low latency and considerable bandwidth. As a user, having to deal with SONET at the SONET level does limit your options compared with Carrier Ethernet. You can be better off with Ethernet over SONET or Ethernet over IP core networks.

SONET is a TDM or Time Division Multiplexing technology with all traffic loaded into neat little time slots lined up one right after the other. An ADM or Add/Drop Multiplexer handles getting specific traffic on and off the network. Your connection is by one of the standardized Optical Carrier levels, such as OC-3 (155 Mbps), OC-12 (622 Mbps), OC-24 (1.24 Gbps) or OC-48 (2.5 Gbps).

Carrier Ethernet is based on packets rather than time slots. Packets are distinguished by the information in their headers that are read by switches and routers. This is the same Ethernet than runs on your company LAN. That’s the first advantage of Metro Ethernet. It’s directly compatible with LAN Ethernet so there are no inefficiencies from protocol conversions between dissimilar networks.

The other obvious advantage is interfacing. Connections to Metro E is a conventional Ethernet connector. At lower bandwidths, including 10, 100 and even 1000 Mbps, a standard RJ-45 connector can suffice. Higher bandwidths have fiber optic connectors.

Carrier Ethernet is designed to be both highly and rapidly scalable. You can generally get far more bandwidth options than are available with SONET levels. They are also easy to scale up and down. What sets the limit on your bandwidth is the port speed that you connect through. If you have a 100 Mbps port, you can specify any bandwidth up to 100 Mbps. With a Gigabit Ethernet port, you can get any bandwidth up to 1,000 Mbps. Likewise a 10 Gig E port lets you scale to 10 Gbps. The GigE port is very popular for this reason. You can call up your provider and move up from 200 to 400 Mbps in a matter of hours or days. There is no need to change hardware interfacing as long as you are operating below the maximum port speed.

Metro Ethernet Networks can give you the same point to point connections that you are getting now or a multipoint service that operates as a LAN extension. E-Line is an Ethernet Line Service. E-LAN is an Ethernet LAN service. E-LAN can run at layer 2, letting you connect multiple metro locations together in one large bridged LAN. This is a popular service for companies with multiple offices, factories, warehouses, retail outlets and so on within a given metropolitan area.

All My Access Is In Texas

If the state of Texas is where you do business, you’ll want to be aware of Alpheus Communications and their regional network connecting the major cities in Texas. In addition, they have colocation data center facilities in the Lone Star State. This gives you the advantage of security, reliability and low cost connectivity while keeping everything reasonably nearby.

The Alpheus regional fiber optic network offers high bandwidth and low latency between Dallas, Fort Worth, Waco, Bryan, Austin, San Antonio, Laredo, McAllen, Harlingen, Corpus Christi, Victoria and Houston. Long haul connections can take your traffic anywhere in North America at bandwidth speeds ranging from DS-1 (1.5 Mbps) up to OC-192 (10 Gbps).

Network connectivity is available in a wide range of options. These include Dedicated Internet Access (DIA), Metro Ethernet, Private Line and Managed Wavelength. Alpheus clients can connect with each other through a cross connect arrangement called Metrolocity. You can choose from bandwidth speeds ranging from DS-1 to OC-12 (622 Mbps) and peer with other enterprises and competitive communications service providers. You do not have to colocate or build facilities to other carriers to make these connections. They’re provided by Alpheus as part of their Metrolocity peering.

Alpheus operates four hub facilities in Houston, Dallas, Austin and San Antonio. Their network operations center (NOC) is also located in Houston. The Austin and Houston data centers are SAS 70 Type II Audit Certified to meet the demanding needs of enterprise clients. These data centers give you the security, reliability and scalability you need to host enterprise applications, disaster recover solutions, high performance websites, Software as a Service (SaaS) applications and general IT operations infrastructure. You’ll find hubbed and point to point service from DS-1 to OC-192, Gigabit Ethernet and 10 Gbps managed wavelengths.

Some clients find even SONET, GigE and wavelength services too limiting. To meet their needs, Alpheus Communications offers dark fiber solutions. With dark fiber, capacity is determined by the terminal equipment, usually DWDM (Dense Wavelength Division Multiplexing). In essence, you become operator of your own fiber optic network. That means you have the ability to transport any protocol or multiple protocols at once. Leverage wavelengths to create massive bandwidth for transporting near-limitless amounts of information.

Perhaps a Gigabit Ethernet connection is enough to meet your needs. Alpheus is set up to connect you across the metro markets in Texas or across the country.

Ethernet and Colocation For Texas Business

The Lone Star State is a land of big spaces, big business, big data and the need for big bandwidth. Alpheus is a carrier with both Texas roots and a focus on the needs of Texas business. Let’s take a look at the services they offer to meet the needs of companies in banking & finance, energy, government, healthcare, information technology, legal and media sectors, among others.

With a Network Operations Center (NOC) in Houston, the Alpheus fiber optic network connects major cities in Texas. Their Texas regional network connects to Dallas, Fort Worth, Waco, Bryan, Austin, San Antonio, Laredo, McAllen, Harlingen, Corpus Christi, Victoria and Houston. Core network reliability exceeds 99.999% or “five nines,” the gold standard for telecommunications.

Alpheus serves both enterprises and carriers within their Texas footprint. Network services include Dedicated Internet Access (DIA), Metro Ethernet, Private Line and Managed Wavelength. One of the newer services is Ethernet-Over-Local-Area-Network (E-LAN). This is a Carrier Ethernet service standardized by the Metro Ethernet Forum (MEF) and used to bridge multiple local area networks so that they act as one much larger network.

If you’ve been trying to tie business locations together with traditional telecom services, you know that there is a transition between your network edge and the telco providers network. Usually this means a protocol conversion and specialized interface hardware. What E-LAN does is eliminate that transition by keeping everything in the Ethernet protocol from end to end. A simpler service called Ethernet Line or E-LINE provides a dedicated point to point Ethernet connection between two locations as a replacement for private line services such as T1, DS3 and OC3.

Alpheus Carrier Solutions include Metro transport with rates ranging from DS-1 (1.5 Mbps) to OC-192 (10 Gbps), Texas Long Haul for connecting from Texas Metro markets to virtually anywhere in North America at the same speeds as Metro Transport, Metrolocity Peering to cross-connect with other service providers with bandwidth speeds from DS-1 to OC-12 (622 Mbps), Ethernet services to 10 Gbps, and 2.5 Gbps managed wavelengths. Ethernet interfaces include 10/100 Mbps FastE, 1000 Mbps GigE and 10 Gbps Ethernet. Scalability is flexible from 1 Mbps on up to 10 Gbps to match user requirements.

Alpheus Waves and Gigabit Ethernet services offer 3 levels of protection. Load sharing consists of two interfaces with two physically diverse unprotected connections. Your provide the protection switching. Network protection is configured to protect against network outages but not client issues. Unprotected services are just that. There is no network or client protection.

Alpheus operates four Data Centers with colocation services available. These are 777 Walker (2 Shell Plaza) in Houston, 1905 E. 6th Street in Austin, 2323 Bryan in Dallas and 307 & 309 West 7th St. in Fort Worth. The Austin and Houston data centers are SAS 70 Type II Audio Certified for critical operations that need to meet that requirement.

Colocation solutions include full and half cabinets, private cages, relay racks, flexible power configurations and the Alpheus Tier 1 regional fiber optic network with connections to over 75 carriers. “Remote Hands” service is a way to let Alpheus engineers perform simple troubleshooting and maintenance tasks, plus lend a hand when emergencies pop up. Remote Hands include server & equipment reboot, equipment and card testing, secure cabling connections and removal of customer equipment.

Is your business located in Texas and in need of connectivity or colocation services? There are excellent options available to you for a simple inquiry. Get competitive quotes from Alpheus and other top tier carriers for bandwidth services and equipment colocation and see what works best for your situation.

Microsoft Communication In The Integra Cloud

There’s no doubt that business communication is getting more sophisticated. A multi-line telephone and a FAX machine might have sufficed years ago. Now, email is so last century. If you want to be on top of the productivity curve, you need have collaboration and unified communications in your tool set.

Sounds great, but how are you set up to support all the latest business communication services? Larger enterprises have dedicated staff to handle hardware, software, mobility, VPNs and everything else needed to support their electronic communication needs. Small and medium size companies aren’t so flush. If they can afford the cost of the servers and software packages, they may well need to depend on outside consultants to get everything working together and fight fires as they pop up. Otherwise, it’s get by as best you can. Seems like there ought to be a better way.

The cloud may well be that better way. The idea of cloud communications is that all the intricacies involved in multi-media electronic communication is hidden from the user. The provider takes care of the servers, the software, the maintenance, the integration, the setup and the troubleshooting. As a user, you do just that: You use the service. When you have trouble or need some extra feature, you call the service provider and they take care of it for you. Because they specialize in the cloud services they are offering, they have the resources to handle everything efficiently. Instead of investing and operating, you simply use and pay by the month for each user you have on-board.

A powerful combination of service and provider is Microsoft Communication Services and Integra Telecom. You are no doubt familiar with Microsoft software such as Outlook, Exchange, Lync and SharePoint. Are you aware that these services have been integrated with Microsoft Office Communications Server as a bundled cloud-based resource? Have a look at this video for a quick introduction:



Have you been toying with the idea of Hosted Microsoft Exchange or Hosted Outlook because you really don’t want to run your own data center? Why not go with the whole package of Microsoft Communication Services and leap to the cutting edge in one fell swoop? By the time you factor in what it will cost you to do everything this suite of communication services does in a piecemeal fashion, you might as well go with the cloud service and a solid provider.

How do you find a good provider? Start with Integra Telecom. They are more than just a cloud service provider. They are actually a competitive telecommunications carrier that has expanded their domain to include cloud services as well as connectivity. With Integra you have one point of contact and all the expertise to ensure that the services work correctly, plus assurance that you are efficiently connected at all times.

Integra runs an 11 state fiber optic network with 1,900 fiber fed buildings and many more connected via Ethernet over Copper. They provide high bandwidth services to customers in Arizona, California, Colorado, Idaho, Minnesota, Montana, Nevada, North Dakota, Oregon, Utah and Washington. They offer a complete range of telecom services that includes business phone lines and trunks, hosted PBX services, private networking including MPLS VPN and private line services, high speed Internet access, server colocation and cloud-based collaboration and messaging.

Have you reached the limits of what you can afford to purchase or support, yet need the productivity improvements that come with the latest unified communications services? You may find that cloud hosted solutions can give you far more for your dollar than doing it all yourself. Before you give up in frustration, get a quick quote for cloud communications services scaled to the size of your business. You may be able to afford a lot more than you think.

Texas Fiber Optic Network Expansion

There are big things afoot in the Lone Star State. In this case, it's big network expansions from partnerships and mergers. The result is more options and fiber network availability for businesses located in Texas.

Transtelco is a major competitive provider with a fiber network that stretches from Houston to Los Angeles and dips into Northern Mexico to pick up Monterrey, Chihuahua, Nogales, and Tijuana. The have expansion plans for both Mexico and Texas routes.

Within Texas, PAETEC, another major competitive provider, has considerable fiber assets serving Dallas, Austin and Houston, to name a few of their Texas POPs (Points of Presence). PAETEC now has offices in Austin, Dallas, Fort Worth, Houston, San Antonio and The Woodlands.

What’s afoot is a joint venture between PAETEC and Transtelco that has PAETEC building out Transtelco’s fiber leg connecting El Paso and Temple. With half ownership in this project, PAETEC gains additional SONET ring diversity for its network across the southern US and into Mexico. They also have access to offer voice, Internet and fixed wireless to agencies of the state government that use services of the State of Texas Department of Information Resources.

What makes this situation even more interesting is that PAETEC has been acquired by Windstream Communication, a competitive carrier serving the southeast and midwest US, including fiber runs into Dallas, as well as a network that extends into Arkansas, Mississippi, Alabama, Georgia, Tennessee, Kentucky, Illinois, Iowa, Wisconsin, Minnesota, Michigan, Ohio, West Virginia and Virginia. Windstream has major fiber connections planned into other states, plus existing data centers in Newton, Iowa, Brookfield, Wisconsin, Nashville, Tennessee, Atlanta, Georgia, Jacksonville, Florida, Charlotte, Cary, and Raleigh North Carolina, Ephrata and State College, Pennsylvania and Boston, Massachusetts. Windstream’s existing fiber network spans some 60,000 route miles.

Windstream offers MPLS network services based on a resilient optical core to service companies with multiple business locations. Their network offers VPN (Virtual Private Network) with VLAN (Virtual Local Area Network) connectivity. It’s a fully meshed network that allows regional sites to exchange traffic without having to depend on a central hub server. For companies with converged voice and data networks, Windstream offers Real-Time QoS that ensures voice packets receive top priority to keep them from getting slowed down or held up by less sensitive data packets.

Do you need fast and reliable access to the Internet? Windstream offers Ethernet Internet with symmetrical bandwidth up to 1 Gbps.

OC-48 Pricing Reductions Make 2.5 Gbps Affordable

OC-48 bandwidth is a staple among regional Internet service providers and larger corporations. It forms the core or many fiber optic network backbones implemented as SONET rings over hundreds or even thousands of miles. Even with more availability than ever before, many businesses shy away from even considering this high bandwidth service in fear of the budget-busting sticker shock that they reasonably expect. It’s time to reconsider that decision.

OC-48 is one of the SONET (Synchronous Optical NETwork) standard service levels. These bandwidth levels pick up where T-carrier copper services leave off. DS3 or T3 lines provide 45 Mbps of transport. The equivalent OC or Optical Carrier level is OC-1 at 52 Mbps. OC-1 isn’t readily available as an actual line service. In practice the lowest level SONET fiber optic service is OC-3 at 155 Mbps. The next practical step up is OC-12 at 622 Mbps. In some areas you can get OC-24 at 1.25 Gbps, but a more popular level is OC-48 at 2.5 Gbps. Beyond that is OC-192 at 10 Gbps and OC-768 at 40 Gbps.

What makes OC-48 so popular? Many incumbent and competitive carriers constructed their fiber optic networks around OC-48, although some of the largest have moved on to OC-192 and OC-768. OC-48 is widely used for tributaries from OC-192 backbone nodes. Some newer fiber networks are built upon IP cores, completely bypassing legacy SONET technology. Many more are running MPLS or Ethernet over SONET.

One reason for this is that the SONET core is already in place, including all the routing and switching equipment. Another is that SONET is a proven technology that is widely supported and designed for carrier-class services. For instance, most SONET rings are dual rings that offer protection from fiber cuts and equipment failures. In the event of an outage, switching from one ring to another is accomplished in less than 50 mSec.

Once a technology that carriers kept for themselves, OC-48 pricing has dropped so much over the years that it is now a popular connection for many businesses. This includes large hospital and medical center networks, video producers, content delivery networks, broadband Internet service providers, computer aided design firms, businesses with substantial e-commerce activities, popular websites, and heavy users of cloud computing.

Cloud computing is something of a two-edged sword. The advantages include fast scaling of services up and down as your needs change, high reliability, and the ability to empty local data centers to avoid ongoing capital and operating expenses. What might get lost in the initial zeal to outsource to the cloud is how you connect with your new virtual data center located hundreds or thousands of miles away. All of a sudden, WAN connections that were perfectly adequate when most of the IT servers were still on the corporate campus are now sluggish and unresponsive.

If you want to maintain or regain that snappy performance that comes with high speed low latency dedicated private line connections, you’ll need to upgrade your connections between your headquarters and your cloud services providers. OC-48 fiber optic bandwidth may be just the ticket. At two and a half times Gigabit Ethernet bandwidth, you’ll have the capacity you need to avoid network congestion. With a protected service and SLA (service level agreement), you’ll have the reliable service you need for critical business operations. Finally, with recent price reductions from competitive service providers, you can now afford a level of service that previously seemed out of reach.

Have the requirements of your business increased because of business automation, new technologies such as video transport, or a move to the cloud? This is a good time to get a new set of lease prices for both Carrier Ethernet and SONET fiber optic services. High bandwidth circuits, such as OC-48, are now more affordable than ever before.

Metro Ethernet vs MPLS Networking

In addition to dedicated Internet access, many companies also need point to point private lines and/or multipoint network connections. The classic way to accomplish this has been to lease private lines to create your own wide area network setup. There are two other methods available that can give you the same results for considerably less cost.

Metro Ethernet service has been seen as a way to get point to point connections in town at a lower cost than leasing dedicated line services, such as DS3 or OC3. This service is called E-Line or Ethernet Line. It’s is standardized by the MEF (Metro Ethernet Forum) so you can compare E-Line services from multiple vendors and know that you are getting the same product.

What’s the difference between ordering an E-Line connection at 50 Mbps versus a DS3 dedicated line at 45 Mbps? When you order a dedicated line, you can envision having a pair of wires going from your headquarters, through a cross-connect at the telco central office and then out to your branch office. That’s probably true for a T1 line provisioned on two twisted copper pair. When you get into DS3 and higher bandwidths, your connection will probably be carried via SONET fiber optic service using an add/drop multiplexer. Along the way, your signal will be traveling with many other who share the same fiber strand.

Here’s what’s important: Unless you actually go out and construct or lease the copper or fiber transmission medium, you are using a shared or multi-tenant service. It’s true with Metro Ethernet and MPLS Networks. It’s also true with dedicated line services. The difference is that MPLS and Metro Ethernet are packet switched networks while T-Carrier and SONET services are circuit switched. With circuit switching, the circuit is used only for your traffic on a single path that is “nailed up” for the time you hold the lease. With packet switching, other traffic can share common paths through the network. That does two things. It lowers the price of the service and it makes some additional services possible.

Metro Ethernet has both an Ethernet Private Line and Ethernet Virtual Private Line service available. The virtualization means that you only need to install one Carrier Ethernet port to have connections with two or more locations. The actual physical line is shared among your own traffic. You may have ten or more branch offices, retail stores or other locations in town. With EVPL you can have point to point connections to many locations coming in through one UNI (User Network Interface).

Here’s another service you can get with Metro Ethernet. It’s called E-LAN or Ethernet LAN service. This is a meshed network that lets many locations all communicate without going through a single point. E-LAN is popular for interconnecting a company’s many independent LANs in the same geographical area. This can be done at the layer 2 level so that the entire network looks like one giant bridged network.

Interconnecting multiple locations is also the domain of MPLS or Multi-Protocol Label Switching networks. Many of these have regional, national or even international service footprints so that all of your far flung locations can interact on the same network. MPLS may be the solution of choice for covering geographical areas larger than a single city and its suburbs. MPLS can also be used to create point to point connections for only two locations. When those locations are located on opposite coasts or in different countries, MPLS can be a better deal than Ethernet Line service or point to point dedicated line services.

Since Ethernet and MPLS services overlap to some extent, what criteria do you use to make a choice? I’d recommend getting price quotes for these, plus dedicated lines, and comparing the total lease cost for the same bandwidth and other requirements. You can get networking bandwidth quotes from multiple service providers quickly and easily using the GeoQuote tool. In fact, many line services to 1 Gbps quote automatically online.

MPLS Point to Point Alternative

The traditional way to connect two business locations to send files back and forth is with a point to point data connection. T1 lines have been perfect for this at modest bandwidth levels. DS3 and OCx SONET services work the same way when higher speeds are needed. Ethernet line service is the latest entry into the Point to Point bandwidth space. But have you considered MPLS networks as your best value for the money?

MPLS may seem like an odd choice, since MPLS networks are really targeted for multi-point connectivity in place of older technologies like Frame Relay. MPLS networks are organized as clouds with multiple access points over the service footprint. If you have a dozen or a hundred locations to network, an MPLS solution is likely the best solution by a mile. Yet, there’s no reason you can’t just specify connecting point A to point B as your only connection.

The one possible downside might be cost. Whether a dedicated point to point line service or an MPLS network service makes sense for any given application depends a lot on the distance between locations and whether you intend to order more than one line. Why multiple lines? While some businesses have only two locations to connect, many others have three or more. The most expensive way to make multiple connections is by running point to point lines from each location to the others. A more cost effective approach is to set up a star network with the routing equipment at headquarters and point to point lines fanning out from there to each satellite location. The least cost most flexible solution is often to simply connect every location to a regional or national MPLS network and specify the connectivity within the cloud.

T1 point to point lines became popular because they are relatively inexpensive and offer the security and performance of a dedicated line. You have exclusive use of the 1.5 Mbps bandwidth in both directions. Since the line is “nailed up” to interconnect two locations, security is high. It’s difficult to impossible for snoops and troublemakers to gain access to your private line.

One disadvantage of using dedicated T1 lines is that you are limited to 1.5 Mbps per line, although you can often bond T1 lines together to multiply the bandwidth up to a maximum of 10 or 12 Mbps. Another drawback is that there is no economy of scale. Two lines cost twice as much as one line. They also tend to be priced by distance. A point to point line in town costs much less than a connection from coast to coast. If you need to cross an ocean or international border the cost goes up significantly.

Everything that has been said about T1 lines also goes for higher bandwidth options, such as DS3, OC3, and so on. The cost increases along with bandwidth. Ethernet over Copper or Ethernet over Fiber offers higher bandwidth at lower prices, but is also a dedicated line service. It’s the protocol that’s different between T1 or SONET and Ethernet services.

MPLS networks have a different cost model. The network is based on a privately owned high speed national or international fiber optic network. None of the core network is dedicated to a single customer. It is intended to be shared among many customers to amortize the cost. As such, the cost of a point to point or multipoint connection is more attractive than for a dedicated line service. In-town or close by, the dedicated line may be the cheaper solution. But for locations spaced thousands of miles apart or overseas, MPLS networks have the advantage.

What makes MPLS networks a good substitute for dedicated point to point lines is that the network offers security and guaranteed performance as well as a cost savings. The proprietary nature of the label switching protocol and the fact that access is limited to customers of the network make security much higher than on a public network like the Internet. The network operators establish the virtual paths through the network on a case by case basis. You may be sharing the fiber strands, but you can’t access another customer’s data and they can’t see yours.

Do you have a requirement to link business locations? Be sure to get MPLS network service pricing as well as dedicated line pricing for even a two location hookup to make sure you have the best deal.

Low Latency Fiber Network For Orange County

Businesses are demanding more bandwidth at lower latencies to support demanding applications such as financial trading, business process automation, cloud computing & storage and medical image transmission. This is creating an opportunity for new fiber buildout, like the one underway in the Los Angeles Metro area.

AboveNet, a major provider of fiber optic networking services in the US and Europe, is launching what they call a large “feeder ring” to connect office buildings, data centers, and carrier hotels to an existing fiber optic backbone that now serves the business districts of Irvine and Costa Mesa in Orange County, California.

Fiber optic connectivity has become the new battleground for competitive service providers as well as incumbent telcos. A major push has been the transition from legacy SONET/SDH to Gigabit Ethernet, 10 GigE and 40 GigE, MPLS networks, dark fiber and wavelength services. Networks are becoming more IP oriented, at the expense of traditional switched circuit TDM technologies. This plays well with the dominance of Ethernet networks in business and the move to converged voice, data and video networks.

Cloud services have opened up a further need for increased bandwidth. When companies had on-site data centers for their servers and storage, most traffic was contained within the building or campus LAN. Special links served overnight tape backup at offsite storage centers. Once computing and disk resources move to a colocation facility or a cloud services provider, there is a corresponding increase in WAN bandwidth requirements. With everything “out there,” a much higher portion of traffic leaves the company LAN.

AboveNet and other carriers are in a major push right now to expand their fiber optic network footprints in the US and abroad. Especially important are low latency networks to Europe and Asia to interconnect financial markets and major international businesses. Private networks require an enormous capital investment and the Internet is unsuitable for high performance, secure connections. That’s creating an opportunity for companies that specialize in metro and long haul fiber optic networks to jump in and fill the need.

Some services that are seeing more demand are IP transit to connect with the Internet backbone for companies that don’t have networks large enough to do their own peering, Ethernet Private Line and LAN services, global MPLS networking, and wavelength services that offer both very high bandwidth capacity along with flexibility of protocols.

Competitive pressures have also reduced the cost per Mbps for nearly all leased line services. This is true for even the ubiquitous T1 lines, but even more so for Ethernet connections of all types. Ethernet availability has expanded to such an extent that it is often far less expensive than T-Carrier or SONET in most metro areas. Gigabit Ethernet and 10 GigE WAN connections are now routinely ordered by larger business and organizations.

Is your company bandwidth starved or simply looking for better prices on existing network services? See if you can do better by checking prices and availability for fiber optic bandwidth.

Ethernet Point of Presence Locator

You’ve been hearing about lower cost bandwidth options and wondering if you can get more Mbps for less money. The question is, “how can you find out?” What you need is an Ethernet Point of Presence Locator.

What’s that and what’s a point of presence? Ah, these are the keys to getting a better deal on business bandwidth.



Point of Presence, or POP, is a location where carrier services are located. For instance, a major competitive carrier may well have a central office located in your city. Within this facility is termination equipment for the carrier’s metropolitan and long haul fiber optic network. In other words, this carrier POP is like a station where you can get on and off their high speed voice and data network.

The same carrier may have POPs that aren’t part of their office facilities. Many carriers have POPs within colocation centers. Those are public facilities that specialize in housing server equipment for business users. They offer rack space, security, fire suppression, back up power and bandwidth. The bandwidth is provided by however many carriers choose to establish carrier POPs in the colo facility. Because your equipment is located within feet of the carrier POP, construction costs to provide you with bandwidth are little to nothing.

So, you’re looking around and don’t see any colocation centers or carrier central offices anywhere near your building. Does that mean that you are out of luck? No, not at all. There may be all sorts of POPs that aren’t readily apparent. The most prevalent example is the “lit” building. Lit means lit for fiber optic services. To light a building, fiber optic cabling and termination equipment must be installed and turned up. That’s generally only done when there is enough demand by one or more clients in the building for high bandwidth services. But once a building is lit, it can be used as a jumping off point to provide services to other buildings nearby.

The beauty of finding a lit building and its associated Point of Presence is that construction costs are minimal if you are next door to such a facility or within a short distance. The big cost of providing fiber optic bandwidth services is having to trench the fiber cable underground or suspend it overhead on utility poles for miles and miles. Bandwidth, especially Ethernet bandwidth, can be quite affordable if you don’t have to bear the capital expense of extensive fiber construction.

So, if they are not visible to the naked eye, how do you find these lit buildings? Fortunately, you have access to the Ethernet Building’s Point of Presence Locator. You simply enter the address of your building and get a map of nearby lit buildings in seconds. You can then get prices for bandwidth services you are interested in. It’s quick and easy, so give it a try. You may be surprised by how much fiber optic capability is hiding right next door or down the street.

Many Wavelengths to Serve You

What happens when you max out the capacity of your network but still need more bandwidth? You have to go with a faster network, right? You may have to go with faster NIC (Network Interface Cards) and Ethernet switches for every node. What you don't want to do is run out of capacity on your lines. When you've got all you are going to get out of your structured wiring system, it gets expensive, really expensive, to upgrade that network. But what if you could just add some more signals into those same cables and multiply the bandwidth 32 or even 160 times? If your network is fiber optic based, you can do just that.

The magic is in a process called WDM or Wavelength Division Multiplexing. We think of fiber optic networks as having a beam of light at one end and a receiver at the other. The transmission electronics modulates a laser beam with our data stream and a photodiode at the other end converts the modulated light back into electrical pulses. What WDM does is send multiple beams down the same fiber optic cable in parallel. Two beams gives you 2x the capacity, four beams gives 4x, and so on. This process is so well developed that you can send 16 to 160 separate beams simultaneously to support enormous bandwidths.

Fiber optic networks are much faster than copper-based networks to begin with. Gigabit Ethernet over copper can be a challenge within an office environment. Forget long haul. T3 is the highest of the copper T-Carrier systems at 45 Mbps and is usually only deployed over a few miles. T1 lines can reach out to just about any distance using regenerators, but the bandwidth is limited to 1.5 Mbps. Compare that to typical long haul fiber bandwidths of OC-48 at 2.5 Gbps or OC-192 at 10 Gbps. Some carriers are upgrading their core rates to the OC-768 level of 40 Gbps.

In the world of copper transmission lines, frequency division multiplexing (FDM) is the equivalent of fiber optic WDM. FDM is what Cable TV companies use. Each channel has its own carrier and occupies its own narrow band of frequencies in the spectrum. More than 100 standard TV channels of 6 MHz each can be carried on a typical cable system. Some of these channels are assigned to broadband Internet services rather than television transmissions.

Wavelengths are also different frequencies which, in the optical (including infrared) parts the spectrum, represent different colors. They are also called lambdas after the Greek letter representing wavelength. Light split from a prism demonstrates that many different colors can exist simultaneously in a single beam without interference.

There a two general categories of WDM. CWDM or Coarse Wavelength Division Multiplexing uses up to 16 different wavelengths within an individual single mode fiber strand. DWDM or Dense Wavelength Division Multiplexing uses up to 160 wavelengths in a fiber strand and requires more precisely controlled lasers. But at 10 Gbps capacity per wavelength, a system with 160 wavelengths offers well over a Terabit/second bandwidth.

WDM schemes are found in long haul carrier core networks where the cost of installing hundreds or thousands of miles of fiber optic cable far exceeds the cost of new electronics to increase capacity by adding more wavelengths on the same fiber. WDM or CWDM is also installed on dark fiber when customers need the extra capacity in metropolitan (MAN) networks.

Thanks to WDM and competitive carrier build-outs, fiber optic bandwidth is more affordable than ever. That's especially true for the new Ethernet over fiber services available to businesses in major metropolitan areas.

XO Communications Nears Tbps National Network

If there is any doubt in your mind that the widely discussed bandwidth glut of the great telecom boom in the late 90's has all but evaporated, this news should make it clear. XO communications is implementing an upgrade of its national backbone that was just upgraded last year. The core fiber bandwidth is being extended from 400 Gbps to 800 Gbps on major coast to coast network routes. Just another 200 Gbps and we're talking Terabit/second bandwidth.

Is near-Tbps bandwidth really needed? Apparently so. XO cites a 5x increase in orders for high capacity inter-city network transport services within the last year. Inter-city and metro transport demands are coming from telecom carriers, cable companies, content providers, large enterprises and wireless companies. These major users will then deploy that bandwidth in smaller fractions to serve B2B and B2C applications, including connectivity to branch offices and SMBs (small to medium size businesses). Applications such as VoIP, HD video, video streaming, rich multimedia content, and faster broadband Internet services all sop up bandwidth at a prodigious rate. A Gigabit per second just isn't the cornucopia it used to be.

XO is being smart about their implementation. The plan is to light two new fiber strands using the Infinera DTN system that was deployed last year as part of the network upgrade to 400 Gbps. The 800 Gbps will be organized as 80 10-Gbps channels running over 18,000 route-miles of the nationwide network. XO's inter-city network currently connects 75 major metropolitan areas across the United States.

Fiber optic services offered by XO include Ethernet from GigE to 10 Gbps, IP transit and private line services from OC-3 to OC-192 and wavelength services at 2.5 Gbps and 10 Gbps speeds. XO also offers a complete suite of business services, with over 3,000 fiber-fed buildings on net, plus copper and wireless connectivity including traditional T1 voice and data services. Beyond connectivity, XO offers managed firewalls, VPNs and server collocation hosting.
