Can Satellite Be Part of Your SD-WAN?

By: John Shepler

Software Defined Networks (SDN) or Software Defined Wide Area Networks (SD-WAN) are being implemented more and more to provide high quality business bandwidth at lower costs. In some cases, SD-WAN is the only way to get decent bandwidth levels in rural and remote areas. You might think of these software defined networks as a potpourri of different connection technologies, but it’s more than that. it’s an intelligent approach to making the most of every connection available, including satellite.

Consider satellite as part of your SD-WAN solutionWhy The Need For SD Networks
Say you want to connect to the Internet or to your cloud service provider. Traditionally, you’ve done that by ordering up a “last mile” connection from your business location to the Internet or a private point to point line between two locations, such as your office and your cloud provider.

That’s great as long as there are providers who can give you all the bandwidth you need and at a price that won’t choke your business. The problem is that you often overpay for premium bandwidth that goes unused or settle for what the budget can handle and regret the performance limitations every day.

In reality, different tasks have different connection requirements. Telephone lines for a call center or even ordinary office use don’t need tremendous amounts of bandwidth but are highly sensitive to latency, jitter and packet loss. Backing up files to a remote data center or storage in the cloud is fairly insensitive to the latency, jitter and packet loss characteristics but needs lots of bandwidth to get done in a reasonable time.

This is where SDN / SD-WAN work their magic. An intelligent processor acts as a traffic manager for each and every packet entering the network. Those voice packets get routed to a dedicated high performance but limited bandwidth circuit like like a T1 or ISDN PRI. File backups can go via cable broadband or as lower priority on the T1 or fiber optic line. Business applications in the cloud need reliability and quick response. They’ll go over a high performance connection.

How SD Networks Optimize Cost
The processing power within the SDN controller makes note of what each type of traffic needs. You’ve told it that. The processor is also constantly monitoring the status of each connection that you’ve provided it. It can truly be a potpourri of T1, DS3, cable broadband, 4G and 5G wireless, Point to Point Microwave, Ethernet over Copper, Ethernet over Fiber, SONET, MPLS networks, DSL, and two-way Satellite.

What’s key is that the controller knows at each instant how each connection is performing. Low cost connections aren’t always low performing. That DSL or cable link might be zooming along right now. The low cost usually comes from these being shared rather than dedicated connections. Other users, not in your company, can be hogging bandwidth and creating congestion to slow you down.

Satellite may well have excellent speed and low packet loss. The geosynchronous satellites now in service do have long latency times that can’t be avoided. That can be an issue with voice and video conversations, but makes little difference for file transfers or downloaded video.

Wireless connections in general have usage limits simply because wireless bandwidth is a scarce resource. SDN needs to be mindful of that in assigning the connections to avoid bandwidth slowdowns or additional charges.

The point is that you don’t need to buy the most expensive bandwidth solution in many cases. You won’t be able to load up that line 100% of the time with traffic that absolutely needs it. SDN / SD-WAN can ensure that your costly connections get used to the max but offload traffic that doesn’t need such high performance to a lower cost link. You also gain the advantage of automatic failover in case one of your links fails.

When Availability Is Most Important
There are many locations in rural America where you can stand outside and waive a fist full of money to buy connectivity and have no takers. This is where an SD network solution can really help. The newer high bandwidth satellites offer fast speeds and quality connections. You can include a dedicated SIP trunk based on a T1 line for your VoIP phone calls to get around the latency issue. it is likely that cellular broadband is also available in most areas. Combine these and you may well get all the bandwidth you need with the performance you also need without having to pay a fortune to bring in a fiber cable… if anyone will even do it.

Are you frustrated with either the cost of connectivity or its availability? This would be a good time to look into SDN / SD-WAN solutions that can give you the performance you need at a cost you can afford.

Dedicated Symmetric Internet Connections

By: John Shepler

Are you frustrated with the performance of the Internet for business use? Are you inclined to think that the entire thing is really more intended for entertainment and casual browsing that actually getting work done in a timely fashion? Yet, there’s really no alternative. Your customers and suppliers and all the information you need is online. Even your software packages and communications may be on the cloud now. Perhaps all you really need is a higher performance broadband connection that is more suited to the workplace.

Get high speed dedicated symmetric Internet access now.What’s Wrong With My Internet Service?
Chances are that your Internet Service Provider is delivering the service you ordered exactly as advertised.There is nothing really wrong with it. It’s just that the particular connection you are using is not up to the job. That’s especially true if you are making demands beyond what the typical Internet user expects. Some of the key parameters you need to be aware of include bandwidth, symmetry, dedication, latency, jitter, and packet loss. Let’s take those one at a time and see why they make a difference.

Bandwidth
Do fire fighters try to put out a blazing building with a garden hose? Of course not. A small pipe can’t deliver the huge volume of water needed. Same with bandwidth. A small or low bandwidth connection might keep up with emails, credit card verification, casual browsing and some video streaming. it can’t keep a dozen, a hundred or a thousand employees working efficiently. Once the “pipe” (yes, it’s actually called that) is at capacity you experience congestion. Too many packets per unit of time. Somebody has to wait their turn… and wait, and wait and wait.

You need bandwidth appropriate to the job. That means you’ll have to kiss DSL goodbye. T1 lines are reliable but way too slow these days. Same for budget cable broadband, 3G or even 4G wireless. Move up to fiber optic service if you can possibly get it without too much construction cost. Otherwise, Ethernet over Copper may work. Depending on the application, you might get by with 100 Mbps to 1000 Gbps DOCSIS cable.

Symmetry
Not all broadband is the same by a long shot. One big difference is symmetry of upload and download bandwidth. Symmetry means how much alike they are. Cable, satellite, DSL and similar connections that primarily serve the consumer market are not symmetrical. They are called asymmetrical. You may get 100 Mbps in the download direction but only 10 Mbps in the upload direction.

What difference does it make? Consumers don’t care. They mostly download. Businesses transfer large files between locations and upload them to remote web servers. Enterprise software packages transfer data in both directions. Offsite backups are primarily in the upload direction. If you can watch videos easily but can’t backup your files, you’ve got a symmetry problem.

Dedication
We’re all dedicated to the job, right? That’s not what this is about. The two choices in bandwidth are dedicated and shared. Once again, those low cost broadband services are actually shared bandwidth. You and a dozen or a hundred other customers are all drinking from the same pipe. When everybody wants service at the same time, there isn’t enough to go around and things slow down. It’s really bad when they slow down during business hours and worse when you are working to a deadline.

Dedicated bandwidth services are yours and yours alone. Don’t get me wrong. The Internet backbones themselves are always shared. That’s not where the problem usually is. The real pinch point is that last mile between you and your service provider. You want that to be a dedicated connection if you expect consistency high performance.

Latency
Latency is a time delay. It’s a pause. Every circuit has latency. Even your local area network has some. The trick is to keep the latency so low you don’t notice it. What adds latency? Long distance connections with lots of equipment on the line. The worst is geostationary satellites. No matter what you do, there’s a half-second or more of time delay between action and response. Ten milliseconds of latency likely won’t hurt anybody. A hundred milliseconds will probably be noticeable. Half a second to a second? Maddening. Real time services such as VoIP telephone and video conferencing will be the most affected. If you need to use a satellite, be prepared to pause to let the other person speak or you’ll talk all over each other.

Jitter and Packet Loss
Jitter is a variation in arrival between packets. It’s another congestion problem. Jitter distorts conversations. Worse is packet loss. That means some packets get sent and never received. Data transfer protocols will simply request a resend. Voice and video will have holes in the stream that add more distortion. If packet loss is too bad due to a nearly unusable connection, even website performance and data backups will slow to a crawl.

Dedicated Symmetric Internet Connections
The gold standard in professional grade business Internet service is dedicated symmetric lines. Even better are dedicated symmetric lines that go directly from location to location, like branch offices or to a cloud service, and avoid the Internet altogether. If you are going to use the Internet, though, give yourself the best performance possible. Insist on a dedicated symmetric Internet access, preferably with a service level agreement. Plan on paying considerably more than you will for a budget connection, but consider it worth the price in productivity and better customer relations.

WANs That Act Like LANs

We take our Local Area Networks (LANs) for granted. Every business has them, but they are seldom seen except for that network connector on the wall. You plug-in your computer, printer, phone, etc. and it just works.

Find better Wide Area Network Connections now!Networks vs Utilities
In a way, LANs are now the data equivalent of AC power. You don’t think about it. You just use it. Connections and operations were long ago standardized. You don’t worry about different flavors of Ethernet any more than you stop and think what voltage is coming out of that wall socket.

Now, how about those Wide Area Networks (WANs)? It’s the WAN that gets you out of the building and connected to your other business locations, your cloud services and everyone else in the world. We don’t think about the fact that electrical power is transformed to higher voltages and that there are switching centers between your location and the power generation. It’s just as invisible as the wires running through the walls. If only Wide Area Networks worked the same way (sigh!)

The Difference Between LANs and WANs
The big difference between local and metro or wide area networks is that the local nets tend to be invisible and the longer haul connections may not be. You probably don’t have to be concerned about bandwidth, jitter, latency or packet loss on an in-house network. Wired LANs, especially, do a good job of keeping these issues out of your way. As you leave the premises, those characteristics degrade. Ideally it is not enough to get in your way, but sometimes it’s a major stumbling block.

Where WANs Go Bad
Take the most common WAN we use: The Internet. The Internet is an amazing infrastructure that connects nearly everyone to everyone else. It was designed from the beginning to be extremely robust, so that line cuts and equipment outages are automatically worked around. Its design philosophy and popularity are its limitations. The speed and quality of your connection can vary from minute to minute depending on traffic levels. The least costly connections, like cable and cellular, are shared, increasing the variability even more.

Invisible WANs
If you want the same performance over long distances that you have in-house, you need to order dedicated symmetrical wired, wireless and fiber point-to-point or multipoint services. Yes, a dedicated connection will help Internet performance greatly because most of the issues are in the “last mile” connection to your facility. Dedicated direct lines may make a huge difference in how business critical systems like VoIP telephone and software as a service in the cloud perform. MPLS networks provide similar high performance among multiple business locations, including remote data centers and cloud service providers.

The Almost Invisible WAN
The one sore point with dedicated lines is that can be a bit pricey, especially if you need a lot of bandwidth over very long distances. It’s a cost/benefit tradeoff. Dedicated wins for most medium and larger size businesses, where productivity losses and poor quality voice services are intolerable.

For smaller businesses and less critical applications, however, there is a fairly new alternative that makes the Internet perform more like a direct connection. This is called SDN or Software Defined Network, sometimes also referred to as a SD-WAN or Software Defined Wide Area Network. What the software does is combine multiple lower performing connections to produce a composite service that works much better. The SD-WAN monitors each WAN connection packet-by-packet and routes the most critical packets over the best performing links at that instant. It goes a long way toward making very noticeable Internet services more like invisible direct connections.

Are you frustrated by unacceptably poor Internet or other WAN services or have just hit the limit of your current bandwidth? Discover the range of competitive Wide Are Network connections that are now available for your business locations.

Are Your WAN Circuits Monitored For Quality?

By: John Shepler

As we transition from circuit switched telephony and make the move from in-house data centers to the cloud, our WAN (Wide Area Network) circuits become more critical than ever before. A misbehaving network connection that might once have been a mere inconvenience is now a productivity killer at best and a business shutdown at worst. It is essential that every copper and fiber optic line that leaves the building be running at peak performance all the time. But… how do you make sure that is the case?

Are you WAN Circuits monitored?Do You Know What is Going On Behind Your Back?
Technology has a sneaky side. When your outside network circuits are installed and checked out, the lines are verified to make sure they meet specs for latency, packet loss, jitter and bandwidth. Everything is running great. Tomorrow it’s still running great. But the next day, next week or next month something goes wrong. it might be a subtle change that degrades performance rather than knocking the line out completely.

Where do you point the finger?
The problem could be anywhere in the system. Is your LAN congested or are you dealing with a failing switch? Is it just your computer or telephone set that is having problems? Perhaps it is one of several network circuits that connect you to the outside world. How do you find out for sure?

Circuit Monitoring Is Your Eye on the Network
You can’t just blindly trust that everything is running smoothly. You need a way to look into the system. Likely, you already have that capability. You can run Ping and Traceroute diagnostic tests from your computer whenever you want. That’s great for troubleshooting if you know there is a problem and have time to sit down and run the tests. But what happens when no one is running diagnostics? Hard to say.

That’s where continuous circuit monitoring shines. You don’t have to jump in and run some tests. They are running all the time. Better yet, a monitoring program gives you a chart of how the circuit has been performing over time. Run a diagnostic yourself and you have only a single data point.

Get Automatic Heads-Up Messages
The other beauty of automating the performance monitoring of your WAN circuits is that the monitor can let you know when something goes out of whack. You can get an email when something goes wrong. That way, you don’t have to sit there and watch the screen continuously just in case there is an anomaly. You’ll get notified 24/7. The monitor never sleeps.

Best Deal Ever: Free Circuit Monitoring
The best way to get your WAN circuits monitored is to have it done for free. Ever hear of this? Probably not. This is a fairly new service powered by VXSuite and offered by Telarus on Internet and coax circuits with static IP addresses that they provide. MPLS and other monitoring is available. Telarus is well known for the extensive suite of carriers that they partner with and the best prices on WAN circuits. Now you get this bonus of free circuit monitoring included on both domestic and international circuits.

This circuit monitoring includes a ping and traceroute to that circuit. Packet loss and latency are also measured. If the circuit goes down, you get an email. You also have access to a web-based dashboard to view your current circuit status and performance graphics. A monthly email report is available if you wish.

Do you need WAN circuits you can depend on? Would you like those circuits to be monitored with the powerful VXSuite tools at no extra cost? If so, it is time to get the latest competitive pricing and availability of monitored WAN network circuits for your business.

Big Data Needs Big Bandwidth

By: John Shepler

Bandwidth levels are growing almost exponentially. One of the major infrastructure build-outs underway is a move to 100 Gbps or 100 GigE wavelength service on cross-country and international routes. It seems that Gigabit Ethernet was introduced only a few years ago and thought impractical for all but the most demanding business applications. Now GigE is almost considered entry level in some quarters. What could possibly be behind this massive increase in bandwidth demand?

Big Data On Board warning signs. Check 'em outIt All Started With Video
It is said that most of the world’s Internet traffic is now video. That’s right, not telephone calls, not file transfers, not even big graphics. Video alone is sucking up as much bandwidth as it can get. That’s not likely to change, either. SD video has migrated to HD video and 4K video is well on the way. How soon will the marketplace demand 8K video across the board?

Every increase in pixel density cranks up the bandwidth requirement to transport high quality images. Compression can help a great deal, but there’s a tradeoff between picture quality and depth of compression. Broadcasters and video producers really want to transport uncompressed video and leave the compression artifacts to be dealt with in the final link to the consumer.

Send In The Clouds
When cloud services meant taking all night to back up the day's files as a contingency to local storage, bandwidth levels weren’t too demanding. That’s all changed. The cloud is no longer just a non-critical backup service. It’s the main data center for many companies.

What’s sometimes forgotten is that your WAN (Wide Area Network) bandwidth becomes far more critical when key processes move to the cloud. Networking is much easier and cheaper when you’re talking about hundreds of feet within your own facilities. When you have to take that same flood of traffic and send it over a common carrier to get to your remote data center or cloud provider, line demands go way up. Remember, the WAN used to be just to link facilities and for communication with the outside world. Now it’s the main artery for everything you do.

What that means is that WAN bandwidth demands jump by 10, 100 or 1000 times. Other characteristics, like jitter, latency and packet loss, become huge factors in how well your cloud processes perform. If you scrimp in any of these areas, you may find yourself frustrated by underperforming processes and even losing productivity instead of gaining efficiency.

You Think the Internet of People Is Demanding?
Online business applications are generating more and more interesting and potentially useful data. Mobile apps with location services fall into this category. Pretty much anything that you do online has some potential value in customizing services or creating statistical data to improve marketing. That’s a flood of data that has to be handled by wireless and fiber connections.

Human generated big data is nothing compared to what we’ll be dealing with when the Internet of Things (IoT) gets rolling. For every person online, there will be dozens, hundreds or even thousands of “things” chatting wildly and generating volumes of data that would be useful if it could only get where it can be analyzed and put to use. That’s going to multiply the load on every communications channel.

Will they be able to handle it? Not with yesterday’s creaky links. Everything will need an upgrade. It’s in process now. Wireless channels are being expanded as fast as they can be rounded up and auctioned. Current 4G standards will become 5G and then 6G before you know it. But, what about terrestrial lines?

Fortunately, the bandwidth of fiber optic cables is nearly limitless from our current point of view. The 1 to 10 Gbps or so capacity of each strand can be multiplied by multiplexing dozens to hundreds of wavelengths. Wavelengths can be aggregated to create larger services of 100 Gbps and beyond. The build buildout now is 100 Gbps. Soon that will be 400 Gbps and then 1 Tbps, and it will happen sooner that we think.

Is yesterday’s bandwidth keeping you from becoming tomorrow’s high performance company? You should know that bandwidth prices have been falling almost as fast as demand has been increasing. The bandwidth upgrade you need may fit well within your budget. Want to find out? Get prices and availability on high performance fiber optic bandwidth services now.

The Cloud Needs Low Latency

By: John Shepler

It makes so much economic sense. Instead of getting a bank loan and making a major capital investment in your own server farm and data center, you simply contract with a cloud service provider and pay only for what you use when you use it. No more having to predict how business will be next year or even next quarter. You can roll with the punches with on-demand cloud services.

Cloud Computing Data Mouse Pad. Get one for yourself now.It Seems So Easy
The solution is deceptively simple. Clean out your current data center or don’t build one in the first place. Rent what you need from one of a myriad of cloud service providers. All you need is a simple link from your facilities to theirs and nobody on the network will know the difference. After all, how can they tell whether the servers are down the hall or across the country? Few users do anything but run the applications anyway.

The Hesitating Network
There’s an old saying that goes something like this: “On the network, the printer on the other side of the country is as close as the one in the next office.”

That’s an ideal. In reality it can either seem just that close or really a thousand miles away. The server three states over works the same as the one in the basement used to. Somehow, though, it’s developed a hesitation. You have to wait for the system to respond now. Worse, yet, that hesitation seems to vary. You really don’t know how the system is going to perform from one day to the next.

The Infinite Cloud That Isn’t
One used to be able to blame system performance lags on lack of resources. When everyone is running big jobs at the same time things slow down a bit. If you were clever, you tried to get your work done at odd hours before the thundering herd got to work or when they went to lunch. Let somebody else deal with the congestion. It’s the equivalent of drive-time traffic and no more fun.

That was one thing the cloud was supposed to fix. A major benefit of cloud data centers is that they have massive resources. Any given tenant can expand or contract the number of servers and the amount of storage they are using in real time. You aren’t supposed to run out of capacity ever. Yet, it seems like the cloud has less capability than you had before. How can that be possible?

The WAN Gotcha
One big thing that is often forgotten is that the printer in the next office and the one across the country have to be connected by something. That something is your WAN network connection. When all of your network resources were sitting on the LAN, the point was moot. There was plenty of capacity and the links were short enough that network performance just wasn’t an issue. You might say that the network became “transparent.”

Now, your network includes both the sporty LAN and metro and wide area connections that can be anything but sporty. In fact, they can be downright sluggish. That’s because there’s a difference between your local networks and the ones that run by telecom carriers. Local networks can be fairly easily engineered to have enough performance to appear transparent. That’s both harder and more expensive to do over long distances.

What’s Holding Back the WAN?
There are a few technical characteristics that spell the difference between transparent and not so transparent connections. These include bandwidth, latency, jitter and packet loss. You want to maximize the first and minimize the other three.

It’s tempting to jump to the conclusion that sluggish network performance is a result of too little capacity. When you start to use most of the available bandwidth most of the time, you can have periods of congestion where there are just too many packets to send down the line at the same time. Easy solution? Increase bandwidth. A double, triple or 10x bandwidth increase should solve the problem immediately… or will it?

One issue that no bandwidth increase can fix is latency. This is a time delay for packets to traverse the network. We think of electrical transmission being instantaneous from source to destination. At the local level, that’s a really good assumption. Once you leave the premises, though, even the speed of light may not be fast enough.

Minimizing Latency
Clearly, one way to minimize the time delay of transmission is to minimize the distance involved. Even at light speed, you can only go 186 miles in a millisecond. That’s 10 mSec for 1,860 miles. In fact, even that isn’t really possible. In real world glass fiber, you may be looking at more like 15 to 20 milliseconds one way or at least 40 milliseconds round trip. If you happen to be using a geosynchronous satellite link for part of the trip, that expands to a quarter to half a second.

Most applications aren’t going to be impacted by a 40+ millisecond delay, although half a second is definitely going to be noticeable and perhaps difficult to live with. This argues for using a terrestrial fiber link to the cloud (which is actually on the ground) and using the shortest path possible. A point to point dedicated private line is most likely the highest performance you can achieve. You may be able to get equivalent or nearly equivalent performance through a privately run MPLS network at a lower cost.

How About The Internet
Oh, yes, the Internet. It sounds like the ideal resource. It goes everywhere and connects everyone. The cost is amortized over so many users that the Internet is going to be your low cost solution. Security is certainly an issue, but encryption can create tunnels that give you a virtually private network that emulates a truly private network.

That emulation may fall short, not for security reasons, but in performance. The Internet is not engineered to minimize latency or jitter. It’s architecture is designed for resilience. If you lose a connection between servers, the network will automatically reconfigure to heal itself and keep the traffic moving. Unfortunately, that means your packets may take different paths on different trips. They may also encounter bottlenecks if particular nodes get overloaded.

Does this mean you can’t use the Internet to connect to the cloud? For maximum performance or highly sensitive interactive and real-time applications, you’ll do better with private lines. Otherwise, you might be satisfied with a private/public hybrid called DIA or Dedicated Internet Access. You still share the high performance backbone of the Internet core, but you connect via a private line that minimizes latency, jitter and packet loss during that critical first mile.

Finding a Better Cloud Connection
There is a range of cloud connectivity options available for most business locations. You should look at the cost/performance tradeoffs involved with each of these and then choose the link you need to make your connection to the cloud as transparent as you need.

The Value of Low Latency Fiber Optic Connections

By: John Shepler

If you are frustrated with your network performance, especially those connections going to the Internet or other business locations, you may be suffering from a latency related problem. Let’s take a quick look at achieving lower latency network connections for businesses and organizations:


When you are involved in very demanding applications where maximizing network performance is critical to success, such as high frequency financial trading, it’s clear that you need to focus on minimizing latency. Some companies have gone so far as to co-locate in the same facility as the stock exchanges to be a matter of feet rather than miles from the servers.

Most applications are nowhere near that demanding, but do require some attention to bandwidth, latency, packet loss and jitter. These are areas where private lines and MPLS networks shine and the Internet doesn’t do so well. Revisions to the network neutrality doctrine might, and I emphasize might, offer some performance increase for the Internet. That will be done by giving some traffic priority over other traffic.

Still, if you want to take control of your destiny, you need control of all of your network connections and you’ll only get that with services that you own or can lease with strict performance guarantees.

What common applications are highly sensitive to latency issues? Anything real time certainly is. That includes VoIP telephone systems, any network voice services, teleconferencing and telepresence.

Slightly more tolerant are interactive services that are not strictly real time. Think cloud servers. You issue commands or requests and the server sends back responses. Delays in cloud server response have come as a shock to some companies that thought they would get more performance, not less, when they moved from local data centers to the cloud. After all, cloud resources are virtually infinite, aren’t they? Even if they are, you’ve got to take the link between you and the cloud into consideration. Any latency caused by limited bandwidth, network congestion or equipment induced time delays are going to show up as an unexpected pause in data going up and down between you and the cloud.

If you upgrade to higher performance network connections, will your latency problems go away? Not unless you also manage your local network to minimize latency on critical applications. You’ll need multiple classes of service so that voice packets get priority and interactive cloud packets are next in line. Big data transfers, email, downloading videos and even casual Web browsing have to take a lower priority and they generally can. Companies that are just implementing enterprise VoIP to replace old-school analog phones are more likely to run into these issues than those who have worked the bugs out of their networks over the years.

What class of network connection service is optimum for your needs? There are a wide variety of private and public connections, each with a particular performance and price tag. Why not get a fresh set of low latency bandwidth quotes available at your business locations. This service is fast and the cost can be lower than you expect.

How Fiber Optic Metro Ethernet Works

By: John Shepler

Are you paying a small fortune for all the lines you need to connect your multiple business locations? Would you like more flexibility in scaling bandwidth when needed along with guaranteed dedicated bandwidth that is low in latency, jitter and packet loss? You may be missing out by not using this important network connection service. Let’s have a look at a what fiber optic Metro Ethernet connections can do for your business:


Did you notice the big cost advantage in having one service provider in charge of the core network and the last mile connections to each location? Major Metro Ethernet providers have this capability and can offer you a cost savings by using their facilities rather than having to lease portions of the links from the local telephone company.

There are also network services available that aren’t offered by legacy SONET/SDH connections. Most useful is probably Ethernet LAN service. This standardized Carrier Ethernet service creates a fully meshed layer 2 bridge LAN that ties together the in-house networks at each location. Employees perceive that they are all on the same network regardless of where they are located.

This would be a good time to learn more about Ethernet bandwidth options for your business with free consultation, solutions tailored to your particular needs and rapid price quotes that you’ll find very attractive for your IT budget.

IP WAN over MPLS Advantages

When we think of IP wide area networks, the first thing that comes to mind is the Internet. While the Internet does have almost universal connectivity and modest cost to access, there are some serious issues when it comes to business applications. Bandwidth, latency, jitter and packet loss have no guarantees and few expectations. Security is a joke. But aren’t other methods to interconnect business locations costly and hard to manage?

It is possible to set up a private IP network that lets you use your familiar IP addressing schemes and avoid encryption, firewalls, tunnels, and additional hardware. You’ll gain a performance advantage compared to using VPN techniques over the Internet and save yourself the administrative headaches of trying to manage a WAN with inherently indeterminate characteristics. Who offers something like this? It’s TelePacific, one of the nation’s largest competitive carriers.

TelePacific’s 1Net is an IP VPN running on a private MPLS network, not the Internet. Since MPLS or Multi-Protocol Label Switching can transport almost any protocol, it can be set up to mimic the Internet while keeping your data private. Only the locations that you set up can exchange traffic. No one outside of your user group can capture or view your data. You’ll have any to any connectivity within the group with security sufficient to address HIPPA or similar government regulations.

In fact, TelePacific set up just such a private IP Network for a medical imaging organization with 6 locations. They use it to transport patients’ private medical records among their location. Referring physicians can access patient imaging results within hours at their own computers. The system is also used for claims processing, patient scheduling and registration. Interestingly, this system also allows dedicated Internet access through a single firewall at corporate headquarters.

The TelePacific 1Net IP VPN has both cost and performance advantages over other secure networking solutions, including private line, ATM and Frame Relay. You can specify up to six different Classes of Service (CoS) to support sensitive real-time services such as VoIP telephone and teleconferencing. On Net, latency for all CoS is specified at 50 msec. That rises to just 100 msec for extended reach locations off the TelePacific network but still within the US. Network availability is 99.999% (5 nines) both on and off network locations.

The Classes of Service are CoS 1 for VoIP real time traffic, CoS2 for video conferencing and real time data traffic, CoS3 for high priority, delay sensitive business data like Ecommerce and Citrix, CoS4 for medium priority delay-sensisitive business data such as CRM and WebEx, CoS5 for general less delay sensitive business data like ERP, and CoS6 for best effort traffic with no prioritization. That’s typically Email and FTP.

Are you cringing at the cost and effort involved in linking your business locations by private lines or frustrated by the highly variable performance and difficulty in securing the Internet? Perhaps the best solution for your business needs is a private IP VPN based on MPLS networking. Check prices and features to compare with your other choices.

MPLS Service Providers Link Your Business Locations

It’s common for businesses to have multiple locations that need to be tied together with voice, data and sometimes video services. These can be branch offices, remote data centers, warehouses, franchises, factories and other business locations. What’s needed is a simple, cost effective way to link geographically diverse locations. MPLS service providers are ready to do just that.

Why MPLS? After all, there have been telecommunications services available for decades that can link one site to another. T1 point to point lines are readily available just about anywhere you need service. The public telephone network connects any phone to any other phone in the world. So what is it that MPLS networks have to offer that is new and different?

What MPLS is all about is privately owned and operated networks that serve large regions of the United States, some with national and even international footprints. These are what are also called “cloud networks.” The beauty of the cloud is that you don’t personally have to worry about the intricacies of wiring up and operating the many, many connections linking sites within the cloud. That’s all taken care of by the MPLS service providers. All you need is a link to the MPLS network from each of your locations. The network operator takes care of setting up the connections among your sites per your specification.

You might think that MPLS networks sound a bit like the Internet, and you’d be right. The similarity is in the way they make connections from anywhere to anywhere else. But that’s where the similarity ends. The Internet is a public resource with no quality of service mechanisms. If particular nodes get congested, packets wait or get lost. The Internet automatically sets up routing on the fly, so you never really know how your packets are getting from point A to point B. They just do somehow.

MPLS networks are engineered around predictable and dependable performance. Routing is done by a proprietary tagging protocol unique to MPLS networks. That makes them far more secure to outside intruders than the Internet. The tag switches have determinate paths that don’t change unless there is an equipment failure that needs to be worked around. Bandwidth, jitter, latency and packet loss are carefully controlled for each customer of the network.

What this all means is that MPLS networks work well for business users that set high standards for the quality, reliability and security of their telephone conversations and data transfers between locations. What MPLS providers can do is offer you a substantial cost savings over building your own private network to link multiple business locations. This is especially true if you have many locations scattered across a wide geographical area, including international offices.

How much of a cost difference is there between an MPLS network solution and what you are doing now for connectivity or have under consideration? Find out quickly and easily with a short inquiry to our knowledgeable Telarus consultants. They’ll get you competitive quotes from MPLS service providers that will clearly show how much you can save.
