Gigabit Ethernet Port Scales WAN Bandwidth

When you are ready to make the move from copper to fiber bandwidth levels or upgrading an OC-3 SONET service, you are faced with a choice. What level of bandwidth do you install?

Why not give yourself flexibility for the future and the opportunity to pay only for what you need right now? This is what a Ethernet port strategy can do for you.

Scalability is a new idea in business telecom services. When you install a T1 line, it requires a very specific T1 interface that include a CSU/DSU circuit unique to the T1 line specifications. Upgrade to a T3 line (DS3 bandwidth) and you’ll find that you can’t just plug that T3 into your T1 router. The interface is completely different. Even the connecting cable is different. With DS3 you are looking at a pair of coaxial BNC connectors that don’t support any other service. Now, make yet another move on up to OC-3 service. Your router interfaces for T1 and T3 are no good. You need a fiber input to your router.

It doesn’t get any better when you start moving up the fiber optic hierarchy. You can’t just plug OC-12 or OC-48 into an OC-3 port and have everything spring to life. They are different services requiring modifications. You’ll likely need a new interface card and programming changes to your router. If you have a managed router, that probably means a truck roll to your premises to swap out the CPE (Customer Premises Equipment).

In the back of your mind, you must suspect it doesn’t have to be this way. Those new PCs have NICs (Network Interface Cards) labeled 10/100/1000 Mbps. That means that you can plug them into any LAN running at up to 1 Gbps and they’ll work just find. Even the connector takes the same RJ-45 patch cord. Wouldn’t that approach be far superior for WAN connections too?

This is the beauty of Carrier Ethernet, which includes Metro Ethernet, MPLS network access and long haul point to point connections. Ethernet beyond the LAN has been designed to be as flexible as Ethernet on the LAN.

One of Ethernet’s best features as a bandwidth service is ease of scaling. If you are running 50 Mbps service and find your needs have increased so that you now need 100 Mbps, you can just call up your service provider and request an upgrade. In a matter of hours or a day or two at the most, your WAN network speed will double. In that time, no one has knocked on the door with a new router under their arm. In fact, you haven’t seen anyone from the service provider. It was all done over the phone.

There is a trick to making this work. The magic is all in the installed Ethernet port. When you order Ethernet service, make sure that you have a port installed that will support the highest bandwidth you reasonably expect to be ordering down the road. Most ports are the standard Ethernet speeds of 10 Mbps, 100 Mbps and 1,000 Mbps. It’s also possible to get a 10,000 Mbps or 10 GigE port with a suitably fast managed router if your needs are that high.

With Ethernet over Copper, you are probably looking at a 100 Mbps Ethernet port at most. Be sure you know just what your maximum speed will be, because EoC is distance limited and requires more copper pairs as speed increases. Ask what bandwidth your installation will support compared to what you are ordering initially.

With Ethernet over Fiber, it likely makes sense to install a Gigabit Ethernet port. The fiber itself has more capacity that you are ever likely to employ. The speed of the port will be the limiting factor, along with the capability of the carrier’s equipment that feeds that port. Once again, it is smart to plan for the future but buy for today. Get the bandwidth you need now, but be sure that the system is engineered to allow for fast and easy upgrades as you need them. That will be especially handy if you get hit with a sudden increase in traffic or a need to support massive amounts of video or enormous file transfers that you didn’t anticipate.

Are you ready for a bandwidth upgrade, but unsure of what commitment to make? Give yourself some breathing room with a Gigabit Ethernet port and the ability to scale up your bandwidth as needed. Get prices and availability of Ethernet ports and line speeds now.

Combine T1 Lines For Higher Speed

T1 lines have been popular with small and medium businesses for decades. They are highly reliable, private, dedicated bandwidth, and easy to come by. With fierce competition bringing down prices in recent years, what’s not to like? If only you could get T1 lines to run faster....

There’s a way to do that and still keep all the advantages of T1 line technology. The technique is called bonding. It’s an industry standard method of combining the bandwidth of multiple T1 lines so that they behave as a single much larger connection.

You can’t really hot-rod a single T1 line. The system was designed to be synchronized so that the line can be segmented into 24 separate telephone lines or multiplexed into higher bandwidth services. A T1 line runs at 1.5 Mbps and that’s that. What bonding does is let you bring in another T1 line and hook the two together for 3 Mbps.

Why upgrade in the first place? Bandwidth demands are increasing. You know that every few years you need to upgrade the processing power and RAM in your PCs to keep running efficiently with upgraded browsers and other applications. Expect the same to be true of your WAN connections. Whether it’s file transfers from point to point between business locations, Internet access or a connection to cloud services, you’ll need higher bandwidth to stay competitive.

T1 lines can be combined in larger groups to give you even more bandwidth. Bonding 3 T1s provides 4.5 Mbps, 4 T1 lines offer 6 Mbps, 5 bonded lines equal 7.5 Mbps, 6 T1s provide 9 Mbps, 7 T1 lines offer 10.5 Mbps and 8 bonded T1 lines get you to 12 Mbps. Eight line bonding is about as high as most carriers go. The cost of bonded T1 is equal to the price of a single T1 times the number of lines used. When you get past 8 T1s it is generally cheaper to move up to DS3 or even fiber optic connections.

How do you connect all these T1 lines coming into your facility? Your service provider will take care of that. They supply a managed router with multiple WAN Interface Cards (WIC) that handled the interface to each T1 line. The router then does the bonding in tandem with carrier equipment on the other end and delivers a single bandwidth port (RJ45) running at the higher bonded speed.

This is important. For bonding to work, you need to get all of your T1 lines from a single provider. If you try to mix and match vendors, they have no way of coordinating line operation and you just wind up with Individual T1 lines. You can do load balancing with your own routers or buy a bandwidth aggregation appliance to combine unrelated lines, but this is not true bonded T1.

Does any other service compete directly with bonded T1? Yes, Ethernet over Copper does something very similar. It bonds multiple twisted copper pair (up to 8 pair) to deliver a single bandwidth service from 2 Mbps to over 100 Mbps. The trick in delivering the higher bandwidths is a more sophisticated modulation scheme that is distance sensitive. The nearer you are to the central office, the higher the speed available. If available, you can probably get higher bandwidths and better prices than bonded T1 services. However, availability is generally limited to metropolitan areas at this time.

Moving From OC-3 Bandwidth To Ethernet

Many medium size and larger businesses have been using OC-3 bandwidth over fiber optic connections for dedicated Internet access, video transport, remote data backup, large file transfers between sites and other high bandwidth applications. Now, there’s a newer lower cost option that can get you as much bandwidth or more for less money.

That solution is Carrier Ethernet. You may still think that Carrier Ethernet is a specialty service found in only a few areas by even fewer service providers. Not any more. Carrier Ethernet is mainstream. There is a mad dash underway to convert TDM based networks to IP packet networks. It may not be much longer that you’ll even be able to get OC-3 bandwidth services.

It’s all about the switch from telephone technology based on individual circuits to computer network technology based on packets. What’s happened in recent years is that the vast majority of traffic around the world has changed from voice to data to video. Voice is now thought of as one more service on a converged network that can transport voice, data or video with equal ease.

OC-3 is a TDM or Time Division Multiplexing technology. It has its roots in telephony, where everything revolves around small discrete channels that each carry one individual digitized telephone call. All of those channels are carefully synchronized by giving them each their own time slot in the bitstream.

So what’s wrong with that? Nothing other than the fact that using this methodology to transport packets that aren’t the same size as channels and don’t require the TDM synchronization unduly complicates the network interface and introduces inefficiencies. An OC-3 line runs at 155.52 Mbps with a payload of 148.608 Mbps.

Ethernet is the same protocol that runs on your corporate network. What Carrier Ethernet does is enable that same protocol to run for long distances on Metropolitan and Wide Area Networks.

Is there a direct Ethernet equivalent to OC-3? Not exactly. Ethernet does have standard LAN speeds of 10 Mbps, 100 Mbps, 1,000 Mbps and 10,000 Mbps. Carrier Ethernet is far more scalable, though. You can order just about any bandwidth you require. A 150 Mbps Ethernet service is pretty much equivalent to the OC-3 speed. You could, however, select 100 Mbps, 200 Mbps or some other bandwidth that more closely matches your true requirements.

Here’s something else that makes your life easier. Install a Gigabit Ethernet port and you can easily upgrade to any bandwidth up to 1 Gbps at any time. Start with 150 Mbps to match that OC-3 today and later move up to 300 Mbps, 500 Mbps, 750 Mbps or 1,000 Mbps when the need dictates. In the mean time, you’ll be paying for only what you need on that fiber optic link.

Moving from OC-3 to the next available standard of OC-12 means you’ll have to jump from 155 Mbps to 600 Mbps and wait for a technician to change out your router card or managed router. Moving from 150 Mbps Ethernet to 200 Mbps Ethernet or higher can be done with a phone call in hours or days, not potentially weeks or longer.

Best of all, Carrier Ethernet is almost always priced less per Mbps than OC-3 and similar telco services. The reasons are increased competition and a technology that is on the rise, not the decline. How much can you save by making the move from OC-3 bandwidth to Ethernet? Check fiber optic bandwidth prices and availability to find out how many competitive options are available for your business location.
