100 Mbps Business Ethernet vs OC3 SONET Bandwidth

By: John Shepler

Many high tech companies and large corporations got into fiber optic bandwidth service years ago. The service they chose was the one available: OC3 SONET. Since then, many have upgraded to higher speeds, also in the SONET family of service, or simply stuck with the OC3 that has been performing reliably over the years.

The entrance of 100 Mbps and higher Ethernet MAN and WAN bandwidth is challenging the dominance of SONET fiber service. Long time users are taking a closer look at the competition. Companies upgrading or ordering bandwidth the for first time are doing their homework before choosing one technology over the other.

SONET (Synchronous Optical NETwork) in the SDH (Synchronous Digital Hierarchy) became the core of most metropolitan, wide area and international networks over the last decades. It was originally developed as a massive telephone trunking technology designed to bundle hundreds and thousands of simultaneous phone calls for long distance transport. With the rise of computer to computer communications and the Internet, SONET services were the logical choice to carry data packets as well as voice channels.

What does SONET have going for it? It is a very mature and well supported technology understood by all of the telephone companies and most network carriers. It is highly reliable and can survive certain fiber cuts and equipment failures. There are a number of service levels available between 155 Mbps and 100 Gbps. Costs have also come down over the years to the point where even smaller companies can consider the entry level OC3 SONET service.

Why throw over a winning service for a newer technology like Carrier Ethernet? It comes down to cost, service features and scalability.

In case you haven’t noticed, just about everything that can communicate uses Ethernet. This includes nearly every corporate LAN, all PCs, printers, scanners, routers, network switches and wireless access points. That’s expanding now to telephones, televisions and any other equipment that is joining the “Internet of Things.” Why not an all-Ethernet world?

The brand of Ethernet that leaves your property is called Carrier Ethernet. It has been standardized by and industry group, the Metro Ethernet Forum (MEF), so that it works over long distances, has the operations and maintenance features needed for carrier operations and is compatible from provider to provider.

Let’s compare two very common bandwidth services: 100 Mbps Ethernet vs OC3 SONET. Both are provided over fiber optic strands and delivered to your organization at a specified demarcation point. For Ethernet you use a simple Ethernet copper or fiber patch cord to connect your equipment to the carrier’s demarc. OC3 requires a special interface module that plugs into a router to convert between the Ethernet on your LAN and the SONET that runs on the carrier lines.

This is one reason why SONET is losing ground to Ethernet. If your network and everything on it is running Ethernet, why do a protocol conversion from Ethernet to SONET and back again at the far end just to send Ethernet packets from point to point over to the Internet? There are inefficiencies associated with that conversion process. Plus, you need a specific interface module for each SONET level. An OC3 module won’t work for OC12 or OC48.

SONET has specific service levels, although you can sometimes get fractional or rate limited services below the maximum line speed. Ethernet is scalable by design. The carrier provides an Ethernet port with a maximum speed, typically 100, 1,000 or 10,000 Mbps. Your actual service level can be any speed up to the capacity of the port. You pretty much pay for the bandwidth you are actually using rather than the capability of the circuit.

Scalability can also save you money. A 100 Mbps or Fast Ethernet connection on a 1,000 Mbps Gigabit Ethernet port can be scaled up or down easily. With SONET you start out at 155 Mbps for the entry level OC3. That sounds like 50% more bandwidth and it is. However, many companies really need 50 or 100 Mbps but had to buy 155 Mbps because it was that or nothing. If your 100 Mbps Ethernet connection bogs down, you can call the service provider and ask for an upgrade to 150 or 200 Mbps and have it in a matter of hours or days. If you tap out an OC3 connection, you have to wait days or weeks for an upgrade to the next generally available SONET level of OC12 at 622 Mbps.

Besides being able to order just the bandwidth you need now while knowing that you can easily upgrade when the need arises, Ethernet service tends to be less expensive than SONET on a per Mbps basis. But how about the quality of service? Both can deliver your packets with high reliability, low latency, and rock solid bandwidth. SONET tends to have fewer “flavors” available. It’s usually a protected ring arrangement with symmetrical dedicated bandwidth and five-nines (99.999%) reliability.

With business Ethernet, you need to be aware of what you are ordering. You can now get Carrier Ethernet with the same redundant path protection as SONET to ensure that if one circuit fails, the system will automatically switch to the other path in under 50 mSec. You can also get the same 99.999% reliability, low latency & jitter, and symmetrical dedicated bandwidth that you’ve come to expect with SONET services. However, if your applications aren’t so critical and you are more interested in saving money than in having the ultimate in performance, be aware that you can also order Ethernet services with asymmetrical bandwidth, shared bandwidth and unprotected circuits. These flavors of Ethernet work well for general Internet usage and casual PC backup to the cloud and are considerably cheaper.

FastE Fiber as MetroE for Business Ethernet Service

Business bandwidth demands are not only rising, but rising fast. What’s a good solution for fast data transfer? Fast Ethernet is an excellent option. It is readily available and affordable over fiber optic connections nationwide. Let’s take a closer look at how FastE works and how it fits into your bandwidth strategy.

Chances are that you’ve been using Fast Ethernet or FastE for years on your own network. Fast Ethernet is another name for 100 Mbps Ethernet. Standard Ethernet is 10 Mbps, Fast Ethernet is 100 Mbps and Gigabit Ethernet is 1,000 Mbps. Network Interface Cards (NICs) in every device with an Ethernet jack, also called a port, support one or more of these Ethernet speeds. For instance, a 10/100 port supports Ethernet communications at 10 Mbps and also 100 Mbps. A 10/100/1000 port includes 10 Mbps, 100 Mbps and 1000 Gbps.

Nearly every computer, switch, router, modem, firewall, printer, NAS (Network Attached Storage) Disk and other network device supports 10/100 Ethernet. The 10/100/1000 spec is becoming more and more prevalent. In both cases, these devices support Fast Ethernet at 100 Mbps.

So, what doesn’t support Fast Ethernet communication? Many MAN and WAN connections come nowhere close. Clearly computer technology has accelerated faster than communications technology. Actually, support for 100 Mbps communication over long distances has been available for a long time. It’s just that you needed special interfacing and the cost was beyond what most businesses were willing to pay.

High priced proprietary data communications are a legacy of the telephone industry. Nearly every company has ordered a DSL or T1 line to be able to communicate between business locations and connect to the public Internet. The cost of those lines has fallen dramatically in recent years. Even so, the limited bandwidth is starting to become an uncomfortable constraint on even smaller operations.

What’s changed the game recently is the introduction of Carrier Ethernet services. Carrier means that you lease these lines from a service provider, a carrier, rather than stringing the wires yourself. Any connection that goes beyond your property is handled by carriers. At one time the only carrier available was the local telephone company. Deregulation has allowed other service providers, called competitive carriers, to enter the marketplace and compete on technology and price.

Carrier Ethernet is one of those competitive services, although you’ll now find it offered by incumbent as well as competitive carriers. What’s allowed Carrier Ethernet to grow by leaps and bounds is standardization by an industry group called the MEF or Metro Ethernet Forum. Any provider that meets the MEF standards will be compatible with Carrier Ethernet equipment and interconnection with other provider networks.

Fast Ethernet is one of the Carrier Ethernet services you can order in both metropolitan and long haul connections. These are known as MAN or Metropolitan Area Networks and WAN or Wide Area Networks. The difference is really one of scale. The MAN serves a local geographical area that includes a city and surrounding suburbs. The WAN joins cities and may cross state and national borders. International WANs use undersea fiber to link far-flung destinations worldwide.

Metro networks based on Ethernet rather than the older SONET technology are sometimes referred to as MEN or Metro Ethernet Networks. You’ll hear them referred to as MetroE networks. These networks are almost always based on fiber optic rather than copper lines. Increasingly, so are the connections to the network. It’s fiber all the way for FastE and above.

What kind of connection can you make to a MetroE network. One of the most popular is the Fast Ethernet or FastE connection at 100 Mbps. Another popular service level is GigE at 1000 Mbps. What’s just emerging now as a business service level is 10 GigE at 10000 Mbps or 10 Gbps.

Going Ethernet all the way through your network, across the metro or wide area networks and to another LAN at the far end, has some real benefits. The interface is trivially easy. Your handoff from the carrier is a standard fiber or copper Ethernet jack. You’ll also be able to order both point to point connections called E-Line and meshed multi-location connections called E-LAN. Don’t think that you are stuck with only the standard Ethernet speeds either. You can generally get many increments between 10, 100, 1000 and 10000 Mbps.

The biggest advantage of all is cost savings. You’ll pay far less per Mbps for Ethernet than other services. The difference is sometimes half as much for Ethernet as SONET or other telecom services. This easily allows you to afford the bandwidth you really need for today’s communication-intensive applications such as cloud services.

Is your business bandwidth constrained? No need to be stuck at low copper technology speeds when fiber connections to high bandwidth metro and wide area networks are available and affordable. Check now for bandwidth services and prices available for your business location.

Will Elastic Bandwidth Help Your Company?

A big advantage to professional telecom services like T1 lines and SONET fiber optic connections has been the rock solid symmetrical bandwidth they provide. Order a T1 line and you can count on 1.5 Mbps in both directions all the time. Likewise, a SONET OC-3 service gives you 155 Mbps, also bidirectionally 100% of the time. What if that is no longer the type of bandwidth you need? What if you need something that can scale up and down at will? Welcome to the world of elastic bandwidth.

You might be thinking that this is similar to the kind of “best effort” services provided by DSL or Cable broadband. Those services do, indeed, provide variable bandwidth. However, the bandwidth that you get is determined by the traffic level on the network. If many users are demanding service at the same time, the total bandwidth gets divvied up and everybody gets less than the maximum capacity of the connection.

Elastic bandwidth is something different. Instead of being at the whim of network congestion, you actively control the capacity of your connection. You scale it up or down to meet your needs at the moment.

The service provider tw telecom is a pioneer in the field of elastic bandwidth with the recent introduction of their Dynamic Capacity service. Instead of a fixed amount of bandwidth that is determined when the line lease is signed, Dynamic Capacity users have the ability to scale up their bandwidth in a matter of seconds without service interruption. This is done by the customer themselves using a self-service portal. What’s more, users can schedule bandwidth increases for a particular amount of time to accommodate particular events such as overnight data backup. The programmed bandwidth changes then occur automatically without anyone having to manually intervene.

This goes far beyond previous solutions that include the ability to burst or use more bandwidth than you are allocated for short periods of time. It’s something of an extension of the rapidly scaling feature offered by many Business Ethernet providers. Carrier Ethernet is designed to be much easier to scale up and down than legacy line services. Providers will typically let you increase your bandwidth with a phone call to their office. It may take a few hours or a few days to realize the change, but this is far superior to having to wait weeks for a truck roll to change out equipment or make adjustments to the WAN network.

Dynamic Capacity is one of several phases of tw telecom’s Intelligent Network approach. The idea is to create a far more flexible network design that includes customer IT management in the loop. The first phase introduced detailed performance data reporting of Ethernet or IP VPN services. An future phase will add API’s (Application Programming Interfaces) so that applications themselves can request bandwidth changes as needed.

With the advent of cloud services, the concept of resource elasticity is gaining steam. Virtualization of servers and storage makes it easy for customers to provision more resources themselves in a matter of seconds or minutes. You simply pay for what you use and can change your mind anytime, depending on current business demands. Now, that same elasticity is being applied to WAN and metro Ethernet bandwidth services. This seems like the final piece in the puzzle to optimize the performance of cloud services.

Are you frustrated by fixed or limited networking resources? If so, then perhaps a bandwidth increase or an elastic solution like Dynamic Capacity would make a big difference in your business. Get options and pricing for copper and fiber bandwidth solutions now.

Business Ethernet Vs T1

Small and medium size businesses have been big users of T1 lines in the last few decades. Now there is a new service that is challenging the price and performance of the venerable T1 line. That service is Business Ethernet.

Business Ethernet, also known as Metro Ethernet, Ethernet over Copper and Ethernet over Fiber, offers scalable higher bandwidths, lower cost per Mbps, and increasing availability. It’s called “Business Ethernet” to emphasize that Ethernet isn’t just for LANs and carriers anymore. It’s being rapidly deployed into the SMB arena.

What’s so great about Ethernet? It’s now the universal standard for computer networking. Nearly every desktop PC, router, switch, and cabling infrastructure is designed to support Ethernet. Manufacturing economies of scale ensure that it will be tough, indeed, for another other technology to bee the price/performance of Ethernet.

The proliferation of Ethernet has also caused telecom carriers to rethink their public networks. T1 lines, DS3 bandwidth and OCx services are all based on circuit switched standards established to transport telephone calls. Ethernet is a packet switched technology that can be carried on circuit switched networks. With most networks now packet switched, it only makes sense to make the telecom networks packet switched also.

Packet switching end-to-end offers some interesting possibilities. If the LAN, MAN and WAN all support Ethernet, then you can establish level 2 switching to interconnect multiple business locations. Each location has its own LAN and they are tied together with MAN and WAN Ethernet services. You are extending your company network to encompass the connections between locations as well.

Business Ethernet is a scalable service. That means you can order a range of bandwidths for your connection, also called a port. As long as you stay within the capacity of the port, you can often get bandwidths in small increments including 1 Mbps. That way, you can order just the amount of bandwidth you need today, but can quickly upgrade with a phone call to your provider when business increases and you need more. It’s a great strategy to optimize costs and still get the performance you need right now.

How about the cost comparison with T1? It varies somewhat with location and the amount of competition for your business, but it’s not unusual to get 3 Mbps Ethernet for what you pay now to get a 1.5 Mbps T1 line. A popular service is 10 Mbps Ethernet. That costs about what you were paying for T1 a contract or two ago.

One service of particular note is Ethernet over Copper. This technology uses special terminal equipment installed by the service provider to bond multiple copper pair for your telecom connection. This gives bandwidths up to 50 Mbps over already installed copper wiring so you don’t have to pay for a new fiber installation. T1 lines can also be bonded, but the bandwidth tops out at 10 or 12 Mbps.

Which service is right for your business? They’re both professional grade and highly reliable digital line services. Why not get a set of competitive quotes for T1 vs Business Ethernet and see which will save you the most money?
