Gigabit Metro Fiber Ethernet Means Business

By: John Shepler

More and more companies are running out of bandwidth as demanding applications eat up every Mbps of LAN, MAN and WAN bandwidth they can access. Are you doomed to fight a losing battle or is there a good technical solution available?

More Bandwidth to the Rescue
Don’t expect to roll back the clock and be able to do business today and tomorrow with the connections you ordered yesterday. X.25 is long gone. T1 lines have about had their last hurrah. Ethernet over Copper is a temporary solution, at best, to buy you time for what you really need to do. That is, connect to the world via fiber optic bandwidth

But What About Cable?
Cable broadband, also called D3 or DOCSIS 3 for the technical standard, is actually a good solution for some applications. Just don’t kid yourself. That cable connection doesn’t really go very far until it hooks up with the cable company’s metro fiber plant. The junction box may be a few blocks away or it might be handing on the utility pole you can see from your office.

The same is true for T3 or DS3 bandwidth, the longstanding upgrade path from T1 lines. The connection to your equipment may be a pair of coaxial cables, but they only go out to the street. At they point they join up with a SONET fiber optic system owned and maintained by the local telephone company.

What’s Special About MetroE Fiber?
Ethernet is the newer and future-proof technology for carrying digital traffic on fiber optic systems. It is based on the same Ethernet standards used for your local area networks. Certain standards have been added to fit with carrier operations, but otherwise it is switched Ethernet.

That means the interface between your LAN and the carrier’s MAN or WAN is trivially simple. Just plug in and go, like you would with any router or switch. No special interface cards are needed. Chances are that the carrier who is providing your service will install a managed router at your business to define the network edge.

Metro vs Internet
Metro Ethernet, strictly speaking, is a network that serves a particular city or city plus suburbs. The most common use has been to interconnect business locations that are geographically close. These may include headquarters, data centers, warehouses and branch offices. Some companies choose to include suppliers and important customers on their MetroE network for high connection speed and security.

Metro Ethernet is a point to point or multipoint service that directly connects particular locations. You can elect to order ELAN service that actually extends your local network to the other locations. It’s just like you ran your own cables across town, but without the prohibitive expense of doing so.

The Internet is another animal. It’s actually a massive worldwide network made up of national, regional and city-wide networks that all agree to a common standard. Metro Ethernet is not the Internet, but it can connect to it. MetroE networks can also connect to each other over longer distances, especially when ordered through the same carrier.

Why Order Metro Ethernet?
You can think of Carrier Ethernet or Metro Ethernet as the new gold standard in telecommunications. It gives you high bandwidth connections that are easily scalable and low in latency, jitter and packet loss. You have exclusive use of the bandwidth you’ve ordered. It’s also generally covered by a service level agreement to ensure that you get the highest level of availability.

That’s important because the tradeoff between Metro Ethernet and Cable Broadband is not so much in the connection method. Cable provides you with a shared bandwidth service that varies in speed depending on how heavy the usage is. Service is generally on a “best effort” basis rather than any particular guarantees of performance or availability. Thus, the lower price for a given bandwidth level. Some businesses, especially smaller ones, find this tradeoff well worth making. Others with large user bases and critical applications may find that only dedicated service is acceptable.

By the way, many Cable companies also offer Metro Ethernet service on their fiber backbones. It’s a different class of service with a different pricing structure than the coax connected business broadband offering.

Is Metro Ethernet For You?
If you are running out of bandwidth or already at the limit, or simply want a service that can easily be upgraded in the future, you should take a serious look at Metro Ethernet for your business. You may be able to get a break on construction costs or even have them waived if you sign a long term contract, have high enough bandwidth requirements or can join forces with other business customers in your building. There are likely multiple carriers serving your area. Find out what each can offer with a set of competitive quotes for Metro Ethernet service now.

Ethernet over Copper Connects Nationwide

Ethernet over Copper (EoC) has quickly made a name for itself as a last mile access connection for dedicated Internet, MPLS networking, and linking two or more company LANs. The flexibility, ease of interface, and cost savings make this a service in demand. What’s held it back to date is lack of availability. Well, that’s about to change.

MegaPath, one of the country’s major competitive carriers, is moving in with Telx, a major network interconnection provider. What does that mean? It means that your Ethernet over Copper connection can go a lot farther than it used to.

MegaPath has been on a major construction effort to roll out EoC equipment to over 680 central offices within the next year. The central office is key because this is where the subscriber copper loops terminate. MegaPath used specialized G.HSDL technology with up to 8 bonded copper pair to deliver line speeds to 100 and even 400 Mbps in selected area. Their standard symmetrical speeds are 2, 3, 5, 8, 10, 12, 15, and 20 Mbps. Both layer 2 and layer 3 services are offered along with QoS/CoS to support business data and real-time voice and video simultaneously.

For its part, Telx operates 15 data centers with direct access to over 950 customers who have chosen to colocate within the Telx facilities. These include major telecom carriers, Internet service providers, content producers and delivery networks and cloud service providers. Telx is a pioneer in Ethernet Exchange, a way for carriers to exchange Ethernet traffic without having to first convert to another protocol like SONET. The E-NNI or Ethernet Network to Network Interface benefits each carrier who participates because now they can directly access customers on other carriers and vice-versa.

Ethernet over Copper along with Ethernet over Fiber form the basis of Carrier Ethernet. This is the familiar Ethernet protocol that runs on your LAN adapted for use on telecommunication networks. The Metro Ethernet Forum (MEF) has standardized a number of Carrier Ethernet standards so that they are compatible across network boundaries. These include EPL, EVPL, and ELAN.

EPL stands for Ethernet Private Line. This is equivalent to the point to point private line services familiar with T-Carrier and SONET services. EVPL is Ethernet Virtual Private Line. This is very similar to EPL. The virtual designation means that you can have a number of EPL services running to a single physical Ethernet port. This is particularly useful for companies that want to run private lines from a single headquarters location out to multiple branch locations. Together, EPL and EVPL form what is known as E-Line or Ethernet Line service.

ELAN stands for Ethernet LAN Service. You may also see this written as E-LAN. What differentiates E-LAN from E-Line is that E-LAN is a many to many or mesh network service. You can use it to tie together multiple business locations so that any location can communicate with any other.

Have you been interested in Ethernet over Copper services but concerned that they may not be available to support your particular location or your many locations nationwide? This is a rapidly changing market, with more service being rolled out almost daily. If you haven’t checked lately, you may be pleasantly surprised at how much connectivity is available and how much bandwidth your can get for your telecom budget. Check pricing right now, if you like. Ethernet over Copper prices from 1 to 100 Mbps are available instantly online. Other services for business locations will be promptly quoted by a Telarus bandwidth expert, upon request.
