EVPL Ethernet Virtual Private Line Service

You are probably familiar with private line services for business. A private line is one where you have exclusive use. An analog telephone line is a private line. So is a T1 voice or data line. Now there is something new is the mix. It’s the VPL or Virtual Private Line.

Decades ago, several houses in a neighborhood would be connected to the same physical line. If you picked up your phone to make a call, you might hear one of your neighbors already engaged in conversation. In the pre-Twitter days, listening-in on other phone conversations was often a form of amusement.

That lack of privacy is long gone for telephones. But shared digital services exist today, especially with public access Internet. No, you can’t casually eavesdrop on your neighbors email or Web activities, but if some of the users start heavily downloading large files, your Internet service will slow down. There are also tools available that allow anyone to monitor everything going over a particular WiFi hotspot. The whole Internet is one big party line in the sense that you can’t be sure who’s monitoring the traffic and what they might be doing with information they skim.

It’s the security risk and the lack of consistent bandwidth that have driven businesses to private line service. T1 lines are private lines. They offer the advantages of rock solid 1.5 Mbps bandwidth and exclusive use of the line. The disadvantage is that you pay for that line even when traffic is light or non-existant.

Ethernet also offers a private line service called EPL. It works like T1 in that it is a physical line connection between you and your service provider. The difference is that the protocol is Ethernet and you can often get scalable bandwidth, typically 10 Mbps.

If you have a private line service, why would you want a virtual private line service? For one reason, you may want private lines running from your headquarters out to a number of branch offices. With dedicate private lines, you need separate physical circuits for each of these lines. You pay for the exclusive full time use of each circuit and there may or may not be enough pairs of wire into your headquarters office to give you the number of private lines you desire.

Ethernet Virtual Private Line service, EVPL, uses a single physical copper or fiber circuit to connect you to the service provider. Within that circuit are multiple EVCs or Ethernet Virtual Connection. This is not a party line arrangement. Each EVC carries its own traffic to and from another location without any cross-talk or interference from other EVCs.

The power of EVPL is not only that you only need one network interface at each of your facilities, including headquarters, but that those virtual connections can be extended to other cities or states over the provider’s MPLS core network. The MPLS is a cloud network that carries traffic for many users, but the integrity of each user’s virtual circuit is maintained from point to point regardless of distance.

EVPL is also a switched layer 2 service, which means that you can use it to extend your LAN network across town or across the country. It’s the simplest way to bridge multiple LANs when they are not located in the same facility.
