  • Metropolitan Ethernet
    • Sometimes referred to as Metro-E or Metro-optical
    • It is an emerging technology that allows service providers to connect campus networks together with layer 2 connectivity.
  • This technology allows for the network over a large area to act like a LAN.
  • The provider achieves this (enabling a network over a large area to act as a LAN) by building Ethernet virtual connections (EVCs) between the campus networks.
  • The customer can purchase point-to-point EVCs between two locations, or multipoint-to-multipoint EVCs between several location, to create a full meshed network.
  • Metro-E can also provide this connectivity over many different connectivity technologies, such as leased lines, ATM, SONET, and so on.
  • Metro-E is an extremely flexible connectivity technology that is cost effective and easy to configure, since it acts like a giant switch between network campuses.
