Ethernet services deliver network connectivity over short- and long-haul circuits, and termination on fiber and copper local infrastructures. The Metro Ethernet Forum specifies three types of connections: E-Line, which is based on a point-to-point connection (more suited to WAN); E-LAN, which is based on a point-to-multipoint connection; and E-Tree, which is also based on point-to-multipoint connections with reduced provisioning schemes.
