Ethernet tree (E-Tree)

The Metro Ethernet Forum (MEF) has defined three Ethernet services for Carrier Ethernet: E-LAN, E-Line

, and E-Tree.E-Tree forms a routed point-to-multipoint (P2MP) link. From the transmission point to the receiving facilities, the connection is multicast; in the reverse direction, it is a point-to-point (P2P) connection. These connections are called Ethernet Virtual Connections

(EVC), and E-Tree is ideal for multiplexed connections to the Application Service Provider (ASP) or Internet Service Provider (ISP). However, the service functionality is limited because the receiving end nodes cannot communicate with each other.
