Abstract
The present invention provides a method and system for increasing forwarding efficiency of a virtual private LAN services network. The method includes: a root node provider edge (PE) in the VPLS network transmitting at least one of broadcast message, multicast message and unknown unicast message to leaf nodes PE in the same VPLS through a point-to-multipoint pseudo wire (P2MP PW). The present invention transmits messages through the P2MP PW between a PE and other PEs, thus decreasing the number of redundant messages on a physical link, increasing the forwarding efficiency of network, and reducing the network operating costs.
