    摘要: The present invention presents a method for setting up a QoS (Quality-of-Service) supported bi-directional tunnel and distributing L2VPN (Layer-2 Virtual Private Network) membership information for an L2VPN using an extended LDP (Label Distribution Protocol). In a network providing MPLS based L2VPN service, which includes a plurality of VPN provider edges (PEs), a plurality of VPN customer edges (CEs) connected to the PEs and a VPN DNS (Domain Name Service) server for managing PE information associated with a plurality of VPNs, a PE registers information associated with the VPN DNS server to provide the L2VPN service, and uses the extended LDP for QoS supported bi-directional tunnel setup and the extended LDP for QoS supported L2VPN membership information distribution. A VPN CE needs only a simple Layer-2 connection providing function for the L2VPN service.
