Abstract:
1. A reliability processing method implemented in a Metro Ethernet Network providing for multiple services, the method comprising: establishing a Virtual Router Redundancy Protocol (VRRP) group with at least two service control gateways; establishing, by a Virtual Private LAN service (VPLS), network connections between an access device and the service control gateways; determining an active service control gateway and a standby service control gateway in the Virtual Router Redundancy Protocol group according to a processing result of a Virtual Router Redundancy Protocol message; establishing a Layer performing Layer establishing, by the access device, a first VPLS Pseudo-Wire (PW) and a second VPLS Pseudo-Wire (PW) for each accessed service, wherein the first VPLS PW is connected to the active service control gateway and the second VPLS PW is connected to the standby service control gateway; setting, by the active service control gateway, the first VPLS PW to an active state; and setting, by the standby service control gateway, the second VPLS PW to a standby state, wherein the second VPLS PW sends and receives the VRRP message; establishing an additional Layer for the Layer sending, by the altered active service control gateway, a media access control (MAC) address withdraw message to the access device by the second Virtual Private LAN Service control protocol; broadcasting, by the access device, a message to the service control gateways in the Virtual Router Redundancy Protocol group; responding, by the new active service control gateway, a message to the access device; and performing, by the access device, Layer
