Abstract
A method and system for switching the serving services of virtual private LAN is provided. When a fault occurs on a normal service transmission path, a PE device on the secondary path transmits a message including an information of the failure device on the normal service transmission path to the other PE devices on the path to indicate the path switching; the other PE devices replace the faulty PE device corresponding to the transmission path item in VPLS transmission table as the PE device on the secondary path according to the received message for indicating the path switching. Using the present invention, when an access device detects a fault, the VPLS service can switch to the secondary path immediately without affecting other services; because the VPLS messages do not need to be broadcasted during path switching, the network bandwidth will not be wasted.
