  • Reliability processing methods and systems in the networking of metro ethernet network providing multi-service
    Patent number: 8320389
    Abstract: A reliability processing method and system in networking of Metro Ethernet Network providing multi-service are provided. The method includes: establishing a Virtual Router Redundancy Protocol (VRRP) group with at least two service control gateways, establishing network connections between an access device (UPE) and the service control gateways in the Virtual Router Redundancy Protocol group by a Virtual Private LAN Service (VPLS); establishing Layer 2 service and Layer 3 service connections between an active service control gateway and the Access device after active and standby service control gateways in the Virtual Router Redundancy Protocol group are determined according to a processing result of a Virtual Router Redundancy Protocol message, and performing Layer 2 service and Layer 3 service processing.
