RELIABILITY PROCESSING METHODS AND SYSTEMS IN THE NETWORKING OF METRO ETHERNET NETWORK PROVIDING MULTI-SERVICE

摘要

A reliability processing method in networking of Metro Ethernet Network providing multi-service 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); performing Layer 2 service and Layer 3 service processing, 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. Therefore, the reliability of the Layer 2 and Layer 3 services of the MAN may be sufficiently guaranteed, and the overhead of the system may be reduced significantly.
