Title:
RELIABILITY PROCESSING METHOD AND SYSTEM OF METRO ETHERNET NETWORK WHICH PROVIDES MULTI-SERVICE GROUP NETWORK
Document Type and Number:
WIPO Patent Application WO/2008/095365
Kind Code:
A1
Abstract:
Reliability processing method and system of Metro Ethernet network which provides multi-service group network, includes at least two service routers comprising a virtual router redundancy protocol group. The network connection relation is created separately between the user facing provider edge router and the service router in the virtual router redundancy protocol group using the virtual private LAN service; the main and the backup service routers are determined according to the processing result of the virtual router redundancy protocol message, and the connection is created between the service router and the two-layer and three-layer of the user facing provider edge router, then the two-layer service and three-layer service of the main service router are processed. The invention may switch all of the two-layer and three-layer services to the backup service router quickly when the network is out of work, the switch time interval is less than one second; it can ensure reliability of the two-layer and three-layer services in Metro Ethernet network; and it can decrease the cost of the system.
