Abstract

The invention relates to a data communication technology, solves the problem that an existing VPN FRR technology cannot be implemented under the condition that a route reflector exists between a dual-homing / multi-homing PE and a far-end PE and provides service provider boundary routers, system and method for achieving fast VPN rerouting. According to the technical scheme, two novel service provider boundary routers are provided, the first service provider boundary router comprises a router identification presetting module, a sending module, a dynamic identification generating module and a router identification replacing module, and the second service provider boundary router comprises a receiving module and an analysis recovery module. The service provider boundary routers, system and method for achieving the fast VPN rerouting has the advantages that the far-end service provider boundary router can still support the fast VPN rerouting under the condition that the route reflector exists between the dual-homing / multi-homing service provider boundary router and the far-end service provider boundary router and is suitable for dual-homing / multi-homing networking.

Description

technical field

[0001] The invention relates to data communication technology, in particular to VPN fast rerouting technology. Background technique

[0002] L3VPN adopts MPLS (Multiprotocol Label Switching) technology to build an IP private network on the backbone network to realize cross-regional, high-speed and reliable forwarding of private data packets. Using MPLS VPN (Virtual Private Network virtual private network) technology can convert existing An IP network is decomposed into logically isolated networks. The application of this logically isolated network can be varied: it can be used to solve the interconnection of enterprises, the interconnection of the same / different departments of the government, and it can also be used to provide new services, such as opening a dedicated VPN for IP telephony services.

[0003] As users have higher and higher requirements for network reliability, the single point of failure of network service provider equipment has become a bott...
