Abstract

The invention discloses a system and method for achieving VPWS redundancy protection rapid convergence and relates to the technical field of network communication. The system comprises an access-side PE device A, a convergence-side primary PE device B and a convergence-side standby PE device C. The access-side PE device A comprises a first BFD / MPLS-TP OAM module, a first VPWS control module and an ARP / NDP caching transmitting module. The convergence-side primary PE device B comprises a second BFD / MPLS-TP OAM module, a second VPMS control module and a first ARP / NDP module. The convergence-side standby PE device C comprises a third BFD / MPLS-TP OAM module, a third VPWS control module and a second ARP / NDP module. By the adoption of the system and method for achieving VPWS redundancy protection rapid convergence, rapid switching of downlink services can be achieved, the protection requirement of interruption of a telecommunication network at the level of 50ms can be met, the stability and the safety of the network are improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a system and method for realizing fast convergence of VPWS (Virtual Pseudo Wire Service, virtual private line service) redundancy protection. Background technique [0002] With the advent of the mobile Internet era, the telecom business has gradually changed from the original voice service to the data service. Major operators have increased their investment in wireless networks and continuously increased the construction of wireless base stations. At the same time, they need to build larger mobile data backhaul The network supports the transmission and carrying of big data. In the access layer of the wireless backhaul network, VPWS is generally used to implement service bearer. VPWS is one of the application technologies of L2VPN (Layer2Virtual Private Network, Layer 2 Virtual Private Network). L2VPN provides users with a flexible VPN (Virtual Private Netw...
