Problems solved by technology

At this time, due to the interruption of the BGP signaling session, the pseudo-wire is interrupted, which causes the interruption of the customer service carried by the pseudo-wire, and greatly reduces the availability of VPLS.

Embodiment Construction

[0043] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0044] Considering the establishment and removal mechanisms of pseudowires provided by IETF's RFC4447 and RFC4761, it is easy for customer services carried by pseudowires to be affected by signaling session turbulence, reducing the availability of pseudowires. For this reason, the present invention provides a mechanism for improving the usability of the pseudowire, aiming at making the pseudowire continue to maintain its service forwarding state when the signaling session is interrupted, without dismantling the pseudowire service corresponding to the signaling session, thereby ensuring the The business continues to be forwarded.

[0045] The present invention is based on the following core ideas: the signaling session is interrupted, or the protocol processors of the local PE and the remote PE fail, and the forwardin...

Abstract

The invention discloses a pseudo wire service processing method, which comprises the following steps of: negotiating about the consistency of pseudo wire freeze configuration between a local provider edge (PE) and a remote PE in a static configuration or signaling notification way; if a signaling session between the local PE and the remote PE is interrupted or protocol processors of the local PE and the remote PE fail when the local PE and the remote PE are both configured with the freeze attribute of a pseudo wire, continuously keeping the forwarding state of the pseudo wire. The invention also discloses a pseudo wire service processing device. By the method and the device provided by the invention, the service forwarding state of the pseudo wire is continuously kept, and a pseudo wire service corresponding to the signaling session may not be stopped if the signaling session is interrupted or the protocol processors of the local PE and the remote PE fail, thereby ensuring the continuous forwarding of a customer service.

Description

technical field [0001] The invention relates to pseudowire technology in network communication, in particular to a method and system for processing pseudowire services. Background technique [0002] Pseudowire (PW, Pseudowire) technology is a solution proposed for future converged communication networks, and it is a technology for simulating traditional layer 1 and layer 2 network services on a packet switching network. Pseudowire technology is applicable to almost all networks, including transmission network and access network, enabling Multi-Protocol Label Switching (MPLS, Multi-Protocol Label Switch) to break through the core network and realize the true convergence of access network and metropolitan area network . [0003] Pseudowire is a point-to-point connection between edge routers (PE, Provider Edge). The establishment mechanism of pseudowire is defined in RFC4447 of Internet Engineering Task Force (IETF, Internet Engineering Task Force), and the target label distri...
