Embodiment Construction

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Such as figure 2 As shown, it is a flow chart of a preferred embodiment of the protection method of the same source and same destination PW in the present invention; it includes the following steps:

[0041] Step S001: Binding step: generate a PW LIST instance, incorporate the working PWs of the same source and same destination on the PE into the above PW LIST instance and bind them;

[0042] In this way, PWs of the same source and same destination are included in a PW LIST group.

[0043] Step S002: Configuration step: configure one working PW ...

Abstract

The invention relates to a PE (provider edge router) and a protection method of homologous homoclinic PWs (pseudo wires), the PE comprises a PW service management module, a PW OAM (operation administration and maintenance) detection module and a PW protection group module, and the method comprises the following steps: pre-binding the homologous homoclinic working PWs on the PE together and configuring OAM detection for one of the working PWs; performing periodical link detection on the working PW configured with the OAM detection after the PE works; reproducing the detection result to other working PWs which are bound to the working PW after the failure of a physical link of the physical link of the working PW or the recovery of the failure is detected; and performing switching treatment or switching-back treatment on the corresponding working PW according to the detection result. By adopting the PE and the method, the complexity in network deployment is reduced, the reliability of a network is improved; and the method is simple to the implement.

Description

technical field [0001] The present invention relates to the technical field of data network communication, in particular to a protection method for a PE (Provider Edge router, backbone network edge router) and a PW (Pseudo Wire, pseudowire) with the same source and destination. Background technique [0002] With the development of data network technology, network operators tend to adopt efficient and low-cost packet transmission network to realize multi-service bearer, reduce the complexity of network deployment, and increase the flexibility of network services. As the networking complexity of carrier-class Ethernet is getting higher and higher, operators are eager to reduce the complexity of network deployment, but at the same time, they cannot reduce network reliability and protection switching performance. In order to ensure the reliability of the network, OAM (Operation Administration and Maintenance, operation management and maintenance) fault detection technology and a...
