Pseudo-wire deploying method, failure processing method, associated equipment and dual-homing protection system

Abstract

The embodiment of the invention discloses a pseudo-wire deploying method, a failure processing method, associated equipment and a dual-homing protection system. The pseudo-wire deploying method comprises the steps as follows: primary network equipment receives a third parameter of a first escape pseudo-wire from standby network equipment on the standby network equipment, and a fourth parameter of a second escape pseudo-wire on the standby network equipment, wherein the third parameter is used for indicating that the first escape pseudo-wire protects a standby pseudo-wire or a standby access link; the fourth parameter is used for indicating that the second escape pseudo-wire protects the standby access link or the standby pseudo-wire; the primary network equipment determines whether the escape pseudo-wire deployment is correct or not according to a first parameter, a second parameter, the third parameter and the fourth parameter, wherein the first parameter is used for indicating that the first escape pseudo-wire protects a primary pseudo-wire or a primary access link, and the second parameter is used for indicating that the second escape pseudo-wire protects the primary access link or the primary pseudo-wire. According to the embodiment of the invention, the method of the invention could timely find the error deployment of the escape pseudo-wires and avoid the invalidation of a protective network, thereby improving reliability of the network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a pseudowire deployment method, a fault handling method, related equipment, and a dual-homing protection system. Background technique [0002] The Pseudowire (PseudoWire, PW) redundant application technology can solve the problem of fault protection of the PW network and improve the reliability of the network. In practical applications, in order to further improve the reliability of the network, an escape PW is added between the network devices on the dual-homing side. Used for quick switching. [0003] According to different business models, there are two methods for the application of escape PW. One is the single escape PW mode, that is, there is only one escape PW between the network devices on the dual-homing side; the other is the double escape PW mode, that is, dual-homing There are two escape PWs between side network devices. [0004] In the deployment scenario o...

Problems solved by technology

[0004] In the deployment scenario of dual escape PWs, it is necessary to ensure that the same escape PW protects different line types on the active network device and the backup network device during configuration. However, two escape PWs need to be configured on the two device sides , often after configuration, the same escape PW protects the same type of line on the active network device and the backup network device, that is, the escape pseudo-wire deployment error occurs, and the escape pseudo-wire deployment error will cause data transmission to form a loop , causing the protection network to fail
