Problems solved by technology

[0005] There are communication devices that do not support VCCV-BFD or T-LDP in the live network, and these devices cannot use VCCV-BFD signaling or T-LDP signaling to transmit faults on the network side
Therefore, in the prior art, there is no implementation scheme that supports network-side fault transmission for the entire network.

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] The VCCV-PING message is the basic operation and maintenance requirement of PWE3 (Pseudo Wire Emulation Edge to Edge, end-to-end pseudo wire emulation), and all communication devices in the PWE3 network support the VCCV-PING message. In the embodiment of the present invention, by extending the VCCV-PING message, network-side fault detection is realized, and then operation and maintenance mapping is realized.

Abstract

A method for realizing failure detection comprises the steps of receiving a virtual circuit connectivity verification VCCV-PING message which carries transmitting terminal state information; analyzing the VCCV-PING message, judging whether the transmitting terminal has a failure according to the transmitting terminal state information, and locally setting failure identification when the transmitting terminal has a failure. An embodiment of the invention further provides a device and a system for realizing the failure detection. As the VCCV-PING message is the basic OAM requirement of PWE3, using the extended VCCV-PING message to realize the failure detection is capable of supporting the whole network to realize network failure detection, realizing complete operation mapping, and reducing system realization complexity, development cost and maintenance cost.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an implementation scheme of fault detection. Background technique [0002] In order to improve the operability of the network and ensure the reliability of the network, when a fault occurs on the network side, it is necessary to use the network technology on the AC (Access Circuit) side to send the network side Fault notification enables CEs on both sides of OAM Mapping (OAM, Operations and Maintenance) to perceive faults on the network side. [0003] The network technology on the AC side for transmitting network side faults may be ATM (Asynchronous Transfer Mode, asynchronous transfer mode) OAM, E-LMI (Ethernet-Local Management Interface, Ethernet local management interface) and so on. Specifically, you can use VCCV-BFD (virtual circuit connectivity detection-bidirectional forwarding detection; Virtual Circuit Connectivity Verification, virtual circuit connectivit...
