Embodiment 1

[0215] Example 1: Combining Figure 10 The flowchart shown, and Figure 11 The interactive flow chart shown in the illustration takes the active / standby status of the active channel and the standby channel as an example to illustrate; among them, in order to be able to Figure 11 Clearly explain the interaction process between the master device and the slave device, Figure 11 Only the numbers of the corresponding steps are shown in .

[0216] S1001. The primary device cuts off the association between the main channel and the Y.1731 terminal, and the association between the standby channel and the Y.1564 terminal;

[0217] S1002. The master-end device sends a notification to the slave-end device that carries the master-standby state that needs to switch the master channel and the standby channel;

[0218] S1003. The slave-end device receives a notification from the master-end device that carries the master-standby state that needs to switch the master channel and the slave ...

Abstract

The invention discloses a method, apparatus and system for switching main and standby channels. A main end device determines whether to switch main and standby states of the main channel and the standby channel or not according to the predetermined performance of the main channel and the standby channel for communicating with a slave end device on one side, wherein the performance of the main channel and the standby channel comprises: channel layer performance and service layer performance of the main channel, and the channel layer performance and service layer performance of the standby channel; therefore in the method, apparatus and system disclosed by the embodiment of the invention, when whether to switch main and standby states of the main channel and the standby channel is judged, the service layer performance is introduced, the service layer performance and the channel layer performance are used as channel selection conditions together, namely, as communication protection switching input conditions, so that the communication protection switching becomes the channel selection of the service, in this way, a communication network can sense the quality requirements of the service, and the service ability and the open ability of the network are greatly improved when the service transmission reliability is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method, device and system for switching between active and standby channels. Background technique [0002] In order to ensure the reliability of business between customers, redundant backup channels are generally provided, that is, standby channels, to avoid problems such as packet loss or service interruption when the main channel fails, and improve service reliability. Such as figure 1 The schematic diagram of the network structure of the private line service is shown. The end-to-end private line service needs to pass through the access layer device 1, the convergence layer device 2 and the core layer device (not shown). Since there will be multiple devices in the middle, the fault point of the network For high-level services, a backup channel must be provided to ensure normal communication between devices; among them, a1 indicates the main channel, and a2 indicates t...
