Problems solved by technology

However, when the ASON channel recovers and returns instantly, because the status of the ASON device cross-connection changes rapidly within a time period of ms level, it cannot be checked through the network management, so there is currently no way to test whether the sending and receiving paths of the ASON channel are consistent

Abstract

The invention discloses a testing method and device for the consistency of automatic exchange optical network channel receiving and sending paths. The testing method and device, provided by the invention, can be used for effectively judging whether the channel receiving and sending paths are consistent or not at the recovering and returning moments of an ASON passage, can be used for project acceptance or running maintenance, and support the actual application of ASON loaded fiber longitudinal differential relay protection technology.

Description

technical field [0001] The invention is a test method and device for the consistency of the sending and receiving path of the automatic switching optical network channel, which belongs to the innovative technology of the testing method and the device for the consistency of the sending and receiving path of the automatic switching optical network channel. Background technique [0002] At present, the power communication transmission network mainly adopts SDH technology. SDH's service protection is based on channel or multiplex section ring protection, which can only defend against N-1 faults, and N-2 faults will cause service channel interruption. Automatically Switched Optical Network (ASON for short) technology realizes dynamic rerouting restoration (referred to as restoration hereinafter) by adding a control plane on the basis of SDH. As long as there is a reachable route between the service source and It can automatically restore service channels and resist multi-point f...
