A method for analyzing mutual relation of alarms in a synchronous optical transmission network

摘要

The present invention discloses an alarm correlation analysis method in the synchronous optical transmission network. The present invention is analyzing the alarm correlation between any two nodes which correspond to the alarm that is propagated along the path between the node leading to the downstream node from the upstream node; Alarm correlation between the corresponding effect of the service layer path node with client layer path node (:: Alarm Indication Signal, alarm indication signal AIS) and eseueseu F. (Server Signal Fail, server signal failure SSF) and eyiahyi es in the client layer, It includes the step of analyzing. ; Network alarm correlation analysis method according to the present invention may analyze one of the alarm condition due to the influence of the failure and the multi-alarm upstream to downstream alarms as well as to analyze a variety of alarm information. In addition, network alarm correlation method according to the present invention can improve the efficiency and accuracy of the analysis to effectively overcome the disadvantages of the prior art.
