Incremental analysis method of optical synchronization transmission network alarm correlation

Abstract

The invention discloses an incremental analysis method for alarm correlation of an optical synchronous transmission network, which includes the following steps: Step S102, when the path configuration changes or the alarm changes, the analysis data of this time is compared with the analysis data of the last time to obtain Obtaining incremental input data; and step S104 , analyzing and processing according to the incremental input data to determine the root cause alarm, and the derived relationship between the root cause alarm and the non-root cause alarm. The invention can automatically filter out the situation that the non-root alarm is not reported correctly, and further guarantees the accuracy of the analysis.

Description

technical field [0001] The invention relates to a method for locating network faults in the field of optical transport networks. Background technique [0002] With the increasing popularity of the Internet and the continuous improvement of network transmission requirements, both capacity requirements and quality requirements are promoting the continuous advancement of technology. In the network transmission system, the optical network occupies an increasingly important role, and the network fault judgment and solution in the optical network system is undoubtedly an important part of ensuring the quality of the optical network system. In actual network operation, a root failure will lead to a large number of alarm information derived from it. Maintenance personnel need to check the alarm category and location reported by each network element in the network to the network management system, and then combine the network topology relationship and service configuration. Network ...

In actual network operation, a root failure will lead to a large number of alarm information derived from it. Maintenance personnel need to check the alarm category and location reported by each network element in the network to the network management system, and then combine the network topology relationship and service configuration. Network information to determine the root cause of the alarm, and then take the corresponding solution, slow and too dependent on the knowledge and experience of maintenance personnel, poor accuracy and reliability
