Example Embodiment

[0026] To realize the automation of fault location, it is necessary to have a complete detection method and a general fault location model after the fault occurs.

[0027] The current fault location mainly relies on manual loopback operations and the experience of maintenance personnel. In the present invention, the veneer, host, and network management team work together to formulate corresponding detection methods according to various failure causes, and then provide the network management with interfaces for these detection methods, and the network management performs further fault location through these interfaces . According to the current interface, there are not many alarm events that can be located, mainly optical fiber signal loss (R_LOS) and some error alarms. Although there are not many alarm events that can be located, if these alarms (such as R_LOS) can be effectively fault location, the efficiency of fault location can still be greatly improved. The general fault loca...

Abstract

A method and system for automatically positioning failure, which contains executing warning relativity analysis to obtain origin resulting in warning, obtaining the all reason resulting in warning, determining whether the failure reason resulting in the failure by matching the practical test result with expected result of test action.

Description

Technical field [0001] The invention relates to a fault management technology in a network, in particular to a method and system for automatically locating faults. Background technique [0002] The SDH signal has abundant segment overhead, which provides strong support for the realization of network operation, maintenance and management. Fault management plays an important role in network maintenance as a means of monitoring network operation status. Due to the abundant segment overhead of SDH, SDH network has abundant alarms for network maintenance personnel to analyze network operation status. However, the occurrence of a fault often leads to a chain of alarms, often causing network maintenance personnel to fall into an alarm storm, and unable to quickly and accurately locate the cause of the fault. Therefore, a solution is needed to enable network maintenance personnel to quickly and effectively troubleshoot the network. Intelligent fault management (IFM) can achieve this goal...
