Rule association based alarm correlation in telecommunication management network (TMN)

摘要

In this paper, we present an implemented alarm correlation engine in the alarm correlation and filtering subsystem of the ITRC TMN prototype for SDH network management. This engine uses an algorithm based on the rule association technique for knowledge discovery in large alarm databases. The TMN system uses the produced knowledge in filtering redundant alarms, locating problems in the network, and possibly in predicting the network faults.
