Intelligent Distributed Alarm Correlation in Communication Networks
智能分布式通信网告警相关性模型及实现

This paper presents an approach for modeling and solving the problems of intelligent fault identification and alarm correlation in large telecommunication networks. The network is initially divided into its constituting sub-networks. Different correlation technique is utilized in each sub-network according its characteristics. And the fault propagation model is used to model the functional relationship among the sub-networks. At same time, the paper also presents a distributed framework based on CORBA in alarm correlation. Finally the realization and performance of alarm correlation are discussed in SDH over DWDM systems. The experimentation has proved that the fault diagnosis efficiency is prompted by the distributed alarm correlation systems.
