Intelligent Distributed Alarm Correlation in Communication Networks

摘要

摘要: 该文提出了智能通信网络的告警相关性分析模型。将通信网按照功能划分成不同的功能子网，针对不同网络的特点，选择适应各自网络特性的告警相关性方法，并建立了层间的网络故障传播模型。提出基于CORBA技术的分布式告警相关性模型。最后，在SDH over DWDM光传送网中，具体分析了告警相关性模型的实现和性能比较。实验证明，采用分布式的告警相关性模型可以有效提高系统的故障诊断水平。

Abstract: 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.
