摘要
介绍告警相关性分析及其相关研究,并提出了1个通用的告警相关性分析模型.在分析模型中制定了告警相关性的描述语言和规则发现步骤.基于此,讨论了基于告警相关性分析的通信网故障诊断系统.最后给出了告警相关性分析模型在通信网中实现的前提条件和特点.仿真实验表明,该模型可以压缩冗余告警信息,有利于故障定位.
The analysis of alarm correlation and related researches are introduced. A general alarm correlation model is proposed. Meanwhile the description language and rule discovery processes of alarm correlation are established. Based on the analysis of alarm correlation, the application of fault diagnosis system in telecommunication networks is discussed. Finally the preconditions and characteristics are proposed to realize the alarm correlation model in telecommunication networks. The simulation results showed that the alarm correlation model can compress the redundancy alarms and be benefit to fault location in communication networks.
