业务驱动的电力通信网告警–故障关联分析

Service Driven Alarm-Fault Correlation Analysis for Power Communication Network

摘要: 当前电力通信网的传输网络承载了大量的关键业务。因此，其安全稳定运行是保障电力安全的基础。为了使电力通信网由故障事后的被动响应转化为主动的防御，需要一种有效的业务驱动的故障影响分析方案。然而，当前有关研究以网络故障告警关联为主，缺乏面向业务视图的理论支撑和实践工具。因此，为了实现网络故障对业务的影响建模，本文提出了一种业务驱动的电力通信网告警–故障关联分析方法。首先，从业务角度，自底向上构建各层网络之间的相互作用关系模型；之后，构建故障诱因与告警间的风险关联模型，将底层网络故障的诱因影响映射到不同的故障告警发生概率上；之后，构建了告警和业务影响之间的映射模型，最后，基于以上模型架构实现了一套仿真系统，验证了告警–故障关联分析有效性。

Abstract: At present, the power communication network transmission network carries a lot of key services. Therefore, network security and stable operation are to protect the basis of power security. In order to make the power communication network from the fault after the passive response into active defense, there needs an effective fault impact analysis scheme based on service-driven. However, the current research is mainly related to network fault alarms, lacking theoretical support and practical tools for service view. Therefore, in order to implement the modeling of the network fault impact on the services, this paper proposes a service-driven power communication network alarm-fault correlation analysis. First, from the services perspective, we build a bottom-up interaction relationship among different layers of the network. After that, we build a services risk correlation model to map the impact of the underlying network fault roots to different alarm levels. And then a mapping model between alarms and service risks is proposed. Finally, based on the above simulation architecture, a set of simulations system is achieved to verify the effectiveness of the simulation architecture.
