电力信息网络双通道故障自动探测策略的实现

Implementation of Dual-channel Automatic Fault Detection Strategy in Electric Power Information Network

电力企业的信息网络承载着日常生产办公的重要业务,县级公司至地市公司的信息主干网络一般采用一主一备的双通道模式,遇故障时通道自动倒换成为提高网络可靠性的重要因素。为了解决公司信息网络出现的故障发生时无法识别、倒换的问题,文章通过探寻原因,提出采用网络质量分析(Network Quality Analyzer,NQA)、双向转发检测(Bidirectional Forwarding Detection,BFD)、Track等故障探测策略来解决路由黑洞问题,实现了故障时的自动检测,能够预防由于单点故障造成的网络中断事件。

Power enterprises information network bears the important data service of routine production and office. The backbone information network between county power supply company and city power supply company generally adopts dual-channel for master and backup. Auto switch of the dual-channel is an important factor in improving the network reliability. To solve the problem that the dual-channel can＇t realize auto identification and switch when information network fault occurs, this paper gave an analysis and used NQA（network quality analyzer）, BFD（bidirectional forwarding detection）, Track and some other methods to solve the routing blackhole problem. The automatic breakdown detection was realized which can avoid the network interrupt event when single point failure occurs.
