分布式环形网络故障检测及恢复技术性能分析

在分析DRP分布式环形网络冗余协议故障诊断和恢复机理的基础上,建立DRP故障恢复时间模型,将故障恢复的时间分为故障定位等待时间、故障报警时间和故障处理时间,分别针对交换设备管理模块故障扣通信链路故障,以及DRP方法对不同故障的探测方式,分析影响不同故障恢复时间的各种因素,并根据算法得出制约故障恢复时间提高的主要因素,并通过实验验证各种不同故障在EPA现场网络中故障恢复时间.

Fault Detection and Recovery Technology Performance Analysis of Distributed Ring Network

This paper analysis the fault detection and recovery mechanism of Distributed Redundancy Protocol,a model of DRP fault detection and recovery is established.The fault recovery time is divided into waiting time before fault location,fault warning time,and state transition time.According to characters of the manage module fault in switch and communication link fault,and the difference of the fault detection,all, factors influenced the fault recovery time are analyzed.For different fault,the major factor restricted the improving in fault recovery time is discovered.The fault recovery time of different fault are tested in field test.
