摘要
基于先锋网的天气预报系统对先锋网的可靠性和可管理性提出了要求。分析了先锋网的原理后,我们设计了先锋网故障监测与诊断子系统,并在分析了SNMP下目前故障诊断方法的基础上,提出了主动式的根据各硬件设备的关系收集信息来确定故障源的诊断算法;系统采用以太网与光纤网双型网络,能依据设备之间的关系,经过主动的测试、推断和排除来确定故障的位置,具有很高的智能性,特别是当光纤通路出现故障时,系统还能利用第二条通路进行详细的诊断;系统采用的诊断算法能够根据各部分间的关系对可能出现故障的部分进行主动测试,收集需要的测试信息,从而确定故障源。
The weather forecast system based on Pio-FC switch network ask for high reliability and maintenance from Pio FC net work. The fault monitor and diagnosis subsystem was proposed after the principle of Pio-FC network was analyzed. It adopts Ethernet network and fiber channel network and supports initial and passive monitor and diagnosis, It can monitor communication faults based on the relation of hardware devices by initially testing, deducing and eliminating to locate the place where they occur which stands for high intelligence, especially further diagnosis is still given when faults occur in fiber channel, which improves the reliability and maintenance. Fault diagnosis algorithm can initially test on possible place with faults, collect information and find the source of fault.
