摘要： 采用故障树分析方法对指挥控制系统通信网络的故障传播情况做了详细分析，并对系统各部件的重要度进行了计算．在此基础上，结合指挥控制系统通信网络自身的特点，设计了一种在线监测方案—以Trap为向导的优先级轮询监测方案．最后，利用C++语言在校园网环境下对该监测方案进行了实现．测试结果表明，以Trap为向导的优先级轮询监测方案能够在一定程度上降低网络资源的利用率，提高网络性能．

Abstract: By adopting fault tree analysis．the transmitting of fault in a communication network of C3I system was analyzed detailedly，and the components’ important grades were calculated in this paper Based on the above and combined with the character of a communication network of C3I system．an on-line PR1 polling and monitoring scheme guided by Trap messages was proposed．At last，the scheme was implemented on a campus network by using C ++ languge．Experimental results show that the scheme can decrease the utilance of network resource and increase the performance of network on a certain extent．
