摘　　要：根据卫星网络拓扑时变性特点及管理域划分策略,提出一种卫星网络故障检测算法。在卫星节点能够响应网管指令的情况下,采用网络管理方法对卫星节点的各个接口进行检测,在卫星节点对网管指令不响应的情况下,启动域内协作或域间协作,通过域内或域间多个卫星上故障检测代理的协作,对疑似故障卫星进行检测。仿真实验结果表明,在故障率较低时,该算法的协作时间短,故障诊断效率高。In terms of the time-varying feature of the satellite network topology and partition policy of the management field in satellite network,the fault detection algorithm of the satellite network is presented.When the satellite can respond to the network management instruction,the network management technique is used to detect the interfaces in the satellite.When the satellite can not respond to the network management,the intra-domain cooperation or inter-domain cooperation is activated.The suspected fault satellite is detected through cooperation among the faulty detection agents in the satellite.Simulation results show that in the circumstance of the low faulty frequency,the algorithm is effectively used in satellite network with short cooperative time and low throughput.
