摘　　要：在基于主动探针的网络故障管理中,首要的是确定监测探针的部署。不确定性会对监测探针的选取带来影响。为了降低这种影响,采用概率依赖模型为主动探针选取路由,提出了不确定环境下的监测探针部署方案。利用该方案在网络中部署探针对网络进行主动探测,能以较小的代价尽早定位网络中的故障。实验表明本文的探针选择算法可以有效节约探针开销,且部署的探针集具有较好的故障定位能力。In the network fault management based on active probe, the first job is to determine the deployment of monitoring probe. Non-deterministic environment will impact the monitoring probe selection. In order to reduce the influence, a probe station deployment approach is proposed with select routing for active probe based on probability dependence model. The faults in the network can be localized sooner and cost-effectively using the active probes sent from the probe stations placed in the network. The simulation indicates that the algorithm has strong ability of fault location and cost-effectively.
