摘　　要：针对光突发交换(Optical Burst Switching,OBS)网络在干扰告警信息情况下定位率低的问题,在最短长度m2圈算法的基础上,提出了相应的故障定位机制。首先,故障探测阶段收集由故障触发的告警信息,并组成相应的二进制告警相关矩阵,然后,故障定位阶段利用告警矩阵进行快速定位,找到可能的故障设备集合。Optical Burst Switching （OBS） networks always have lower faulty localization degree with the corrupted alarms, a new fault localization method based on minimum-length probe cycle cover algorithm is proposed. Firstly, the fault detection stage collects the alarms of monitors caused by faulty and generates the corresponding alarm matrix, Secondly, the fault localization stage uses the proposed corresponding alarm matrix to find the possible sets of faulty equipments.
