摘　　要：提出了一种适应于OBS网络的故障监测与定位机制,设计了OBS网络中新的节点模型和突发格式,并采用核心节点向边缘节点发送监测突发的方式,使整个机制尽量少占网络资源。新的定位算法可使故障定位精确到信道一级,并能够估计造成故障的原因。A new mechanism on fault detection and localization in OBS networks is proposed.New structures of node model and burst format are defined to support the mechanism,and additional bandwidth consumption is minimized by allowing only faulty core nodes sending detection bursts to edge routers.The new localization algorithm can not only localize the faults to channel levels,but also estimate the causes of these faults.

关 键 词：光突发交换 故障监测 故障定位
