中文摘要：
为解决多种粒度光通道所带来的光交换系统中新的故障定位问题,通过对具有多粒度交换能力的光节点进行分析,依据业务请求所建立的光路在节点内以及节点之间的传输路径,提出了信道模型。将二叉树算法应用于该模型中,从而可对不同部件所产生的告警信息进行处理,实现故障的定位。实例仿真计算结果表明,该算法对于故障点的定位精度高、时间短,并且对网络的拓扑没有特殊要求。
英文摘要：
To deal with the problems that this is caused from the multi-granularity light channel in the optical network.The different layers of MG-OXC are analyzed,and the light path of traffic request which are transferred in node or between nodes are also taken into consideration.The channel model is proposed.The binary tree algorithm is applied in the model,thus the alarm which is produced by different part of node can be processed,so the network elements where the fault takes place are located.Results of simulation indicate the fault location algorithm not only immediately detects the fault part with high-precision,but also can apply to any network topology.
