中文摘要：
提出了一种基于网络分割策略的圈覆盖光突发交换网络的故障监测机制,采用网络分割策略,大型的光突发交换网络被分割成便于故障管理的带有中心节点的环形子网或扇形子网,在每个子网内分别执行圈覆盖算法进行故障监测。计算和统计结果表明,该故障监测机制对于节点平均连通度大于3的网络具备网络开销小、故障定位率低等特点。
英文摘要：
The fault detection mechanism based on network partition strategy is proposed in this paper.Firstly,the large-scale optical burst switching（OBS） network is partitioned into several subnet by network partition method,thus the fault monitoring can be achieved by the core nodes in each subnet respectively.Furthermore,with the probe module assigned in each subnet,the network fault can be detected by our cycle cover method.Numerical results show that the fault localization ratio can be improved significantly by our fault detection mechanism for the case of average node degree higher than 3.0;at the same time,the monitor cost can be reduced effectively.
