摘　　要：针对WDM光网络中逻辑拓扑的重构迁移问题,提出一种均衡算法,以单条光通道为最小的计算单元,每次选择建立对当前的拓扑性能增益较多而中断的网络资源较少的光通道。仿真结果说明这样的做法有效降低了拓扑重构对网络的影响。This paper presents a balanced algorithm to solve the logical topology reconfiguration migration problem in WDM optical networks. A lightpath which is an all-optical WDM channel is taken as the minimum unit of reconfiguration. The algorithm step by step chooses the lightpath which has more gain and less disrupted network resources to set up. Simulation results show the algorithm can effectively alleviate the influences caused by topology reconfigurations.
