摘　　要：首先研究了部分波长可变 WDM 网状网中的网络生存性,而后结合分层图模型提出了一种在动态业务情况下的支持不同服务质量(QoS,Quality of Service)要求的路由波长分配算法,仿真结果表明该算法具有很好的性能,提高了全网的资源利用率,满足了客户层业务在建立光通路时不同的 QoS 要求对网络阻塞率的要求。This paper studys the network surviving problem in WDM network with Partial Wavelength Conversion. Based on the layered graph, a routing and wavelength assignment algorithm based on OoS in survivable WDM network is proposed. This results show that this algorithm can not only meet the different QoS requirements of the client layer＇s service, but also utilize the finite networking resources efficiently with the reduced blocking probability.
