At last we study the network surviving problem in wdm network with partial wavelength conversion . based on the layered graph , a routing and wavelength assignment algorithm based on qos 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 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qos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 thesis researches on a new scheme of satellite communication with anti - jamming ability , which is a system based on onboard fdma - cwtdm ( continuous wave time division multiplex ) conversion according to the idea of a chinese patent and spread spectrum technique to constitute a mesh network 本文研究一种具有一定抗干扰能力的卫星通信系统，它是根据一项中国发明专利的思想、采用星上fdma - cwtdm (频分多址?连续波时分复用)转换和扩频技术构成无中心网状网的一种卫星通信新体制。
