【摘要】 随着下一代智能光网络概念的提出,应用于传统光网络的路由和波长分配方法面临着许多新的挑战。本文以自动交换光网络为代表,分析了智能光网络中不同类型连接的特点和实现路由和波长分配的控制软件模块,并着重从路由模式、多粒度分层选路、路由和波长分配算法、信令路由协议等几个方面出发,对智能光网络中的路由和波长分配问题进行了深入的探讨,同时提出了相应的解决方案。更多还原

【Abstract】 With the introduction of next generation intelligent optical network(ION),routing and wavelength assignment(RWA)problem,which is applied in traditional optical networks,faces many new challenges.Automatically switched optical network(ASON),as the presen-tation of ION,is analyzed in this paper.We analyze the different kinds of connection and RWA control software modules in ION.Then RWA problem in ION is deeply discussed from many aspects,such as routing modes,multi-granularity layered routing,RWA algorithms,signaling and routing protocols.At the same time,the resolving scheme is provided.更多还原
