摘要

路由选择和波长分配是WDM光传输网中非常重要的问题.本文结合交叉连接节点

提出了一种基于最短路径的动态路由选择方案;然后利用这种动态的路由选择策略

以网络的阻塞性能为优化目标分配波长

达到充分利用网络资源的目的.计算机仿真结果表明

无论在单纤或者多纤WDM光传输网络中

利用这种策略的RWA算法优于传统的固定路由和单纯动态路由算法

Abstract

Routing and Wavelength Assignment(RWA) in WDM optical transmission networks is a very important problem.A new RWA strategy is proposed for dynamic Routing and Wavelength Assignment problem in WDM optical transmission networks.Simulation shows these RWA algorithms perform better than some existing ones

which can make full use of networks' resource with lower networks' blocking.
