摘要

本文研究了光波分复用(WDM)网络中的路由和波长分配问题，提出了一种新的基于权值的边缘不相交路径(EDP)算法来优化波长路由WDM网络中的波长资源。仿真结果表明，网络拓扑特性和链路利用率对流量路由的光路选择有重要影响，以减少所需的波长数。基于权重的RWA解决方案报告了波长利用率的显著提高，特别是对于大型网络，随着对源目标对的呼叫请求的增加。

Weight Based Edge Disjoint Path Routing and Wavelength Assignment (WEDP-RWA) Algorithm for WDM Networks

In this paper the problem of routing and wavelength assignment (RWA) in optical wavelength division multiplexing (WDM) networks has been addressed and a new weight based edge disjoint path (EDP) algorithm for RWA has been proposed to optimize the wavelength resources in a wavelength routed WDM networks. The simulation results reveal that the network topology characteristics and link utilization factor have a significant impact on light path selection for traffic routing to minimize the required number of wavelengths. The weight based RWA solution reports significant improvement in wavelength utilization in particular for large network with increase in the call request for a source destination pair.
