摘要
针对WDM光传送网中的动态路由选择和波长分配(RWA)问题,提出了一种基于遗传算法的动态RWA方法。将遗传算法与相对容量影响(RCI)波长分配算法相结合,以实现对RWA算法的改进。仿真结果表明,与现有最短路径算法[1]相比,该算法能有效提高网络资源利用率,促进波长资源的合理分配。
This paper applies genetic algorithm to the dynamic routing and wavelength assignment problem in wavelength-division multiplexed optical networks.The routing and wavelength assignment algorithm is improved by the combination of genetic algorithm and Relative Capacity Influence algorithm. Simulation shows,compared with shortest algorithms,this algorithm can improve the network utilization and advance the rational assignment of wavelength resource。
