摘　　要：通过在几种颇具代表性的网络拓扑结构上进行仿真,对自相似业务在波分复用(WDM)光网络中的动态路由波长分配(RWA)问题进行了研究,分析了自相似业务在不同波长路由分配策略下的动态性能,并与相同条件下的泊松业务作了对比。The dynamic routing and wavelength assignment issues in WDM optical networks under self-similar traffic are studied. Through simulation in three representative network topologies, the dynamic performance analysis of self-similar traffic in WDM optical network is presented. In addition the dynamic performance is compared between self-similar traffic model and the Poisson traffic model under the same condition.
