摘　　要：研究了在自相似业务下 ,WDM光网的动态路由和波长分配问题 以阻塞率为判据 ,通过大量的数字仿真试验分析了WDM光网在不同路由策略下 ,相对于自相似业务的Hurst参量和标准偏差参量的动态性能 此外 ,对在泊松业务和自相似业务下的WDM光网的动态性能做了比较 。The dynamic routing and wavelength assignment issues in WDM optical networks are investigated under self-similar traffic for the first time. In terms of blocking probability, numerical simulation results are presented to analyze the dynamic performance versus the Hurst parameter and Variance parameter under different routing schemes. In addition, the dynamic performance is also compared between under the Self-Similar traffic model and under the Poisson traffic model.
