摘　　要：提出了一种基于优先级的波长路由和分配策略。对NSF网络的仿真结果表明,本模型比随机和顺序波长选择的策略具有更优的网络性能,最小的网络阻塞率;当网络负载较低时,波长变化器的使用可以降低网络的阻塞率。The optical network model with and without wavelength conversion was proposed.The Prioritybased wavelength selection strategy was also proposed.We analyzed the performance of some kinds of wavelength routing strategy through NSF network simulation.It is shown that Prioritybased wavelength selection strategy has the best performance and the lowest blocking probability.It is also shown that the wavelength convertor will improve the network performance and decrease the network blocking probability.
