摘　　要：有效的算法能大大的提高波长利用率,文中研究了WDM光网络在固定路由无波长转换条件下的波长分配算法,以便充分挖掘WDM网络的带宽资源。提出了一种基于RLI并考虑通道优先级的波长分配算法,并给出了该算法的具体实现步骤。最后的仿真结果表明,与RLI算法相比该算法显著的降低了网络的阻塞率,有利于提高网络资源的利用率。An effective algorithm can greatly enhance the wavelength utilization probability.In order to exploit the bandwidth resources of WDM network,we propose a new algorithm based on RLI in the condition that the routing is fixed and there is no wavelength conversion.Then,after fully considering the priority of the wavelength channel,we give the steps of the algorithm.At last,according to the simulation results,we draw the conclusion,that is compared with the RLI,our algorithm significantly reduces the blocking proba-bility of network and promotes the utilization probability of network resources.
