摘　　要：基于对爱尔兰(Erlang)业务模型中业务到达时间和业务持续时间生成方法的分析,通过在光网络链路中加入时间戳信息来模拟业务的建立和拆除过程,从而在光网络路由波长分配(Routing and Wavelength Assignment,RWA)算法中建立起一个具体的爱尔兰业务模型;给出基于此模型的光网络首次命中(First-fit)RWA算法流程并进行算法仿真,结果显示模型有效。Based on analyzing the generation way of a service＇s arrival time and its holding time in Erlang service model and by adding time-stamp information to the optical network link to simulate the process of establishment and demolition services, an Erlang service model in optical network routing and wavelength assignment algorithm was proposed. A procedure of First-fit RWA algo- rithm in optical network based on this model was given. The effectiveness of this model was con- firmed by the algorithm simulation.
