摘要
提出了WDM EPON的一种基于OPNET的建模方法,并且搭建了WDM EPON的仿真平台。在该平台上实现了Online算法,并且分别采用固定服务、限制服务、开门服务三种带宽分配策略进行仿真测试。仿真结果表明在WDM EPON的架构下,Online算法采用开门服务策略会得到较低端到端延时、较高的带宽利用率以及ONU处较小的队列长度。
This paper proposes an modeling approach of WDM EPON based on OPNET, and builts a simulation platform. And further, the online algorithm is achieved on the platform. In simulation, the algorithm adopts three kind of grant scheduling services： fixed service, limited service and gated service. The simulation results show that the algorithm with gated service provides a good performance with a low latency, high band- width utilization and a smaller queue length.
