摘　　要：主要依据IEEE802.3ah标准,对EPON当中的动态带宽分配算法进行了探讨,尤其是对于基于轮询的可变周期的带宽分配算法(IPACT算法)进行了一些改进,又结合OPNET的网络仿真工具建立了网络仿真模型,并给出了仿真结果和结果分析。EPON is an important approach to Broad Band and multimedia access. On the basis of the standard of 802.3ah, in this article we mainly discuss the dynamic bandwidth allocation schemes, especially the im- provement based on algorithms of inquiring one-by-one, at the same time we also build up the simulation model and give out the simulation results based on the tool of OPNET.

关 键 词：EP0N 动态带宽分配 带宽利用率 延迟 仿真
