摘　　要：针对EPON系统上行链路多个ONU共享带宽的拓扑结构 ,本文分析了制定带宽分配策略所需考虑的基本因素 ,在此基础上提出了一种新的动态带宽分配方案 ,通过动态请求分配机制 ,实现上行链路的高效利用。最后 ,通过建模仿真 ,分析了该方案的时延及丢包率特性。This paper investigates design issues of dynamic bandwidth assignment in Ethernet PON system and a novel scheme of requesting-granting by MAC control frame is presented. Furthermore this paper proposes a multiple distribution algorithm based on Ethernet data block. To obtain the realistic simulation result, we generate synthetic traffic that exhibits the properties of self-similarity and long-range dependence. Finally this paper demonstrates and analyzes the network performance under varying offered loads by simulation.
