摘　　要：针对EPON系统中上行链路的时分复用机制,提出了一种基于多业务预测的动态带宽分配算法。该算法根据各个优先级业务的实时变化,通过一定的预测机制,实现动态分配带宽。相对其它算法,该算法能在保障高优先级业务优先的同时,降低数据时延。To the upstream TDM mechanism in EPON system, a dynamic bandwidth assignment algorithm based on the multiple traffic prediction is proposed in this paper which can assign bandwidth dynamically according to the change real time of multiple priority traffic based on a certain prediction mechanism. Compare with others algorithms, our algorithm gives preference to higher-priority traffic as well as reduces the time delay of the data.
