基于多业务预测的EPON动态带宽分配算法

A EPON dynamic bandwidth assignment algorithm based on the multiple traffic prediction

针对EPON系统中上行链路的时分复用机制,提出了一种支持流量预测与预分机制的动态带宽分配算法(PEM-DBA)。该算法能够对高优先级业务进行流量预测,并根据预测结果预先分配带宽。仿真结果表明,该算法能在保障高优先级业务优的同时,降低数据时延,提高带宽的利用率。

Aiming at the upstream TDM mechanism in EPON system, this paper presented a novel dynamic bandwidth allocation algorithm （PEM-DBA） which supports traffic estimation and bandwidth pre-allocation. The simulation result shows that compare with others algorithms,our algorithm gives preference to higher-priority traffic as well as reduces the time delay of the data and higher bandwidth utilization.
