摘要

提出了一个基于效用的EPON公平性指标算法.通过建立一个基于ACK特征包的ACK压缩和解压缩机制

消除了上游ONU的ACK对下游ONU下行数据流的影响

在保证ONU之间的公平性的同时

提高了带宽的使用效率.通过建立一个效用分类器

在维护了优先级机制扩展性的前提下

提高了并发的同业务类业务流之间的公平性.通过建立一个时延公平调度机制

在保证带宽的使用率前提下

保证了ONU的业务类之间的时延公平性.仿真结果很好验证了本机制的优点.

Abstract

We put forward a utility algorithm on fairness metrics for EPON.By building an ACK compression and decompression mechanism based on ACK-specialized packet

we reduce the ACK interference of upstream ONU on downstream ones

the fairness between ONUs is not only ensured

but also the bandwidth efficiency is increased.By presenting a utility classifier

we improve the fairness among parallel user traffics while keeping the expansibility of priority mechanism.By introducing a delay-fairness scheduling mechanism

we reduce the delay unfairness among a ONU priorities when the bandwidth is not reduced.
