摘要

针对以太网无源光网络（EPON）系统中上行链路的时分复用机制

提出了一种基于最小均方差预测的多队列调度动态带宽分配（DBA）算法。仿真结果表明

该算法可以准确地预测高优先级业务的流量

根据预测结果再合理分配带宽

从根本上避免了轻载惩罚

减小了高优先级业务的延迟。

Abstract

In respect of the upstream TDM mechanism in EPON systems

this paper presents a multi-queue scheduling EPON Dynamic Bandwidth Allocation（DBA） algorithm on the basis of the least mean square prediction.Simulation results show that this scheme can accurately predict the flow of high-priority services and reasonably distribute bandwidth on the basis of the predictions

thus fundamentally avoiding light load penalty and reducing the delay of high priority services.
