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。
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.
