摘　　要：对常见的主要Qos调度算法进行了评述,着重介绍了WFQ系列、DRR和CBQ的工作机理,并对WFQ系列进行了理论分析。最后给出比较结果和适用范围,展望了发展方向。Scheduling algorithms is very important for IP Qos mechanism. Most of researches on scheduling algorithms are round robin or GPS based.The recent developments of scheduling algorithms are introduced.The emphasis of the paper is to introduce the classification of scheduling algorithm and analyse the operating mechanisms of three typical implements of scheduling algorifhm: WFQ series, DRR and CBQ.
