摘　　要：此文在的研究领域内,讨论了广域骨干网上区分服务()体系协议的拥塞控制策略。首先分析了拥塞程度的几IP QoSIPDiffServIPIP个等级,其次归纳了体系协议中种标准化的逐跳行为,然后构建了种优先级队列结构,并以此为基础,讨论和分析了相对应DiffServ4PHB4的拥塞控制机制,并认真分析了其机制所采用的算法。In the research field of IP QoS,this paper discusses a system agreement on DiffServ of IP congestion control policy on IP backbone of WAN(wide area network).The paper firsly analyzes several levels of IP congestion extent, and secondly introduces four PHB (per hop behav-iors) standardized in system agreement on DiffServ, and then establishes four structures of priority queue, on this base, discusses and analyzes related IP congestion control mechanism, and its algorithm being used is seriously analyzed.
