摘　　要：针对目前几种DiffServ(Differentiated Service)网络队列调度算法进行研究,提出一种动态队列调度策略来提高队列转发效率。通过动态调整队列权值实现队列的动态管理,从而改进网络资源的利用效率,改善DiffServ网络QoS。利用NS2模拟动态队列调度算法,实验表明动态队列调度算法有效地提高了区分服务网络的队列转发效率。In this paper we make a study on several queue scheduling algorithms in DiffServ network and put forward a dynamic queue scheduling strategy to improve the efficiency of the queue forwarding.Dynamic queue management is achieved by dynamically adjusting the queue weight so as to have the network resources utilisation improved and the QoS in DiffServ network meliorated.The queue scheduling algorithm is simulated by NS2 and experiment results show that the dynamic queue scheduling algorithm can effectively improve the DiffServ network data forwarding efficiency.
