动态优先级队列能够较好地满足多媒体网络业务流的多种QoS需求。采用离散时间的D-MAP/PH/1排队模型来研究动态优先级队列,并应用矩阵分析的方法,对该排队模型的稳态分布进行分析,得到了系统的主要性能指标:两类业务流的平均队长、阻塞概率和平均延时等结果。
Dynamic priority queue can meet the various QoS requirements of the traffic in multimedia networks. Discrete time queue model was applied in the study of dynamic priority queue in multimedia networks. The steadystate distribution of the queue was analysed by using method of matrix analysis, and the main performance measure were obtained such as average queue length, blocking probability and average delay time of the two traffic.
