On Dynamic Control Strategy of QoS in Distributed Multimedia System
分布式多媒体系统的QoS动态控制策略研究

How to achieve dynamic contrl of QoS(Quality of Service)is an important issue in researches on Distributed Multimedia System. This paper, analyzing the principle of QoS dynamic control, presents a dynamic control model of QoS, and discusses following aspects of that model in detail how to represent the parameters and value of QoS, principle of dynamic adjustment, and the implementation of algorithm.
