摘　　要：1.引言自适应QoS技术是随着Internet中多媒体应用需求的不断增加和网络资源的限制而提出和不断发展的.何谓自适应QoS?它可定义为:"在网络资源有限的条件下,以最小的代价.在网络状态变化时,能最大限度满足用户对网络资源的需求,并获得最优的服务质量保证.Many present multimedia applications over High Speed Networks use continuous media such as audio and video. Some distributed multimedia applications now have the ability to adapt to fluctuations in the network by adjusting temporal and spatial quality to available bandwidth, or manipulating the playout time of continuous media in response to variations in delay. This idea of Adaptive control strategy also floods into other fields such as IP Routing, Wireless environment, Differentiated Service, etc. In this paper, we give a brief introduction on Adaptive QoS Management and research application mainly on High Speed Networks.
