This paper describes an end-to-end QoS (Quality of Services) control model for distributed multimedia computing on enhanced Internet, and gives the design and implementation of this model including hosts and routers. The architec- ture, the mathematical definition about QoS parameters, and the mapping between Integrated Service (IS) and Differentiated Service (DS) are discussed in this paper. The simulation shows that this model can improve the performance of audio streams when it is used in IPhone system.
