An admission control framework to support media-streaming over packet-switched networks

This paper presents an admission control framework to support 'streaming' of audio-video data over packet-switched networks. To ensure smooth functioning, the network provides a degree of assurance to the applications in the form of soft QOS guarantees. A measurement based admission control algorithm is developed to enable the network to provide the required service assurances. Sources are characterized using a statistical bounding model, which is fairly universal. A measurement procedure is first developed for online estimation of model parameters. This measurement procedure is then used in the admission control framework. Simulation results are presented and the performance of the algorithms are evaluated.
