Abstract

An admission control algorithm is a very important component in a video server that can services large number clients simultaneously. Given the real-time requirements of each client and the fixed data transfer bandwidth, a VOD server must employ admission control algorithms to determine whether or not a new request can be admitted to the server without violating the requirements of the clients already being serviced. All prior admission control policies for VOD servers have focused on improving the storage system utilization such that a video server can service more users while satisfying the QoS requirements. For VOD service, the users can only view the video through transmission networks, so the transmission of video stream in the transmission networks is also very important. The admission control scheme presented in this paper is divided into two layers: disk subsystem admission control and network subsystem admission control. Through simulation, our admission control algorithm outperforms others significantly.
