Statistical admission control in video servers with variable bitrate streams and constant time length retrieval

摘要

We consider the admission control problem in video servers for theretrieval of media data from disk storage. We assume that the I/Obandwidth of the server disk is limited. Given a certain I/O bandwidth,admission control decides whether or not a new client can be acceptedwithout affecting the quality of service promised to the alreadyadmitted clients. Assuming variable bit rate (VBR) video streams, weconsider an admission control policy with both, deterministic andstatistical service guarantees for constant time length retrieval (CTL)and evaluate its performance in terms of the number of clients admitted
