Reserve-based disk admission control and bandwidth scheduling strategy for continuous media servers

In this paper we present a novel admission control algorithm that exploits the degradability property of continuous media applications to improve the performance of the system. The algorithm is based on setting aside a portion of the resources as reserves and managing it intelligently so that the total utility of the system is enhanced. This reserve-based admission control strategy (RAC) is a compromise between purely greedy and non-greedy strategy, and it leads to an efficient protocol that improves the performance of the system. While the protocol is simple for admission decision, it also results in better performance for the system by reserving some resources for important future applications
