Performance evaluation of a destination-based video distribution strategy for reservation-based multimedia systems

Abstract

We address the issue of minimizing the per user service cost and at the same time maximizing the number of requests that can be served by distributed video-on-reservation (VOR) systems. We propose a heuristic algorithm, destination-based stream scheduling (DBS) algorithm, which combines the concept of multicast routing and network caching with end-to-end delay constraints. Our simulation results show that our algorithm can reduce the service cost, balance the network load and achieve a high acceptance ratio.
