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.
