Abstract :
Recent years, the wide spread peer-assisted video-on-demand (VoD) systems have generated a great attention on how to optimize these applications. In particular, how to improve the system performance has become a popular issue. In this paper, we propose how to minimize server bandwidth to satisfy user demand in peer-assisted VoD systems. Furthermore, a linear programming method is presented to calculate the optimal value. We carry out extensive simulation to show how the system performance varies with the change of system parameters. Via comparison, we find conventional peer-selection algorithms, the random algorithm and the greedy algorithm do not perform well. Further work is needed in designing better peer selection algorithms.
