Video-on-Demand%Multicast%Emerging-stream algorithm%Dynamic buffering
In local high-speed network, the performance of VOD system is limited by disk-bound. In this paper, we propose an enhanced video-on-demand delivery policy based on dynamic buffering algorithm. Considering the controllable bandwidth allocation for multicast and the characteristics of on-demand video, we optimize the disk access performance of video sever to fully utilize the I/O capability of disk and the bandwidth of network. For a practical VOD system, this strategy can supply instantaneous video-on-demand services and maximum on-demand video number cheaply.
