摘要

This paper proposes a novel approach to configure efficient video-on-demand system by introducing Multicast and Cache Video-on-Demand (MCVoD) system. As a key element of the MCVoD system, interchange agent provides this system with multicasting and switching Junctions. With the multicasting, the MCVoD system is able to reduce the load on the network as well as VoD servers by transmitting only one video request instead of sending multiple requests on a same video stream. The switching enables clients to receive the first steam of requested video streams instantly without waiting time and also allows avoiding undesirable duplication of video streams in the system. With various experiment results through simulation about waiting time and cache hit ratio, we show that the MCVoD employing the interchange agent provides better performance than current uni-proxy based system.
