Abstract

Abstract

Multicast based stream scheduling algorithm can reduce server and network bandwidth consumption efficiently. But recent studies have indicated that user VCR interactive operations can severely penalize the scalability of these stream protocols. A new stream scheduling scheme, called Regular Multicast Fixed Scheduling (RMFS), is proposed to support interactive playback control in video-on-demand system. RMFS adopts the class-based admission control mechanism to admit client requests and consolidates the unicast stream through stream merging mechanism. The optimal multicast interval, the optimal request threshold and server channel capacity requirements for the RMFS scheme are all analyzed. Extensive simulation results verify the correctness of the analytical model and the feasibility of the presented RMFS.
