Abstract :
We design double-mode VoD server (DM-VS). DM-VS provides online on-demand service and offline on-demand service. For offline on-demand service, DM-VS merges several requests accessing same video clip into a batching multicast that will improve scalability and resource utilization, and decrease the servicing cost. We design the model and resource scheduling algorithm for DM-VS. We use exclusive resource and different resource scheduling algorithms for the two on-demand services. Besides this, we present the cost functions for online on-demand service and offline on-demand service, and analyze the relation between the two functions.
