Abstract

In this paper, we design double-mode VoD (video on demand) server (DM-VS). DM-VS provide online on-demand service and offline on-demand service. For offline on-demand service, DM-VS merges several requests accessing the same video clip into a batching multicast that will improve the server´s scalability and resource utilization, and decrease the servicing cost. In this paper, we design the model and scheduling algorithm for DM-VS. We use exclusive resource allocation 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.
