The role of multicast communication in the provision of scalable and interactive Video-On-Demand service
Multicast delivery can improve the scalability of Video-On-Demand (VOD) systems by allowing multiple customers to share one set of video server and network resources. In such a system, providing customer interactivity can be difficult. In this paper we overview our work which addresses how interactivity may be accomplished in a multicast delivery environment and analyzes the performance of such systems.
