Abstract

Increasing mass-market acceptance of on-demand streaming services motivates us to seek new innovations in the way we deliver media content over networks. An architecture is proposed in which edge-resources in a peer-to-peer network assist in the provision of fully-interactive on-demand streaming services based on multicast. This approach represents a synergy between multicast batching, proxy prefix caching and collaborative caching of media content. The approach differs from other work in its use of long-term caching of content across streaming sessions. The proposed approach has been evaluated using a highly detailed network simulation that models real-world network (IPv6) and streaming (RTSP) protocols and the Pastry overlay network. Results demonstrate that substantial reductions in server bandwidth can be achieved with low client storage and bandwidth overhead.
