Providing large-scale true video-on-demand (VoD) service is a challenging problem over the Internet. Some characteristics of the Internet, such as packet switching, best effort mechanism, make it difficult to provide VoD services with enough Quality of Service (QoS) assurance. In this paper, we propose a VoD service model that uses a content delivery network approach on backbone and a peer-to-peer (p2p) approach on access over the Chinas high performance broadband information network (named 3Tnet). We discuss the feasibility of our approach and evaluate the performance by using simulation. The results show that our proposed service model can support true VoD service on the 3Tnet in a scalable way.
