With rapid and widespread deployment of broadband and wireless communication infrastructures, audio/visual multimedia services are becoming increasingly popular among network users. Yet, given the limited network and server resources, and the best-effort nature of the IP network, the user experience with networked media services is still far from satisfactory, particularly during peak hours. Furthermore, the Internet has evolved into an ultra-large and heterogeneous network. Even the dominant client/server communication paradigm has shifted to a mix with peer-to-peer communications. We thus ask the following critical question: how can we distribute quality media content to a large population of highly heterogeneous clients seamlessly through diverse network infrastructures?
