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?

随着宽带和无线通信基础设施的快速和广泛部署，音频/视频多媒体服务在网络用户中变得越来越受欢迎。然而，由于网络和服务器资源有限，以及IP网络的尽力而为的性质，网络媒体服务的用户体验仍然远不能令人满意，特别是在高峰时段。此外，互联网已发展成为超大规模、异构网络。即使是占主导地位的客户端/服务器通信范例也已转变为与点对点通信的混合。因此，我们提出以下关键问题：如何通过不同的网络基础设施将高质量的媒体内容无缝地分发给大量高度异构的客户端？
