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流行。然而，考虑到有限的网络和服务器资源以及IP网络的尽力而为性质，网络媒体服务的用户体验仍然远远不能令人满意，特别是在高峰时段。此外，互联网已经发展成为一个超大型和异构的网络。即使是占主导地位的客户端/服务器通信模式也已经转变为与对等通信的混合。因此，我们提出以下关键问题：我们如何能够分发高质量的媒体内容，以大量人口的高度异质性的客户端无缝地通过不同的网络基础设施？
