P2P(Peer-to-Peer)模式为定义高性价比的多媒体流媒体服务提供了颠覆性的市场机会，但同时网络无关的P2P应用在网络效率、运营商经济和用户性能方面也带来了巨大的技术和社会挑战。在终端用户关注质量升级的同时，互联网内容提供商(ICP)更多地考虑服务规模，互联网服务提供商(ISP)更关注运营成本。为了将P2P驯化为更友好的大规模应用，本文从服务提供商、互联网提供商和终端用户三个参与主体的角度提出了一个评估P2P流媒体应用性能的框架。定义了三级绩效指标，从理论上量化了各方的基本关注点，找出了影响服务质量的瓶颈。在处理P2P性能与运营商流量、系统规模与成本、用户服务质量与安全之间的斗争中，作者提出了定义一个前所未有的友好且经济高效的P2P流媒体应用的建议，以实现用户更多、性能更好、成本更低的理想理念。基于学术界和工业界的探索，作者设想将P2P和内容分发网络(CDN)相结合构建一个大规模的流媒体系统，并在我们的评估框架的基础上探索通用的Peer-Server`Peer(PSP)结构的可行性。通过我们的分析研究和产业部署，本文从商业和现实的角度抓住了部署大规模P2P流媒体应用的某些本质，并提出了解决P2P应用与网络运营商之间新出现的紧张关系的多种途径。
Peer-to-peer (P2P) paradigm has provided a disruptive market opportunity to define cost-effective multimedia streaming services, but at the same time network-oblivious P2P applications have been posing substantial technical and social challenges on network efficiency, operator economics and user performance. While end users are concerned with quality upgrade, Internet content provider (ICP) considers more on service scale and Internet service provider (ISP) focuses on operating cost. In taming P2P for a more friendly large-scale application, this paper provides a framework of evaluating the P2P media streaming application performance from perspectives of all entities involved, that is ISP, ICP and end users. Three-level performance metrics are defined, essential concerns of each party are theoretically quantified and bottlenecks in affecting quality service are identified. In handling tussles between P2P performance against ISP traffic, system scale against cost and user QoS against Security, the authors present proposals in defining an unprecedented friendly and cost-effective P2P streaming application to achieve the ideal philosophy of `more users`better performance`lower cost`. Based on the explorations in academy and industry, the authors envision that a large-scale streaming system will be built with a synergy of P2P and content distribution networks (CDN), and explore the feasibility of a general peer`server`peer (PSP) structure on the basis of our evaluation framework. With our analytical study and industrial deployment, this paper captures a certain essence of deploying large-scale P2P streaming application from a commercial and realistic point of view and suggests many avenues for addressing the emerging tensions between P2P application and network operators.
