P2P网络技术研究现状与展望

经过多年深入研究和广泛应用，P2P网络技术研究的主要关注方向，已经从过去的P2P协议算法设计分析，转移到P2P系统设计及部署优化、应用扩展和标准化。简要介绍P2P网络技术最近的主要研究进展，包括P2P系统建模与理论分析、CDN}P2P混合式系统、P2P流量控制、网络编码与P2P、扩展应用和标准化，并展望了P2P网络技 术进一步研究和应用部署的主要挑战和发展趋势。

Recent Advances and Trends of Peer-to-Peer Networking Research

After extensive investigations and applications in the past years, the research efforts of Peer-to-Peer(P2P)networking have been turned to the improvement of P2P systems design and deployment, application extension, and standardization, other than the development of P2P protocols and algorithms before. In this survey, we presented recent advances of P2P networking research, including theoretical modeling and analysis of P2P systems, hybrid systems of content delivery network(CDN) and P2P,P2P traffic control,application of network coding to P2P systems,P2P appli- canon extension,and standardization. Finally,we summarized the challenges for further studies and deployment of P2P systems.
