摘　　要：互联网正朝着IPv6的方向发展,P2P应用将是推动IPv6产业化的重要力量,但P2P业务在推动Internet宽带化的同时也带来了因资源过度占用而引起的网络拥塞问题和安全隐患。介绍了对等网络的基本概念,讨论了IPv6对P2P的支持功能,总结了应用于IPv6环境的P2P流量识别策略,设计了支持P2P流量识别的IPv6流标签和跳到跳选项,提出了面向IPv6的P2P流量管理模型,并分析了模型的功能组成及工作机制。Internet is evolving in the direction of IPv6, and peer-to-peer （P2P） applications will promote the development of IPv6 industrialization strongly. Besides exploring more available bandwidth, P2P operations also pose the serious problems such as network congestion and traffic hindrance caused by the excessive occupation in bandwidth and hidden trouble in security. Firstly the basic concepts of peer-to-peer networks and the functions ofIPv6 supporting to P2P are introduced. Then the P2P traffic identification policies over IPv6 are proposed and relevant IPv6 flow label and hop-by-hop option are discussed. Lastly a P2P traffic management model is brought forward, and its functional modules and processing are analyzed.
