Abstract: According to the demands about flow management for P2P in IPV6 network, it provides an distributed analysis system of P2P flow-behavior based on IPv6. In the system, the packet capture module is deployed in distribution. The module could collect and make a comprehensive analysis of the flow data from different network monitoring sites. Through experimental comparison, the input of HASH module is optimized, and the efficiency of constructing the flow and maintaining the flow status information is improved. In the system, the behavior characteristics of BT traffic under the real IPv6 network environment is measured and the relative experimental results come out.

摘要： 针对IPV6网络中P2P流量管理的需求，设计了一种基于IPV6的分布式P2P流行为分析系统。该系统的包捕获模块采用分布式部署方式，能实时采集来自于多个网络监测点的流量并进行汇总分析。通过实验对比，系统对HASH模块的输入组合进行优化，解决了IPV6环境下系统建流和维护流状态信息的效率问题。利用该系统在真实IPV6网络环境中对BT流行为特征进行测量，取得了相关实验分析结果。
