对等网络流量检测技术

对等网络(P2P)应用的飞速发展,丰富了互联网的内容,但其流量的爆发式增长和不加限制的带宽占用,不仅给互联网基础设施带来巨大冲击,也给Internet服务提供商(ISP)和应用服务提供商(ASP)的高级服务部署带来了很多问题。开展高效、准确的P2P流量实时识别与过滤相关技术研究,不仅有利于合理利用互联网基础设施、P2P技术和合理部署P2P应用,还有利于制止非法内容在P2P网络中的传播。该文通过对现有P2P流量识别算法进行深入研究和对比分析,为P2P流量有效管理和合理规范提供了技术参考。

Research on the Technology of Peer-to-Peer Network Traffic Identification

The rapid development of Peer-to-Peer (P2P) network has enriched the performance of Internet. However, with the violent increment of data flow and bandwidth using with no restrict, the P2P applications have brought huge impact to Internet base establishment and the advance service of Internet Service Provider (ISP) and Application Service Provider (ASP). Therefore, to utilize the Internet base establishment and P2P technology correctly and to process P2P applications effectively, the technology of P2P network traffic identification and traffic filtering should be researched while restraining the illegal content being transfered in P2P network. This paper focuses on the deep research and comparison of available algorithms of P2P network traffic identification, and gives a technology reference and standard for the P2P network traffic management.
