基于Linux的校园网中P2P流量识别及控制

在互联网领域中,分布性的P2P(peer to peer)模式成为了当今网络不可忽视的重要组成部分。所以,准确地识别P2P流量对于保证QoS(Quality of Service)、流量控制、校园网计费管理有着比较重大的意义。通过比较过去的几种技术,文章研究了P2P流量的识别技术,提出了新的识别方法,并在Linux的防火墙Net filter框架下实现有效地控制校园网中P2P流量。

P2P Flow Identification and Control of Linux-based Campus Network

In the Internet field, the distributive P2P （peer to peer） mode has become an important part of today＇ s network. Statistics show that P2P flow accounts for 60% to 85% of the total campus network flow. Sharp increase of P2P flow has led to irrational distribution of network bandwidth and huge loss. Therefore, it is of great significance to accurately identify P2P flow so as to guarantee quality of service, flow control and campus network accounting management. This paper studies the technology of P2P flow identification and puts forward a new identification method based on comparing several techniques in the past, which can be used to achieve effective control of the campus network P2P flow in the Linux firewallNet filter framework.
