The explosion of P2P file sharing has a significant impact on the Internet. It brings the serious problems such as network congestion and traffic hindrance caused by the excessive occupation in the bandwidth, and the hidden trouble in security. This paper studies the key technologies on traffic identification and control policies. An integrated traffic identification system is proposed, and a prototype model of traffic identification and policy control is designed and presented.
