P2P Streaming Traffic Detection in Encrypted Tunnel

The evolution of Internet is continually growing, most people use online streaming applications to watch videos. However, some of P2P streaming applications usually occupy the network bandwidth, and the encrypted tunnel is usually used to avoid the traffic to be detected. Thus, it is an important issue for ISP to detect the traffic in the encrypted tunnel. This paper proposes a novel solution to detect P2P streaming traffic in the encrypted tunnel based on the heartbeat signature of the traffic. The solution finds the heartbeat signature by using the plain-text P2P streaming traffic and detects the traffic in the encrypted tunnel. The true positive rate and the true negative rate of the proposed solution to detect Funshion traffic can reach 93.67% and 100%, respectively.
