Abstract :
The method for identifying P2P media streaming by traffic features is scalable and suitable for any unknown and encrypted traffic. Some characteristics of P2P media streaming distinguished from P2P file-sharing traffic are provided in this paper, and based on it, the conclusion is gained that the information packets are sent in much higher frequency in P2P media streaming traffic than the file-sharing traffic. Then, the method is proposed that the average value of the ratio of the time in which information packets are transferred to the one in which all data packets transferred of all flows from uploading peers to downloading peer can be used as a metric for identification. The thresholds of this metric are discussed under the measuring model. The experiment shows the feasibility of this metric as well as its thresholds.
