Executive Summary

The identification of Internet applications is important for ISPs and network administrators to protect the network from unwanted traffic and prioritize some major applications. Statistical methods are widely used since they allow to classify applications according to their statistical signatures. They combine the statistical analysis of flow parameters, such as packet size and inter-packet time, with machine learning techniques. Previous works are mainly based on the packet size and the directions of the packets. In this paper, the authors make a complete study about the interpacket time to prove that it is also a valuable information for the classification of Internet traffic.
