Method of VoIP traffic identification based on C4.5 decision tree

This paper proposed a novel method to identify several familiar VoIP traffic based on C4.5 decision tree,which was mainly by select the flow features of classification.It tested the simulated data and the true Internet data.The experimental results show the method achieves high indentification accuracy for the Internet data including many different type of VoIP application,and adapt well for the real Internet data.
