A Machine Learning Approach for Efficient Traffic Classification

Traffic classification is of fundamental importance to track the evolution of network applications and model their behaviours. Further, classified traffic is required to understand how the Internet is being used, and to effectively control the services that traffic receives. In this paper we present a machine-learning approach that accurately classifies live traffic using C4.5 decision tree. By collecting 12 features at the start of the flows, without inspecting the packet payload, our method can identify live traffic of different types of applications with 99.8% total accuracy. Moreover, accuracy is not our only concern; we also consider the latency and throughput as of high importance.
