Enhancing network services and security can be achieved by performing network traffic classification identifying applications, which is one of the primary components of network operations and management. The traditional transport-layer and port-based classification approaches have some limitations in achieving accurate identification. In this paper, a real test bed is used to collect first-hand traffic dataset from five different VoIP and Non-VoIP applications that are used by majority of Internet community, namely Skype, YouTube, Yahoo Messenger, GTalk and PayPal. The collected data encompasses new features that have never been used before. In addition, a classification step is performed using off-the-shelf machine learning techniques, specifically Random Forest J48, meta.AdaBoost (J48) and MultiLayer Perceptron to classify the traffic. Our experimental results show that using the new features can dramatically improve the true positive ratio by up to 98% and this is significant outcome towards providing accurate traffic classification.
