The traffic classification is the foundation for many network activities, such as quality of service (QoS), security monitoring, lawful interception, and intrusion detection system (IDS). A recent statistics-based method to address the unsatisfactory results of traditional port-based and payload-based methods has attracted attention. However, the presence of non-informative attributes and noise instances degrade the performance of this method. Thus, to address this problem, in this chapter, a hybrid clustering-classification method (called CluClas) is described to improve the accuracy and efficiency of network traffic classification by selecting informative attributes and representative instances. An extensive empirical study on four traffic data sets shows the effectiveness of the CluClas method.
