ABSTRACT

In this paper, an improved two-step P2P traffic classification scheme is proposed to overcomethe limitations of the existing methods. The first step is a signature-based classifier at thepacket-level. The second step consists of pattern heuristic rules and a statistics-based classifier atthe flow-level. With pattern heuristic rules, the accuracy can be improved and the amount oftraffic to be classified by statistics-based classifier can be reduced. Based on the analysis ofdifferent decision tree algorithms, the statistics-based classifier is implemented with REPTree. Inaddition, the ensemble algorithm is used to improve the performance of statistics-based classifier. Through the verification with the real datasets, it is shown that our hybrid scheme provides higheraccuracy and lower overhead compared to other existing schemes.
