Abstract

There are several network traffic classification methodologies which differ in their assurance and computational complexity. This paper presents a novel network traffic classifier based on Bayesian Classification. This classifier combines the results from three different traffic classification methods, namely, Well Known Ports, Signature Analysis and Support Vector Machines, using a Naïve Bayes technique with data obtained from network inspection. The results are then compared with the results obtained from applying Well Known Ports, Signature Analysis and Machine Learning traffic classification methods individually. The comparison shows that the proposed combined method increases the amount of correctly classified traffic in at least 20% with respect to each individual methodology.
