UDP based P2P game traffic classification with transport layer behaviors

Networked game services are very popular in Korea, and game traffic has been increased rapidly around world. Recently, many game applications adapt peer-to-peer (P2P) models especially in UDP based applications. Traditional traffic classification methods are not suitable for these applications due to the limitations. In addition, it is a challenge without examination of payload content. In this paper, we introduce a traffic classification method using transport behaviors for UDP based game applications which use a P2P model. Although our method is quite simple and uses few features, its accuracy is quite remarkable.
