Detection of VoIP Applications in Network Statistics
 Havelka, Ondřej ; Tobola, Jiří (referee) ; Žádník, Martin (advisor)
VoIP applications allow us fast and cheap communication over the internet. Due to the massive expansion of these applications in last few years, there is growth of VoIP traffic, which is needed to distinguish from other traffic. Detection of VoIP applications is related to data monitoring and network traffic classification. The work focuses on detection of these applications: GTalk, ICQ, Skype, WLM a Yahoo. There are presented two detection techniques. First of them is based on behavior of VoIP applications. This technique uses the statistical characteristics of network flows as packet frequency and packet size. The second method is based on searching for patterns in packet contents. These packets carry voice data using protocol RTP. Both techniques were experimentally verified and the results are presented in the work.
