A Method on Multimedia Service Traffic Monitoring and Analysis

The use of multimedia service applications is growing rapidly on the Internet. These applications are generating a huge volume of network traffic, which has a great impact on network performance and planning. For various purposes, obtaining information on multimedia service traffic is important. However, traditional analysis methods based on well-known ports cannot be used to analyze such traffic. Because the majority of multimedia service applications use dynamically allocated port numbers, the traditional methods misidentify multimedia service traffic as unknown traffic. This paper presents a method for monitoring and analyzing multimedia service traffic. Our method detects transport protocol and port numbers for dynamically created sessions during a control session. We then use such information to analyze traffic generated by the most popular multimedia service applications, namely Windows Media, RealMedia, Quicktime, SIP and H.323. We also present a system architecture that uses o...
