Mmdump: A Tool for Monitoring Internet Multimedia Traffic
Internet multimedia traffic is increasing as applications like streaming media and packet telephony grow in popularity. It is important to monitor the volume and characteristics of this traffic, particularly because its behavior in the face of network congestion differs from that of the currently dominant TCP traffic. In order to monitor traffic on a high-speed link for extended periods, it is not practical to blindly capture all packets that traverse the link. The authors' present mmdump, a tool that parses messages from RTSP, H.323 and similar multimedia session control protocols to set up and tear down packet filters as needed to gather traces of multimedia sessions.
