Abstract

One purpose of the MBone is to study the performance of multicast and real-time protocols in global conferencingapplications. Part of this evaluation is dependent on understanding how the MBone is used and developingrealistic workloads and usage models to assist in protocol evaluation. We have developed a tool, called Mlisten,to accurately collect the join/leave times for multicast group members in MBone audio sessions. Using datacollected with Mlisten and a set of analysis tools, we report statistics about several MBone audio sessionsincluding member inter-arrival times and durations, multicast tree routing information, and group spatialcharacteristics. Data was also collected and analyzed for all active sessions to produce information aboutmovement among multicast groups.
