Abstract
One purpose of the MBone is to study the performance
of multicast and real-time protocols in global conferencing
applications. Part of this evaluation is dependent on under-
standing how the MBone is used and developing realistic
workloads and usage models to assist in protocol evalua-
tion. We have developed a tool, called Mlisten, to accurately
collect the join/leave times for multicast group members in
MBone audio sessions. Using data collected with Mlisten
and a set of analysis tools, we report statistics about several
MBone audio sessions includingmember inter-arrival times
anddurations, multicasttree routinginformation,and group
spatial characteristics. Data was also collected and ana-
