MHealth: A Real-Time Multicast Tree Visualization and Monitoring
MHealth, the Multicast Health Monitor, is a
graphical, near real-time multicast monitoring tool.
By using a combination of application
level protocol data about group participants, and a multicast route tracing
tool for topology information, MHealth is able to discover and display the
full network tree distribution and delivery quality.
MHealth also provides
data logging functionality for the purpose of isolating and analyzing
Logs can be analyzed to provide information
such as receiver lists over time, route
histories and changes, and the location, duration, and frequency of loss.
A paper on the design and development of MHealth will be published
in the NOSSDAV 99 conference proceedings. A gzipped postscript, PDF and
