Configuration and Maintenance Manual
Tabl e 4 shows the maximum and peak bandwidth capacity for a single video stream. One
two-party video involves four streams; from each participant to the server and from the server
to each participant. A 200-party conference with only the host broadcasting video involves 200
streams; one from the host to the server and 199 from the server to each participant's computer.
Audio and Web Conference
Audio and Web conference requirements are based on that of an audio-only and Web-only
conference. That is, bandwidth is a significant factor for performance during a Web conference,
and MCA server resources (CPU and memory) used are relatively minimal. Whereas, an audio
conference requires more MCA server resources and has relatively minimal impact to
bandwidth. Capacities of an audio and Web conference are the same as that defined previously
in this section for the conference type.
