What type of bandwidth does OCS web conferencing use?

  • 아티클

I had this question from a large school district down in Florida and the answer is it depends on what aspects of the OCS conference you are using.

Here is a bandwidth breakout of the conference scenarios:

 

Application Sharing bandwidth:

Peak Bandwidth Measured in Application Sharing changes as available bandwidth changes.

Desktop Sharing and Remote Control bandwidth

Almost the exact same bandwidth requirements as Application Sharing.

 

VOIP audio conferencing bandwidth

50Kbps to 80Kbps per audio session minimum required

 

Webcam or RoundTable video bandwidth

Basic webcam 50Kbps minimum to 350Kbps maximum per video session

RoundTable panoramic video doubles this requirement to 100Kbps minimum to 700Kbps maximum per video session.

 

Recording Playback

To view a previously recorded Live Meeting session from a server is around 220Kbps.

 

Whiteboard and Poll sessions

Very light weight bandwidth requirements
