Interested in Network Bandwidth Usage of Audio/Video in Office Communicator !?

Then you should look at the NetMeeting Resource kit as the technologies used by Office Communicator 2005 are thosed offered by NetMeeting (Mainly H.323 and T.120). Chapter 4 also looks at the Firewall configuration and ports used by OC.

Some good information, though determining the bandwidth state is somewhat of a mystery for a MOC user that has never used NetMeeting as their Bandwitdh state is not set, and MOC does not set the NM registry key either. As per extract from Chapter 7...

NetMeeting is configured with the typical bandwidths available on four different network types:

14.4 kilobits per second (Kbps) modem
28.8 Kbps or faster modem
Cable, xDSL, or Integrated Services Digital Network (ISDN)
Local area network (LAN)

The user specifies the network type in NetMeeting

You can set the registry/GPO setting called MaxAVBW -

"If you enable this policy setting, you limit the bandwidth that Communicator 2005 can use for audio and video calls.
If you disable or do not configure this policy setting, Communicator 2005 uses as much bandwidth as is available and necessary for audio and video calls."

Find more info on the setting in "Microsoft Office Communicator 2005 Planning and Deployment Guide"

Thanks Denis - This covers Audio/Video fine, but App Share/Whiteboard has no such controls (other than true color enable/disable), and again what intelligent bandwidth controls are left to a cap are defined in NM, unless MOC uses one of the 4 network types as a default? Also what saving disabling true color brings.
