When you enable UDP Multicast for virtual meeting in TrueConf Server web interface the video streams will be transmitted directly from speakers client applications to listeners client applications bypassing the server.
It is achieved by UDP Multicast mechanism the support for which is implemented in many network routers. The essence of this mechanism is that the listeners “subscribe” to video streams of speakers and TrueConf Server just manages this process without passing media traffic.
PLEASE NOTE
UDP Multicast is available only in full version of TrueConf Server.
If your network equipment is not adjusted to work in UDP Multicast environment all conference participants will see a blank screen. Please contact your network administrator for advice.
This mode was created to decrease the load on server web interface and is applicable only for virtual meeting where the number of participants can be up to 250.
To use UDP Multicast you’ll need:
- Activated UDP Multicast option in your license. How to activate this option?
- Network equipment with UDP Multicast support.
