Experimental Evaluation of Dynamic Switching between One on One and Group Video Calling

It is inefficient to route one-to-one calls WebRTC calls through a media server. Jitsi’s video conferencing architecture utilizes a feature known as Peer-to-Peer for One-to-One (P2P4121) where calls are sent peer-to-peer instead of through the bridge until the third caller joins. This saves on server utilization when it is not needed. George Politis of the Jitsi team gives a review of this capability and the engineering that went into making it.
