ABSTRACT:
A peer to peer audio communication screen in system with adaptive bandwidth control. The peer-to-peer system can be used, for example, in classroom applications. More interactive peers are moved to a position where they will receive lower latency from the peer-to-peer system. This may be done by maintaining a score indicative of the amount of interactivity, and then using that score to move a peer either close to the source of audio packets, e.g., the core or further from that source.
