Gossip-Based Delay-Sensitive N-to-N Information Dissemination Protocol

This paper presents GConf, a peer-to-peer Gossip-based delay sensitive N-to-N information dissemination protocol, intended for applications such as real-time multiparty conferencing. Through 3-way gossip-based exchanges with randomly selected peers, information frames can be spread throughout the whole community within a delay of 1.5 round-trip-times. The non-delivery probability can be improved exponentially as a function of the peer fanout. Performance evaluations based on a mathematical model and simulations are presented.
