Peer-to-peer real-time group communication over content-centric network

Abstract

Real-time group communication is fundamental to many emerging interactive multimedia applications. Communication among the group members is N-to-N in that any number of group members may generate data and control packets destined to all the other members at the same time. Redundancy Reduction Gossip (RRG) is a highly effective real-time N-to-N dynamic group protocol over the Internet and demonstrates churn and sporadic traffic coping capability. In this paper, a peer-to-peer (P2P) real-time group communication protocol based on RRG is proposed for Content-Centric Network (CCN). A highly effective synergy between RRG and the capability of CCN is exploited. Effects include connectivity expansion, traffic reduction and latency improvement. The proposed protocol allows information distributed from an arbitrary number of dynamic sources in a group. It has low latency and minimal membership maintenance.
