A P2P Tree Model Based on Large-Volume Realtime Streaming Media Transport

By studying the existing P2P tree models, a new RTCP-based P2P algorithm, LrstP2P, is proposed to boost the controllable QoS mechanism of the large-volume realtime streaming media transport. This algorithm has three layers: RTCP Feedback, RTCP Listening and Parent Choice. The LrstP2P enhances the availability of the Parent Choice Strategy for the joining users, improves the self-administration to the unexpectable topology of a dynamical network, improves system reliability and reduces service delay. Experiment data is provided to prove the advantages of the LrstP2P model.
