Live P2P Streaming System with High Playback Continuity

Abstract- P2P streaming system effectively fixed the overload and weak scalability shortcomings of C/S structures. It’s working principle is divided into tree multicast and mesh multicast. Compared to tree multicast method, mesh multicast method based on Gossip protocol has the characteristics of high fault tolerance and high bandwidth utilization. Gossip multicast in P2P streaming system has become the mainstream. Data transfer of gossip protocols in high-dynamic environment is uncertainty, and the problems of slow start and poor playback smooth, easily happened in streaming media system, will seriously affect the user experience. This paper designs a real-time streaming system DHTPatch, based on the idea of “the capable ones are the busiest”. We organize the nodes with better performance into a DHT network, DHT network can freely and accurately access to resources, make up for the disadvantage of gossip multicast data transmission. The experiment results show that the system not only improves the gossip streaming playback continuity, but also speeds up the streaming startup of the playback.
