Adaptive-Push Peer-to-Peer Video Streaming System Based on Dynamic Unstructured Topology

This paper presents an adaptive-push scheme which flexibly applies push method in P2P live streaming system based on unstructured topology. In former P2P streaming systems, push method is hardly adopted in loose topology although it transmits data faster than pull method because the peers are randomly distributed and the aimless pushing will incur great redundancy. To improve P2P live streaming system´s transmitting ability, the proposed scheme improves a mechanical application of the push method in loose topology by designing an adaptive source peer selection strategy. Experiments prove that the proposed scheme is more efficient and robust.
