A New Live Streaming Media Architecture for Peer-to-Peer Network

In P2P network, live streaming media distribution in a large scale P2P network and the impact on the real-time caused by the dynamicity of peers are still not well resolved. In order to address this problem, a relative stable P2P network architecture for live streaming media is presented. Our approach is that the architecture combines tree with clusters, and some super-peers are reserved in the clusters for peers´ joining and departure, which is likely to be significant in a highly dynamic environment. In addition, the maximum accepted connection of each super- peer and its average disposing delay are adopted to select the optimal father peer. The experiment results show that the new architecture assures the improvement of real-time and live streaming media distribution in the large-scale P2P network, and at the same time, improves the scalability of the P2P network.
