A hybrid peer-to-peer media streaming

In this paper, we present a media streaming service architecture over peer-to-peer network for large scale media streaming service. The proposed architecture is hybrid in that it combines both pure peer-to-peer streaming model and centralized server model in order to take advantages of them. We first describe overall streaming operation based on the hybrid architecture. Then, we deal with streaming load allocation problem under the proposed scheme. Extensive performance study based on simulation is carried out. The results show that the performance of the proposed system is much better than that of existing streaming system in numerous streaming performance metrics.
