Flourishing in the internet: The huge success of live peer-to-peer media streaming

Peer-to-Peer (P2P) media streaming networks have attracted significant research interest recently. However, it is challenging to design live P2P media streaming systems because of the stringent time constraints on the delivered media streams, which require more efficient and resilient overlay. In this paper, we focus on live P2P media streaming networks, a promising application flourishing in the Internet and which requires the distribution of live multimedia content to subscribers. We discuss several live P2P streaming systems, present a basic taxonomy of P2P overlays and closely examine these three approaches, tree-based, mesh-based, tree-mesh-hybrid-based, and summarize the major issues about them. we also categorizes peer selection schemes which are essential for the construction of a P2P streaming network.
