MultiPeerCast: A Tree-Mesh-Hybrid P2P Live Streaming Scheme Design and Implementation Based on PeerCast

In this paper, we firstly analyze the mechanism of PeerCast as a P2P live streaming solution. An then, based on the shortcoming analysis of tree-based PeerCast, we propose a improved tree-mesh-hybrid scheme-MultiPeerCast, including Multi-thread media transmission, multiple-to-one overlay network reconstruct, optimized buffer design, media retrieving style changing from push mode to pull mode. As part of experiment work, we discuss an improved P2P live streaming prototype system implementation based on MultiPeerCast. The experiment results verify MultiPeerCast scheme is more stable and efficient than PeerCast. At last, from our research experiences and related survey, we analyze the prospective research direction and challenges in this field.
