At present, P2P streaming media live systems widely adopt application-layer multicast technology. In order to apply the high performance application-layer model to the live streaming media systems, this paper does research on a scalable and decentralized application-layer multicast infrastructure- Scribe, and then designs a distributed, robust and low-latency streaming media live system based on it. This system is built upon Pastry, a generic, scalable and efficient P2P system, and makes full use of Pastry's properties to form a decentralized, robust and self-organizing overlay network in the ...
