| Abstract: | Considering the shortcomings of the P2P streaming media technology, which based on the model of the tree topology and extensions and Gossip protocol in media data distribution, the model of P2P streaming media live system based on regionalization is proposed, and a dynamic self-governing regionalization mechanism is used. In a large-scale live streaming media network system, the new model reduces the probability of network congestion, and optimizes bandwidth and latency of the system, while improving the streaming data resource utilization. |
