A new adaptive transmission mode selection algorithm in hybrid media stream deliver network
Zhang Xingming, Ke Cheng Lin, Shijian Zhang · 2013
Because of the problems of the existing transmission mode for streaming media system that could not guarantee the reception quality of the data while keeping the high distribution efficiency, a new adaptive transmission mode selection algorithm is proposed in this paper. In the algorithm, with a new node state model which divides the node state into data receive quality and consolidated state, the client node selects the transmission mode adaptively based on the existing data buffer model, while the server nodes choose the super nodes to push the data to. The simulation results show that this algorithm enhances the distribution efficiency, while the system scalability is improved under the control of the server load.
