In P2P media streaming with the pattern of multiple senders and single receiver,it is still a challenge to select multiple senders and optimally allocate streaming rate and media data among multiple senders.To cope with the problem,a new solution(MSRDA) is proposed.Firstly, the problem is modelled as a linear optimization problem,and then the MSRDA algorithm is presented.The MSRDA selects senders according to the sort ascending of selected path’s ratios of packet loss probability to available bandwidth,which is distinct from existing algorithms which select paths only by the packet loss probability of selected paths.Theory analysis and simulation results using NS2 show that the proposed algorithm can effectively reduce the packet loss probability of aggregated bandwidth,dynamically adapt to network fluctuation and achieve a better performance than the related works with different parameters.
