Abstract: In the multi-path parallel transmission process, due to the differences in the quality of the transmission path, the overall performance declines in the network transmission. To overcome this problem, a multi-path parallel transmission path dynamic decision method (concurrent multipath transfer-dynamic selection, CMT-DS) is proposed in this article. Taking into account the influence of path transmission quality on network throughput, by measuring the time delay, jitter, packet loss rate and cache occupancy ratio in the network transmission,the correlation function of the quality of the path is established and the path is selected dynamically based on the correlation function.Experimental results show that the CMT-DS method is more close to the measurement results of the Spirent network test instrument, and the choice of dynamic path improves the network throughput by 12.07%.

Key words: concurrent multipath transfer, quality of path, dynamic selection, network performance
