中文摘要：

针对目前多路径并行传输过程中,由于传输路径质量的差异会导致网络传输性能整体下降的问题,提出一种多路径并行传输的路径动态决策方法 （concurrent multipath transfer-dynamic selection,CMT-DS）。该方法考虑到路径传输质量对网络吞吐量的影响,通过测量时延、抖动、丢包率、缓存占用比4个路径传输属性,并拟合成路径质量的关联函数,根据该关联函数来对路径进行动态的选择。通过实验验证,结果表明：CMT-DS方法对属性参数测量趋近于Spirent网络测试仪测量结果,对路径动态的选择较其他方法可使得网络吞吐量提高12.07%。

英文摘要：

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%.
