%X <p>To solve the problem that the coupled congestion control mechanism of multipath transmission control protocol (MPTCP) did not consider the impact of loss rate to the throughput and the traditional static path selection methods did decrease the robustness of parallel data transmission, a dynamic MPTCP path selection method with improving throughput as an optimization target based on Markov decision processes was proposed. This method takes into account the impact of both round trip time and packet loss rate to throughput, chooses different paths based on optimal policy to transfer data but not reduce the number of paths so that it promotes the throughput without reducing the robustness of the parallel data transmission. Simulation shows that the proposed path selection method balances the data stream more effectively and improves the throughput of MPTCP.</p>
