Abstract
Multipath TCP (MPTCP) enables terminals utilizing multiple interfaces for data transmission simultaneously, which provides better performance and brings many benefits. However, using multiple paths brings some new challenges. The asymmetric parameters among different subflows may cause the out-of-order problem and load imbalance problem, especially in wireless network which has more packet loss. Thus it will significantly degrade the performance of MPTCP. In this paper, we propose a Receive Buffer Pre-division based flow control mechanism (RBP) for MPTCP. RBP divides receive buffer according to the prediction of receive buffer occupancy of each subflow, and controls the data transmission on each subflow using the divided buffer and the number of out-of-order packets, which can significantly improve the performance of MPTCP. We use the NS-3 simulations to verify the performance of our scheme, and the simulation results show that RBP algorithm can significantly increase the global throughput of MPTCP.
