针对协议MPTCP在实际应用中，因数据乱序造成有效吞吐量远低于各路径的有效带宽总和的问题，提出了一种基于时延差控制的MPTCP有效吞吐量提高方法CDD-MPTCP。该方法通过动态调节各子流上的拥塞窗口来减小不同路径间的端到端传输时延差，以实现减少数据包乱序的目的。NS-2仿真实验表明，CDD-MPTCP可以在不损耗聚合吞吐量的前提下有效减少接收端接收到的乱序数据包数量。

The goodput of MPTCP was usually far lower than the aggregated throughput due to out-of-order problem.In terms of this issue,this paper proposed a goodput improvement solution based on controlling the difference of delay for the MPTCP (referred to as CDD-MPTCP).This solution expected to decrease the number of out-of-order packets by dynamically adjusting the congestion window of each subflow and mitigating the variation of end-to-end path delay.The results of NS-2 simulation in-dicate that CDD-MPTCP is able to efficiently reduce the out-of-order packets received at the sink without jeopardizing the ag-gregated throughput.
