【摘要】：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。
[Abstract]:In order to solve the problem that the effective throughput of MPTCP is far lower than the total effective bandwidth of each path due to the data disorder in practical application, a method of improving the effective throughput of MPTCP based on delay difference control (CDD-MPTCPP) is proposed. This method reduces end-to-end delay difference between different paths by dynamically adjusting congestion windows on each sub-stream. The simulation results show that CDD-MPTCP can effectively reduce the number of unordered packets received by the receiver without loss of aggregate throughput.
