【摘要】：針對協(xié)議MPTCP在實際應(yīng)用中,因數(shù)據(jù)亂序造成有效吞吐量遠低于各路徑的有效帶寬總和的問題,提出了一種基于時延差控制的MPTCP有效吞吐量提高方法 CDD-MPTCP。該方法通過動態(tài)調(diào)節(jié)各子流上的擁塞窗口來減小不同路徑間的端到端傳輸時延差,以實現(xiàn)減少數(shù)據(jù)包亂序的目的。NS-2仿真實驗表明,CDD-MPTCP可以在不損耗聚合吞吐量的前提下有效減少接收端接收到的亂序數(shù)據(jù)包數(shù)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.
