Abstract

Due to the out of order problem, the goodput is usually far lower than the aggregated throughput. How to improve the goodput is a focus of researches. However, lots of them hardly consider the influence of the congestion window on out of order data. So, based on that, A goodput improvement solution based on controlling delay difference for the MPTCP (referred to as CDD-MPTCP) is put forward. By dynamically adjusting congestion window of each sub-streams, it can reduce end to end path delay, thus reducing out of order data. And, we also propose a data scheduling strategy based on the congestion degree of sub-streams to reduce the congestion during the transmission process. The NS-2 simulation results show that CDD-MPTCP can effectively decrease the amount of out of order data received at the receiver without loss of aggregate throughput.
基于时延差控制的MPTCP性能改进
由于无序问题,货物吞吐量通常远低于聚合吞吐量。如何提高产品质量是研究的热点。然而,许多算法几乎没有考虑拥塞窗口对乱序数据的影响。在此基础上,提出了一种基于时延差控制的MPTCP改进方案(简称CDD-MPTCP)。通过动态调整各子流的拥塞窗口,可以减少端到端路径延迟,从而减少乱序数据。并提出了一种基于子流拥塞程度的数据调度策略,以减少传输过程中的拥塞。NS-2仿真结果表明,CDD-MPTCP可以在不损失总吞吐量的情况下有效地减少接收端接收的乱序数据量。
