摘要

在本文中,我们首先通过仿真实验评估了IEEE 802.11无线局域网环境下高速和长延迟网络的最新TCP变体的性能。研究表明,其中一些协议在上行和下行流之间仍然具有众所周知的TCP不公平特性,并且由于混合TCP变体的基于损失的行为导致上行流之间存在另一个不公平问题。然后,我们提出了一个端到端的修改TCP拥塞控制机制,以缓解不公平问题,当检测到ACK数据包丢失时激活拥塞控制。通过仿真实验,我们证明了该方法在保证总吞吐量足够大的情况下,既能有效地保证上行流之间的TCP公平性,又能有效地保证上行流和下行流之间的TCP公平性。

Performance Evaluation and Improvement of Hybrid TCP Congestion Control Mechanisms in Wireless LAN Environment
In this paper, we first evaluate the performance of recent TCP variants for high-speed and long-delay networks in IEEE 802.11 wireless LAN environment through simulation experiments. We show that some of them still have well-known TCP unfairness property between uplink and downlink flows, and that there is another unfairness problem among uplink flows caused by the loss-based behavior of hybrid TCP variants. We then propose an end-to-end-basis modification to TCP congestion control mechanisms to alleviate the unfairness problems, which activates the congestion control when detecting ACK packet losses. Through simulation experiments, we present that the proposed method is effective not only for TCP fairness among uplink flows but also for fairness between uplink and downlink flows, while keeping the total throughput to be large enough.
