TCP Fairness

  • Author(s) / Creator(s)
  • In this project, we focus on the fairness performance of TCP within a simulated WAN environment. Our goal is to understand whether different TCP variants (SACK, CUBIC, HighSpeed, and Westwood) can share the bottleneck link fairly. Specifically, we would like to study the behavior of TCP when two different TCP variants compete with each other over the same bottleneck link. If each of them uses half of the bandwidth of the bottleneck link, then these TCP variants are fair to each other. If one of them consumes more than half of the bandwidth, then the TCP variant is not fair to the other one. Our experiment results show that the TCP variants under investigation are not fair to each other. When two of them compete for bandwidth, one of them always leads to a higher throughput.
