TCP congestion control over a live UMTS network

We have performed an extensive campaign of measurements that involved around 3000 flows and more than 40 hours of measurements using three different TCP stacks:

  • TCP NewReno: which is the congestion control algorithm standardized by IETF
  • TCP BIC: the default congestion control algorithm adopted by the Linux o.s.
  • TCP Westwood+: available in the Linux kernel (both 2.4 and 2.6 kernels).
