Nowadays, the performance evaluation of high-speed TCP protocols is the subject of intensive
research. The main criteria used to evaluate the performance are: Fairness, Backward compatibility,
Efficiency, Responsiveness, Scalability, TCP friendliness, and convergence. Most of researches
were conducted to evaluate fairness. The majority of these researches used only two flows in a
Dumbbell topology. Only few papers used several flows. In all cases, to the best of our knowledge,
all flows have the same capacity which may not give an accurate idea about Fairness of different
protocols and impact performance results. We propose an evaluation method of Fairness for
different high-speed protocols: HTCP, HS-TCP, Scalable TCP, BIC-TCP and CUBIC protocols using
multiple flows with the same flow capacity, and with different flow capacities.
