Abstract
Fairness and efficiency were, and still are, the center of the most of researches conducted to evaluate the performance of high-speed TCP protocols. The majority of these researches were carried out using two flows. Most of them dealt with Fairness vs round trip time RTT. Some others used several flows but covered only two to three protocols. It may not give a precise idea about Fairness of different protocols and impact performance results. In this paper we propose an evaluation method of Fairness and efficiency for different high-speed protocols: HTCP, HS, Scalable TCP, BIC and CUBIC protocols using multiple flows starting at the same time in the first step, each flow starts at different time in the second one.
