Executive Summary

In this paper, the authors analyze the competition between TCP (Vegas and Reno) and TFRC, and particularly the effect of the transmission delay on the way these protocols share the bandwidth. This study is necessary when they want to design, in future systems, mechanisms to share the bandwidth in a parametrisable way, especially in satellite networks like DVB-S2/RCS allowing Bandwidth on Demand (BoD) assignment. Few performance studies have been published on TFRC and its competition with TCP. Their results show that the fairness is quite variable and is highly dependent on the transmission delay.
