Efficiency, fairness and friendliness evaluation of TFRC and ARC rate-based congestion control

This paper focus on two rate-based congestion control algorithms that have been proposed for streaming flows over the Internet that are the TCP-Friendly Rate Control (TFRC) and the Adaptive Rate Control (ARC). After a brief description of the two algorithms, computer simulations using ns-2 have been reported to investigate intra-protocol fairness, inter-protocol friendliness and efficiency. Main results are: (1) ARC is friendly towards Reno TCP whereas TFRC is not; (2) ARC increases fairness; (3) ARC remarkably improves the goodput with respect to TFRC and Reno TCP in the presence of wireless lossy links.
