TCP-friendly congestion control schemes in the Internet

This paper investigates several TCP-friendly congestion control mechanisms and sorts them according to their implementation methods. The advantages and disadvantages of every kind of these TCP-friendly schemes are listed after their principles are outlined. This paper also suggests that a combination of end-to-end mechanisms and hop-by-hop mechanisms is the future of TCP-friendly congestion control as well as a combination of the additive-increase multiplicative-decrease (AIMD)-based scheme and the model-based scheme.
