TLDR
The analysis shows that the mono-window model, which combines flow control and congestion control in a single window, can cause pipe breakdown after packet losses and is not suitable for high-speed and long-delay networks.Abstract:
This paper examines the window mechanism that has been widely used for flow and congestion control. The analysis shows that the mono-window model, which combines flow control and congestion control in a single window, can cause pipe breakdown after packet losses. A dual-window model is then presented, in which flow control and congestion control are decoupled. The dual-window model allows the traffic flow to be sustained while retransmission is being carried out. The dual-window model is particularly suitable for high-speed and long-delay networks where the pipelining of the packets is more crucial. The estimation of the window sizes, advance of the window edges, acknowledgement and retransmission are discussed in detail. Finally the performance of the dual-window model is examined with illustrated examples and by simulation.read more

Control architecture for tuning intensity and burstiness of traffic
Qiong Li,David L. Mills +1 more
TL;DR: A control architecture that can implement active queue management and transport control through the combination of a window and a token bucket that can respond to the two-bit feedback properly is explored.

Congestion avoidance and control
TL;DR: The measurements and the reports of beta testers suggest that the final product is fairly good at dealing with congested conditions on the Internet, and an algorithm recently developed by Phil Karn of Bell Communications Research is described in a soon-to-be-published RFC.

Analysis and simulation of a fair queueing algorithm
TL;DR: In this article, a fair gateway queueing algorithm based on an earlier suggestion by Nagle is proposed to control congestion in datagram networks, based on the idea of fair queueing.

Analysis and simulation of a fair queueing algorithm
TL;DR: It is found that fair queueing provides several important advantages over the usual first-come-first-serve queueing algorithm: fair allocation of bandwidth, lower delay for sources using less than their full share of bandwidth and protection from ill-behaved sources.
