Congestion Control

Abstract--This paper examines congestion control for explicit
rate data networks. The available bit rate (ABR) service category
of asynchronous transfer mode (ATM) networks serves as an ex-
ample system, however, the results of this paper are applicable to
other explicit rate systems as well. After a plant model is estab-
lished, an adaptive control strategy is presented. Several algorithm
enhancements are then introduced. These enhancements reduce
convergence time, improve queue depth management, and reduce
parameter bias. This work differentiates itself from the other con-
tributions in the area of rate-based congestion control in its bal-
anced approach of retaining enough complexity as to afford at-
tractive performance properties, but not so much complexity as to
make implementation prohibitively expensive.
Index Terms--Adaptive control, asynchronous transfer mode
(ATM), available bit rate (ABR), coefficient bias, congestion
