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 example system, however the results of this paper are
applicable to other explicit rate systems as well. After a plant
model is established, 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 contributions in the area of rate-based
congestion control in its balanced approach of retaining enough
complexity as to afford attractive performance properties, but
not so much complexity as to make implementation prohibitively
expensive.
