Abstract - This dissertation addresses Congestion Control for Explicit
Rate-Controlled data networks. Congestion Control is a closed-loop
technique to regulate the influx of data into a network. In the application
considered here, an internal switching node employs Congestion Control
to specify data source input rates such that the traffic arriving at the
node matches the node’s available resources in a fair and efficient manner.
Due to the closed-loop and dynamic nature of this problem, adaptive control
techniques are utilized extensively. The specific context for this
study is the Available Bit Rate (ABR) service category of Asynchronous
Transfer Mode (ATM) networks. However, the obtained results apply
beyond this specific protocol due to the generality of the derived plant
model. It 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, analytically-proven performance
properties, but not so much complexity as to make implementation prohibitively
expensive.
