Abstract

This paper presents a discrete-event systems approach to the modeling of a packet-switched communication link shared by multiple users for the purpose of end-to-end congestion control. It introduces a discrete-event system model for the interaction between a shared communication link and the users, which captures the behavior that the link users receive acknowledgments for successfully transmitted packets with a delay that is proportional to the level of congestion in the link. An end-to-end congestion control scheme for this system model is presented that uses the concept of an observer from supervisory control theory. The link model and controllers are implemented in both a Java programming language simulation and the NS2 network simulation software for analysis.
