With the growing size and popularity of the Internet, congestion control has emerged as an
important problem. Poor management of congestion can render a network partly or fully …

We analyze Kelly's optimization framework for a rate allocation problem in communication
networks and provide stability conditions with arbitrary fixed communication delays. We …

In this paper, we use a control theoretic approach to develop a generic framework for
analyzing various active queue management (AQM) schemes as proportional-integral …

In this dissertation, we propose a new architecture for Internet congestion control that
decouples the control of congestion from the bandwidth allocation policy. We show that the …

A fluid-based model combined TCP and UDP under RED mechanism has been presented
in this paper based on a previously developed one. We linearized the model and added the …

Today's Internet applications, such as World Wide Web, file transfer, Usenet news, and
remote login, are delivered via Transmission Control Protocol (TCP). With an increasing …

In this paper, we derive a simple first-order discrete-time model for the transmission control
protocol (TCP) with random early detection (RED). We view the network as a discrete …

In this paper, we describe a simple second-order discrete-time model for the transmission
control protocol (TCP) with random early detection (RED) algorithm. The TCP/RED …

This paper focuses on the queue size estimation problem in random early detection (RED)
gateways. Queue size estimation plays a fundamental role in the congestion control …

Recently TCP/RED networks are shown to exhibit a rich set of nonlinear behaviors, leading
to instabilities. In order to address some of these inssues Floyd et al. have proposed an …
