The OSU Scheme for Congestion Avoidance in ATM networks Using Explicit Rate Indication

TL;DR

This paper proposes an explicit rate indication scheme for congestion avoidance in ATM networks that ensures high utilization, fairness, and quick convergence by having sources and switches dynamically adjust data rates based on monitored load.

Contribution

It introduces a novel explicit rate indication scheme with a backward notification option, improving congestion control in ATM networks.

Findings

Achieves high link utilization

Ensures fair rate allocation among sources

Provides quick convergence of congestion control

Abstract

An explicit rate indication scheme for congestion avoidance in computer and telecommunication networks is proposed. The sources monitor their load and provide the information periodically to the switches. The switches, in turn, compute the load level and ask the sources to adjust their rates up or down. The scheme achieves high link utilization, fair allocation of rates among contending sources and provides quick convergence. A backward congestion notification option is also provided. The conditions under which this option is useful are indicated.
