On the effective bandwidth for resource management in ATM networks

Abstract

The aim of this work is to present a synthesis view of the concept and theory of the effective bandwidth, a measure that captures the statistical characteristics of time-varying ATM sources, to cover some of its applications, to investigate its limitations and to determine the extent of its effectiveness. For the effective bandwidth to be a viable tool, its on-line, real-time application to network management tasks is a major concern. In this line of thought, on-line traffic characterization and resource management in ATM networks are the main topics of our work. Since optimal resource management in ATM networks relies essentially on the ability of the network design to perform statistical multiplexing and account for the gains, this case is investigated and a novel, optimal connection admission control (CAC) algorithm is suggested.
