A critique of atm from a data communications perspective

Abstract

Fast Packet Switching (FPS) is emerging as the preferred technology for future high speed, integrated networks. Asynchronous Transfer Mode (ATM) is an approach to FPS that is in the process of standardization and is the preferred approach of the carrier community. Concurrently, alternative approaches to FPS based on variable sized packets have been proposed by segments of the data communication industry. These approaches include Frame Relay and an approach developed by IBM called PARIS. The purpose of this paper is to examine the suitability of ATM for data communications relative to some of these alternative approaches. © 1992 IOS Press. All rights reserved.
