Information Highways are widely considered as the next generation of high speed communication systems. These highways will be based on emerging Broadband Integrated Services Digital Networks (B-ISDN), which - at least in principle - are envisioned to support not only all the kinds of networking applications known today but also future applications which are not as yet understood fully or even anticipated. Thus, B-ISDNs release networking processes from the limitations which the communications medium has imposed historically. The operational generality stems from the versatility of Asynchronous Transfer Mode (ATM) which is the transfer mode adopted by ITU-T for broadband public ISDN as well as wide area private ISDN. A transfer mode which provides the transmission, multiplexing and switching core that lies at the foundations of a communication network. ATM is designed to integrate existing and future voice, audio, image and data services. Moreover, ATM aims to minimise the complexity of switching and buffer management, to optimise intermediate node processing and buffering and to bound transmission delays. These design objectives are met at high transmission speeds by keeping the basic unit of ATM transmission - the ATM cell - short and of fixed length.

Multi-media networks based on ATM LAN technology can provide integrated transmission of voice, data and visual information direct to the workstation. Such networks are of strategic importance to organisations which depend upon electronic transactions. The smooth operation of these networks is therefore of critical importance. The aim of this special theme is to investigate the state of corporate networks and provide a view of how emerging new technology will improve communications efficiency.

Studies product innovation and firm survival in the U.S. ATM-debit card industry. The industry started with a few shared ATM networks in the early 1970s; the number of networks grew rapidly until the mid 1980s and then declined sharply. A theoretical model is constructed to explain the industry shakeout, A major product innovation -- introducing the point of sale debit function in the mid-1980s -- played an important role in driving the network consolidation. The predictions are tested and confirmed using a novel dataset on network entry, exit, size, location, ownership and product choices. There was little advantage of being early industry entrants; rather, large networks had a better chance to adopt the product innovation and survive the shakeout. Illus.
Asynchronous Transfer Mode (ATM) is a protocol that allows data, sound and video being transferred between independent networks via ISDN links to be supplied to, and interpreted by, the various system protocols. ATM and Internet Protocol explains the working of the ATM and B-ISDN network for readers with a basic understanding of telecommunications. It provides a handy reference to everyone working with ATM who may not require the full standards in detail, but need a comprehensive guide to ATM. A substantial section is devoted to the problems of running IP over ATM and there is some discussion of Frame Relay. A pragmatic introduction to the ATM and IP standards The latest practical approaches to running IP over ATM A comprehensive telecommunications glossary
IFIP TC6 WG6.3 / WG6.4 Fifth International Workshop on Performance Modelling and Evaluation of ATM Networks July 21–23, 1997, Ilkley, UK
Over recent years, a considerable amount of effort has been devoted, both in industry and academia, towards the performance modelling, evaluation and prediction of Asynchronous Transfer Mode (ATM) networks. This book describes recent advances in ATM networks reflecting the state-of-the-art technology and research achievements worldwide. In addition, it provides a fundamental source of reference in the ATM field. Research topics discussed in detail include: Traffic Modelling and Characterisation; Routing; Switch and Multiplexer Models; Call Admission Control (CAC); Congestion Control; Resource Allocation; Quality of Service (QoS); Tools and Techniques. This volume contains recently extended refereed papers of the 5th International Workshop on Performance Modelling and Evaluation of ATM Networks, which was sponsored by the International Federation for Information Processing (IFIP) and held in Ilkley, UK in July 1997. Performance Analysis of ATM Networks continues the tradition established by the first three IFIP volumes on the subject, and it is ideal for personnel in computer/communication industries as well as academic and research staff in computer science and electrical engineering.
