Competition within the telecommunications companies is growing fiercer by the day. Therefore, it is vital to ensure a high level of quality and reliability within all telecommunications systems in order to guard against faults and the failure of components and network services. Within large scale systems such quality and reliability problems are ever higher. The metrics of Quality and Reliability have to date only been available in journals and technical reports of companies which have designed or produced major parts of systems used in large applications. This book provides a self-contained treatment enabling the reader to be able to produce, define and utilise the metrics of Quality and Reliability required for the design and implementation of a large application such as a world class event as the Olympic Games. An additional outcome is that this book can be used as a guide for producing an ISO standard for large scale Systems such as the Olympic Games. * Provides presentations of techniques used for solving quality and reliability problems in telecommunications networks replete with illustrations of their applications to real-world services and world class events * Individual chapters written by respective international experts within their fields This will prove highly informative for Practising engineers, researchers and telecommunications professionals, academics and graduate students in telecommunications, standards bodies and organisations such as ISO.

"The goal of this thesis is to evaluate the performance of three Asynchronous Transfer Mode switching architectures. After examining many different ATM switching architectures in literature, the three architectures chosen for study were the Knockout switch, the Sunshine switch, and the Helical switch. A discrete-time, event driven system simulator, named ProModel, was used to model the switching behavior of these architectures. Each switching architecture was modeled and studied under at least two design configurations. The performance of the three architectures was then investigated under three different traffic types representative of traffic found in B-ISDN: random, constant bit rate, and bursty. Several key performance parameters were measured and compared between the architectures. This thesis also explored the implementation complexities and fault tolerance of the three selected architectures."--Abstract.

For telecommunications engineers and researchers looking to learn about broadband networks based on the ATM standard, no other book combines the analysis of ATM theory, architecture, and performance in a single volume.

Compiling the most influential papers from the IEICE Transactions in Communications, High-Performance Backbone Network Technology examines critical breakthroughs in the design and provision of effective public service networks in areas including traffic control, telephone service, real-time video transfer, voice and image transmission for a content delivery network (CDN), and Internet access. The contributors explore system structures, experimental prototypes, and field trials that herald the development of new IP networks that offer quality-of-service (QoS), as well as enhanced security, reliability, and function. Offers many hints and guidelines for future research in IP and photonic backbone network technologies

Abstract: "Fast packet switching, also referred to as Asynchronous Transfer Mode (ATM), has emerged as the most appropriate switching technique for future Broadband Integrated Services Digital Networks (B-ISDN). A three-stage banyan-based switch architecture with input and output buffers has been recently described [Chi93]. Such architecture, also referred to as the Memory/Space/Memory (MSM) switching fabric, is capable of meeting the challenges posed by a successful deployment of B-ISDN; namely, it is made nonblocking with low complexity, and is scalable to large sizes (>1000 input/output ports); it supports a wide diversity of traffic patterns, including highly-bursty traffic; it maintains packet sequence, is self-routing, and is simple to operate.

Reflecting the developments in the integrated transport of heterogenous kinds of communication services, this book provides an account of the switching for broadband ATM networks by covering three different areas: the theory of switching; the architecture of ATM switching fabrics; and the performance of the ATM switching fabrics.; The book combines the analysis of ATM theory, architecture and performance and presents the analytical models available to evaluate the traffic performance of ATM switches under random traffic, together with a wide set of results on the traffic performance of each si.
