A thorough reference for any telecommunications or networking professional who needs to understand the convergence of telephony, data transfer, and wireless communications, from simple descriptions down to the math.

Primarily intended as a text for undergraduate courses in Electronics and Communications Engineering, Computer Science, IT courses, and Computer Applications, this up-to-date and accessible text gives an indepth analysis of data communications and computer networks in an easy-to-read style. Though a new title, it is a completely revised and fully updated version of the author’s earlier book Data Communications. The rapid strides made during the last decade in the fields of data communication and networking, and the close link between these two subjects have prompted the author to add several chapters on computer networks in this text. The book gives a masterly analysis of topics ranging from the principles of data transmission to computer networking applications. It also provides standard protocols, thereby enabling to bridge the gap between theory and practice. What’s more, it correlates the network protocols to the concepts, which are explained with the help of numerous examples to facilitate students’ understanding of the subject. This well-organized text presents the latest developments in the field and details current topics of interest such as Multicasting, MPLS, IPv6, Gigabit Ethernets, IPSec, SSL, Auto-negotiation, Wireless LANs, Network security, Differentiated services, and ADSL. Besides students, the practicing professionals would find the book to be a valuable resource. The book, in its second edition introduces a full chapter on Quality of Service, highlighting the meaning, parameters and functions required for quality of service. This book is recommended in Kaziranga University, Nagaland, IIT Guwahati, Assam and West Bengal University of Technology (WBUT), West Bengal for B.Tech. Key Features • The book is self-contained and student friendly. • The sequential organization lends flexibility in designing courses on the subject. • Large number of examples, diagrams and tables illustrate the concepts discussed in the text. • Numerous exercises (with answers), a list of acronyms, and references to protocol standards.

"Optical communications and fiber technology are fast becoming key solutions for the increasing bandwidth demands of the 21st century. This introductory text provides practicing engineers, managers, and students with a useful guide to the latest developments and future trends of three major technologies: SONET, SDH, and ATM, and a brief introduction to legacy TDM communications systems. There are clear explanations of: * How ATM is mapped onto SONET/SDH * The role of IP networking with ATM * Dense wavelength division multiplexing (DWDM) * The future direction of convergence of communications. This concise book features easy-to-follow illustrations, review questions, worked examples, and valuable references. An accompanying CD-ROM provides the key figures in full color, suitable for easy cut-and-paste presentations. UNDERSTANDING SONET/SDH AND ATM is a must-read for communication professionals who want to improve their knowledge of this emerging technology." Sponsored by: IEEE Communications Society

An essential overview of satellite communications from the organization that sets the international standards Since their introduction in the mid-1960s, satellite communications have grown from a futuristic experiment into an integral part of today's "wired world." Satellite communications are at the core of a global, automatically switched telephony network. Assembled by the International Telecommunication Union--the international organization that sets the standards for this rapidly growing industry--the Handbook on Satellite Communications, Third Edition brings together basic facts about satellite communications as related to the fixed-satellite service (FSS). It covers the main principles, technologies, and operation of equipment in a tutorial form. Updated to include the latest technologies and information, the Third Edition provides both the standards and technical information needed to implement and interact with satellite communication systems, including: * The components and basic characteristics of a satellite communication system * Regulatory considerations and system planning * SDH and ATM satellite transmissions * Analog and digital baseband signal processing and multiplexing * Carrier modulation techniques * Geostationary and non-geostationary systems * Interconnection of satellite and terrestrial networks * LEOS satellite networks and other recent developments As digital modulation and transmission replace analog techniques, and as satellites in non-geostationary and lower-altitude orbits open the way to new applications, satellite communications will continue to grow in use and importance. Everyone involved in the administration and operation of satellite communications will find this a crucial resource.

Beginning with the issue of Vol. 47, No. 2 (April 1998), the full-page edition of Hitachi Review has been available only on...web page in place of the conventional publication.

Network Recovery is the first book to provide detailed information on protecting and restoring communication networks, and it sets a sky-high standard for any that may follow. Inside, you'll learn specific techniques that work at each layer of the networking hierarchy—including optical, SONET-SDH, IP, and MPLS—as well as multi-layer escalation strategies that offer the highest level of protection. The authors begin with an incisive introduction to the issues that define the field of network protection and restoration, and as the book progresses they explain everything you need to know about the relevant protocols, providing theoretical analyses wherever appropriate. If you work for a network-dependent organization, large or small, you'll want to keep Network Recovery within reach at all times.* Shows you how to implement protection and recovery techniques that will save your organization time and money.* Documents techniques for the optical, SONET-SDH, IP, and MPLS layers, as well as multi-layer escalation strategies.* Shows you how to evaluate these techniques in relation to one another, so you can develop an optimal network recovery design.* Provides industry examples and simulation results.* Delves into the inner workings of relevant protocols and offers theoretical analyses wherever this information contributes to your practical knowledge.
