This textcovers developments in all aspects of Internet and data networks. It includes future aspects of the Local Area Network, Wide Area Networks and the Internet and provides insight into broadband services operated by leading communications companies. With contributions from world-class developers, marketers and vendors, this book gives a balanced view of what customers are demanding and how those demands are being met by a range of data networks and services. Data Network Engineering provides the reader with detailed technical understanding of how networks are actually put together. Topics include the role of services and technologies such as Asynchronous Transfer Mode (ATM), the Switched Multi-megabit Data Service (SMDS), Data Network Security, Internetworking, the Integrated Services Digital Network (ISDN) and Frame Relay, as well as an introduction to the transmission and switching networks such as the Synchronous Digital Hierarchy (SDH) that underpin them. Throughout, the book provides much insight into routers and their development, and includes design rules for building large router-based data networks.This book would be useful to anyone working in the field, for anyone looking for guidance on how data networks are evolving and for all those studying to become the data networking experts of tomorrow.

It is certain that, over the next few years, data traffic will dwarf voice traffic on telecommunications networks. Growth in data-traffic volumes far exceeds that for voice, and is driven by increased use of applications such as e-mail attachments, remote printing and fileserver access, and the now omnipresent World Wide Web. The growth of data networking to connect computers with each other and with their peripheral devices began in earnest in the 1970s, took off in the 1980s and exploded in the 1990s. The early 21st century will see ever faster, more cost­ effective networks providing flexible data access into ever more businesses and homes. Since the 1970s there have been great advances in technology. For the past twenty years the processing power of computers has continued to grow with no hint of slowing - recall the oft-cited Moore's Law claiming that this power doubles every 18 months. Advances in the data networking equipment required to support the data traffic generated have been enormous. The pace of development from early X. 25 and modem technology through to some of the advanced equipment functionality now available is breathtaking - it is sometimes hard to believe that the practical router is barely ten years old! This book provides an overview of the advanced data networking field by bringing together chapters on local area networks, wide area networks and their application.

Data is an increasingly important business asset and enabler for organisational activities. Data quality is a key aspect of data management and failure to understand it increases organisational risk and decreases efficiency and profitability. This book explains data quality management in practical terms, focusing on three key areas - the nature of data in enterprises, the purpose and scope of data quality management, and implementing a data quality management system, in line with ISO 8000-61.
