Preface In the last few years, the Asynchronous Transfer Mode (ATM) data transmission technique has been promoted as the foundation for the next generation of telecommunication infrastructure worldwide. Fueled by the tremendous expansion of Internet service as well as the strong support by the U.S. government for development of the Information Super Highway in the U.S., a tremendous amount of effort is being spent by the standardization organizations such as ITU-T in Europe and the ATM Forum in the U.S. as well as by the telecommunication industry and the scientific community. As with any other hot and trendy technology development, AT M technology is experiencing certain media hype and being presented as the ultimate technology for the telecommunication infrastructure of the 2151 century. Our main objective in this book is to go beyond the media hype and provide the reader with a more objective and realistic view of ATM technology, its potentials and realistic deployment strategies. Transition to AT M technology will be an evolutionary not a revolutionary process due to the tremendous amount of investment already poured into the current telecommunication infrastructure worldwide. Certainly we cannot afford to switch to a fully ATM-based telecommunication environment overnight. It is our opinion that a significant A TM-based telecommunication infrastructure will take at least a decade to develop. As history indicates, technology alone cannot drive its success unless there is a significant demand for its use and the solution the new technology is providing is economical. Unless ATM technology satisfies these criteria, its fate may not be any different than some of the technologies developed in the last decade, such as N-ISDN. We identify two critical features of ATM technology which will allow it to create necessary market conditions for a large-scale deployment: its ability to allow inter-working of today's several incompatible communication technologies and to provide a high-speed, high bandwidth backbone telecommunication network to satisfy the tremendous demand created by the Internet service. Eventually, we can expect that ATM technology will replace currently deployed multiple telecommunication technologies. The original intent of this book is to provide telecommunication professionals with a compressive view of AT M technology so that they can make a more informed evaluation of the technology in developing their AT M deployment strategies. The book can also be used as a textbook for an advanced undergraduate or graduate course on AT M technology as well as an introduction to broadband telecommunication networks. About the Authors Dr. A. S. Pandya is an associate professor at the Computer Science Department, Florida Atlantic University. He has published over 75 papers and book chapters, and a number of books in the areas of neural networks and learning paradigms. This includes a text published by CRC Press and IEEE Press entitled, "Pattern Recognition using Neural Networks in C++." He consults for several companies including IBM, Motorola, Coulter Industries, and the U.S. Patent Office. He received his undergraduate education at I.I.T., Bombay. He also has a M.S. and a Ph.D. in Computer Science from Syracuse University, New York. Dr. Ercan Sen is a Sr. Product Manager at Siemens Telecom Networks, Boca Raton, Florida. Previously, he has held various engineering staff and supervisory positions at Siemens Telecom Networks. He has over seventeen years of experience in the field of software design for Electronic Telephone Switching systems. He received the B.S. degree in electrical engineering from the Middle East Technical University, Ankara, Turkey, in 1981, and the M.E. and Ph.D. degrees in computer engineering from Florida Atlantic University, Boca Raton, Florida, in 1990 and 1996, respectively. His research interests include neural network applications and high-speed telecommunication networks. He is a member of IEEE since 1982.
