Acknowledgments

The material presented in this book is based on a compilation of my own practical experiences and those of other members of the networking community. As always, I am solely responsible for any errors in this book. Network analysis, architecture, and design are constantly evolving, and any feedback on how to improve these processes is most welcome. Questions, comments, and suggestions can be sent to me at <[e-mail]> or through Morgan Kaufmann Publishing.

I owe a great deal of thanks to people who reviewed all or part of this book. Dr. Hongwei Du, California State University, Hayward; Robert Hudyma, Ryerson University; Mike Little, NASA; and Norman Patty, BellSouth.

The people at Morgan Kaufmann Publishing have been a wonderful influence on the development of this edition. Many thanks to Dr. David Clark, Series Editor, and to Rick Adams, Karyn Johnson, and Cheri Palmer. I would also like to thank my production editor, Suzanne Kastner, for her patience and understanding throughout.

I also want to thank others who have helped in the development of this book. First, many thanks to Mike Little of NASA Langley Research Center for his insight and direct input to several chapters in this book. In particular, Mike provided a significant amount of new material for the requirements analysis process and has developed a case study that will provided on the Web site.

Thanks also to Eric Garcia at BeamReach Networks for his understanding and help through this long and arduous process. Whether it is tossing around ideas, letting me lean on him for advice, or taking on the burden at BeamReach, Eric has been a tremendous help. Thanks also to Chris Keller and the rest of the Systems Development Group at BeamReach for helping me select the cover for this book, always a trying process.

The chapters on requirements and flow analyses are based on early work on data flow analysis done at the Numerical Aerodynamic Simulation (NAS) facility at NASA Ames Research Center. I owe much thanks to Bruce Blaylock of Cisco Systems, who had the foresight to encourage this work, as well as the tenacity to help see me through the process.

Others who have been instrumental in the development of this book include Kevin Brown, Pierre Catala, Dr. Pisit Charnkeitkong, Alan Mehlenbacher, Mike Minnich, and Keith Nesson.
