Microsoft Windows Official Website where, and I can t find it!. 30 We don t addres s the problem of connectionless scaling because this isn t strictly an architec-. tural problem, although the structure presented here facilitates a solution. PREFACE xxix In 7, The Networ k IPC Model, we do the unpleasant task of assembling all the pieces we have uncovered in the previous six chapters into the elements of the new model and consider its operation. This entails emulating Johnson s harmless drudge as we define all the concepts required. Messy work, but it has to be done.

We consider how new nodes join a network and how communication is initiated. 8, Making Address Topological, returns us to naming and addressing to consider the problem of what location dependent means and how to make useful sense of the concept. In 9, Multihoming, Multicast, and Mobility, we look at how multihoming, mobility, and multicast/anycast are represented in this model and some new results that are a consequence of this model.

In 10, Backing Out of a Blind Alley, we take stock, consider the process that led to seven fundamental issues going unsolved for more than a quarter century, and look to the future.. Acknowledgments This Preface can t end without expressing my immense appreciation to the long list of people who have contributed their time and effort to this book and to my thinking, all of the people whose ear I have bent over the years working through these ideas. The list in its entirety is far too long, but let me hit the high points: Sue Hares, Lyman Chapin, Margaret Loper, Charles Wade, Glenn Kowack, Geneva Belford, Fred Goldstein, George Schimmel, William Zimmer, Sue Rudd, Chris Williams, Fernando Gont, Sharon Day, and a special thanks to Lynn DeNoia for asking the important questions. The reviewers and friends who had to endure so much: Jonathan Smith, Michael O Dell, Pekka Nikkander, Ibrahim Matta, Tony Jeffree, and Joel Halpern.

Catherine Nolan, Mark Taub, Keith Cline, and Chuck Toporek at Prentice Hall for tackling a different kind of book. And of course, my wife, Meg, whose love and support sustained me throughout this project (although, I think she was never quite sure it would ever end). John Day, Lake Massapoag, 2007.

About the Author John Day has been involved in research and development of computer networks since 1970, when they were 12th node on the Net. Mr. Day has developed and designed protocols for everything from the data link layer to the application layer.

Also making fundamental contributions to research on distributed databases, he developed one of two fundamental algorithms in the updating of multiple copies. He also did work on the early development of supercomputers and was a member of a development team on three operating systems. Mr.

Day was an early advocate of the use of Formal Description Techniques (FDTs) for protocols and shepherded the development of the three international standard FDTs: Estelle, LOTOS, and extending SDL. Mr. Day managed the development of the OSI reference model, naming and addressing, and a major contributor to the upper-layer architecture; he also chaired the US ANSI committee for OSI Architecture and was a member of the Internet Research Task Force s Name Space Research Group.

He has been a major contributor to the development of network management architecture, working in the area since 1984 defining the fundamental architecture currently prevalent and designing high-performance implementations; and in the mid-1980s, he was involved in fielding a network management system, 10 years ahead of comparable systems. Recently, Mr. Day has turned his attention to the fundamentals of network architectures and their implications (as discussed in this book).

Mr. Day is also a recognized scholar in the history of cartography, on Neolithic Korea, and on Jesuits in 17th-century China. Most recently, Mr.

Day has also contributed to exhibits at the Smithsonian and a forthcoming chapter in Matteo Ricci Cartographia..
