This book is dedicated to my wife Amita,
And to our beautiful son Jai.
Hardly an Indian love poem, but I'm sure
She understands.

Acknowledgments

As anybody involved in such a large undertaking will attest, attempting to write such a book without feedback is a recipe for insanity. Therefore, I must thank a number of individuals for their time and constructive input on this project. For painstakingly reviewing the content and making numerous suggestions I have Brian Hill of Xyplex to thank. For reviews and helpful suggestions on security and routing topics I must thank my colleagues Philip Miller, Andrew Namboka, and Bob Brace of Nokia Internet Communications; Alex Challis of Asita Technologies; and Derin Mellor. For editing and compiling the final version of this text, I thank Dr. Paul Fortier and Gurukumar Anantharama Sarma of the University of Massachusetts, Dartmouth. I thank Pam Chester and the folks at Digital Press for affording me the opportunity to bring this project to life. Finally, I must thank my wife Amita and my son Jai for their patience and support.

This book does not reflect the policy or the position of any organization I have worked for. No financial support, resources, or direction was obtained from these organizations, and the ideas and opinions presented here (rightly or wrongly) are strictly personal. I apologize for any errors I have made that may offend or mislead. Please forward any constructive input to my e-mail address or to Digital Press.
