Acknowledgements

This book has just one author. Despite that, it is only through the efforts of a number of people that this book has now been published.

I would first of all like to thank Patrick Ames. It was he who convinced me to write this book in the first place. Then, having got me to put my ideas down, it was he who helped me find a publisher for my work and he who kept me going, even when I doubted my own ability to complete the project. Without a doubt, this book would not have seen the light of day but for him.

Throughout the writing process, I have received corrections and advice from an array of friends and colleagues. Several engineers and consultants at Juniper Networks provided significant input. Particular thanks go to Aviva Garrett, Paul Goyette, Pete Moyer, Bill Nowak and Todd Regonini, who all provided invaluable technical information. I thank my former colleagues at UUNET, Tony Barber and John Whyte, for their thorough technical review and discussion of various issues covered in the book. I’d also like to thank Danny McPherson, who provided some useful insight into several issues surrounding BGP and the selection of parameters for policy. In addition to the technical reviewers above, Cressi Whyte gave some extremely useful advice on writing style.

I also received great help from Richard Southern of Juniper TAC in checking the configurations at the end of this book. I greatly appreciate the help he gave me at exceptionally short notice. Despite the time constraints, his work was thorough and accurate.

I would also like to thank the editing team at John Wiley & Sons, Ltd: Sally Mortimore, Birgit Gruber, Daniel Gill, Susan Dunsmore and Lucy Bryan.

Finally, I would especially like to thank my wife, Ghillie, and my children, Emily and George, for their endless patience. This book has taken much of my free time and most evenings for several months. I am sorry I have not paid as much attention to you or spent as much time with you as I should have done.
