Acknowledgments

I'd like to thank Brett Bartow with Cisco Press for offering me the privilege of working on this book. Also, thanks to all my CVoice students over the past several years who continually cause me to look at this information in new ways.

A big thank you also goes out to the team of instructors at Thomson NETg. I've never met any instructors more genuinely concerned with helping their students be successful. Of course, that attitude is a direct reflection of our leadership, provided by Tom Warrick and Michael Watkins.

I'm also indebted to the technical editors for this book. Michelle, Anthony, and Larry, I've had the privilege of teaching courses with each of you, and I have tremendous respect for your opinions and insights. Additionally, thanks to my niece, Shayla Brinegar, for her review and feedback on the traffic engineering portion of this book.

On a personal note, undertaking a project of this magnitude would have been unthinkable without the support of my family. My wife Vivian is my biggest cheerleader, while my daughter, Sabrina, and I constantly debate about who loves the other more. Well Sabrina, it's officially in print, I love you more, infinity, period, end of discussion. Meanwhile, my daughter Stacie inspires me with her love of writing. I can't wait to coauthor a book with you someday! I'm so blessed to have you as my family. And, of course, I thank my Heavenly Father for His favor and mercy in my life.
