As the wife of an author, you make it without me and still manage to stand by me. 143 47240.book Page iv Friday, July 7, 2006 1:41 PM Acknowledgments Not that a simple acknowledgment is sufficient, but I want to recognize the father of the Street Smarts series, Jeff Kellum. Jeff came to me in the fall of 2005 with his idea. Less than a year later, multiple titles were in the works. I’m sincerely grateful that Jeff considered me for the networking installment in the series. Networking has always been my greatest passion in the computing world. Thanks, Jeff. I’m indebted to Kevin Lundy for keeping me honest in my discussions. A better technical editor I could not have asked for. I’m simply in awe of Sarah Groff-Palermo and Judy Flynn. Their mastery of the English language is a beautiful thing. Of course, all those who work long hours supporting an author and his book I cannot thank enough. My crude drawings come to life in exacting detail. My manuscript is typeset in a professional and alluring style. My work is bound and marketed to the masses. Your exper- tise is necessary, and I appreciate it more than you can know. My gratitude goes out to my Embarq Corporation management team, Rich Hake, Jackie Stecher, and Al Smith, as well as to my colleagues in the Talent Management organization. You constantly challenge me and provide me opportunities for growth. Finally, thank you to my incredible kids, Toby, Tiffani, Trey, and Taylor. You guys support and encourage your dad through your own hard work and determination. You make quite a family. 47240.book Page v Friday, July 7, 2006 1:41 PM About the Author Toby Skandier has been in the networking field since the early 1990s and general computing since the mid-1980s.
