Thanks to the team at Cisco Press. Thank you Mary Beth for believing in me and to Drew and Mandie for making sure I got things done right and on time. Also thanks to my friend Jim for keeping me in check.

Special thanks to my Cisco Networking Academy family. A big thanks to Jeremy and Rob for involving me in these very cool projects. You guys keep me young.

Finally, a great big thanks to the folks at Cambrian College for letting me have fun and do what I love to do...teach!
