The mission of Top-Down Network Design, Second Edition, is to teach a practical methodology for designing enterprise networks that are reliable, secure, and manageable. Like the popular first edition, published by Cisco Press in 1998, this book teaches a network design methodology that is based on structured systems analysis techniques that revolutionized software development projects back in the 1970s and 1980s, now updated to reflect new priorities and technologies.

The book begins by describing the design methodology, as it has been adapted to fit modern network design, with the topics being taught in the order that design tasks should be accomplished. Case studies and examples are included to help the reader understand how to successfully complete a design project that fulfills a customer's requirements. Changes in the business world have resulted in technological adjustments to typical enterprise networks. The author emphasizes design with the following four business needs in mind that are top-priority requirements for network designs: security, resilience, project prioritization based on business goals, and support for mobile users.
