The purpose of Top-Down Network Design, Third Edition, is to help students design networks that meet business and technical goals. This book provides students with tested processes and tools to help them understand traffic flow, protocol behavior, and internetworking technologies. After completing this book, students will be equipped to design enterprise networks that meet requirements for functionality, capacity, performance, availability, scalability, affordability, security, and manageability.


This book is useful for undergraduate and graduate students in computer science and information technology disciplines. Students who have taken one or two courses in networking theory will find Top-Down Network Design, Third Edition, an approachable introduction to the engineering and business issues related to developing real-world networks that solve typical business problems.

Changes for the Third Edition

Networks have changed in many ways since the second edition was published. Many legacy technologies have disappeared and are no longer covered in the book. In addition, modern networks have become multifaceted, providing support for numerous bandwidth-hungry applications and a variety of devices, ranging from smart phones to tablet PCs to high-end servers. Modern users expect the network to be available all the time, from any device, and to let them securely collaborate with coworkers, friends, and family. Networks today support voice, video, high-definition TV, desktop sharing, virtual meetings, online training, virtual reality, and applications that we can’t even imagine that brilliant college students are busily creating in their dorm rooms.

As applications rapidly change and put more demand on networks, the need to teach a systematic approach to network design is even more important than ever. With that need in mind, the third edition has been retooled to make it an ideal textbook for college students. The third edition features review questions and design scenarios at the end of each chapter to help students learn top-down network design.

To address new demands on modern networks, the third edition of Top-Down Network Design also has updated material on the following topics:

  Network redundancy

  Modularity in network designs

  The Cisco SAFE security reference architecture

  The Rapid Spanning Tree Protocol (RSTP)

  Internet Protocol version 6 (IPv6)

  Ethernet scalability options, including 10-Gbps Ethernet and Metro Ethernet

  Network design and management tools
