Top-Down Network Design, 3rd Edition presents a systematic, fully practical approach to designing networks.

Thoroughly updated for today's newest technical and business trends, it covers all facets of enterprise network design and all elements of modern enterprise networks.

The authors walk through designing campus networks, data centers, remote access, and wide-area connectivity, and designing for security in an era of wireless networks and mobile users. They also present detailed coverage of performance, reliability, and scalability.

This edition includes new coverage of designing networks that comply with IT Service Management processes, as well as an updated glossary. It also adds chapter-ending essay questions and design scenarios for readers who want to test their understanding of key concepts.
