The All-New Switch Book: The Complete Guide to LAN Switching Technology, Second Edition

Book Description

This much-needed update to the bestselling guide on the extensive changes to the local area networks (LAN) switching technologies explains why LAN switching technologies are critical to network design. This in-depth guide covers the capabilities, application, and design of LAN switches and switched internetworks and examines the significant changes that have taken place since the publication of the first edition seven years ago. You’re sure to appreciate the witty writing style and easy-to-follow format on such an often-complicated subject matter.
