An end-to-end guide to the technologies that will enable high-speed networks of the future
Increasingly, end users are demanding that the enterprise network--including LANs, WANs, intranet, VPNs, and the Internet-- functions seamlessly to provide critical business applications and services. Today's networks must be able to accommodate applications that require enormous processing speed and low latency. To ensure your network keeps pace with requirements, you must make it more reliable and predictable, and you must be able to provide more capacity. Paul Izzo puts gigabit standards and technologies in perspective to help you upgrade or build a network capable of handling high-bandwidth needs. Covering technologies from Ethernet to cable modems and DSL, Gigabit Networks will prepare you for enterprise networking in the Internet age.

This book provides practical guidance for combining the gigabit-level technologies that can found throughout most of today's enterprises. The author shows how a network may deliver real-time and advanced applications to the desk top when available technologies are implemented together and maximized. The book educates network designers and administrators on how to evaluate the enabling technologies and walks readers through all the steps of constructing a system that is truly gigabit from end to end and ready to support enterprise applications.
