Here are the million-and-one essential details network managers must know, but won't learn in school! The skills of a network manager can literally make or break a company, yet most enter their job completely unprepared. While most schools and references are limited to teaching networking technologies, this Handbook explains life on the line with all the daily operations involved in running a business-scale network, and being a corporate officer at the same time. The author covers everything from strategic planning to documentation, retrofitting, and "managing up."- Written in terms of real platforms, real products, and real budgets- Explains why design is one-half the battle and implementation the other half- Things never covered in the classroom: vendor repair and return policies, calculating "true cost," staff scheduling, downsizing, operating the help desk, asset identification, and more- Thoroughly explains contingency planning, security tactics, purchasing policies, and network integration- Covers LAN and WAN restoration planning

This manual approaches the combination of voice, video and data within the new communications paradigm of IP convergence and examines how these different types of communication will be delivered to any environment from LAN to WAN at much less cost and complexity than either ISDN or ATM. Featuring references to important IP convergence-related Web sites throughout, this book provides comprehensive information on the technologies that will make convergence possible, and it examines the benefits, applications, vendor approaches, migration strategies, and regulatory issues that will affect this new technology. It also covers how IP convergence will affect LAN and WAN networks, and how you communicate at home and in the office. It discusses why implementation of full convergence can happen only when a host of major issues are addressed, including how to place Internet calls to conventional telephones in existing networks and infrastructure improvement and management of Internet call centres.

Providing insight into the operation and application of various Internet technologies, this text explains the technical terms in context and details the appropriate standards. It features over 200 alphabetically arranged topics, short articles, cross-references and illustrations.
