DESCRIPTION
Today, to meet the surging demands of client/server company-wide processes--distributed cooperative computing, business/scientific imaging, video conferencing, multimedia, distance learning and many more--corporations are finding they must extend high-speed communications beyond just a few key sites. This book discusses ATM as the key technology for transforming the enterprise network from data-only to an integrated data, voice, video, image and multimedia corporate infrastructure.
Previous books have covered ATM and client/server separately. This book, intended for networking professionals, is unique in its focus on the hows and whys of the inevitable marriage of these two technologies.
What's inside:
- A description of client/server models and how they function
- A basic review of ATM networking
- Techniques used to build state-of-the-art communications systems
- How to implement a client/server ATM network
- Practical ATM issues such as traffic management and performance
- How to use evolving protocols to grow networks in the future
WHAT THE EXPERTS SAY ABOUT THIS BOOK...
"I will recommend this book to my colleagues ... the book is
excellent."
--Kay Burin, Systems Engineer, Broadband ATM, Hewlett-Packard
"The authors review key concepts with just enough detail
to set the stage for the new information ... but not too much to be
wasting the reader's time ... nice balance."
--Craig Wiesner, Co-founder, WKMN Training
