Never has the need for reliable internetworking been greater, yet with networks now comprising differing operating systems, hardware, and software, achieving a reliable network has never been more complex. Network planners and managers face a multitude of difficult decisions-decisions made even more difficult by the need for knowledge from a variety of disciplines. To meet that need, renowned author Gilbert Held assembled a panel of expert practitioners to bring you Network Design: Principles and Applications-a comprehensive, single-source reference for network and IT managers. Beginning with the basics of LANs and WANs, it offers in-depth coverage of modern network planning, design, and optimization. Virtual Private Networks, intranets, and extranets all receive detailed treatment, as do traffic analysis and performance, migration issues, tools, techniques, and network security. Finally, the future of your network and perhaps your job may depend on your knowledge of still evolving network technologies. Network Design: Principles and Applications provides that knowledge with chapters addressing current trends, including IDSL, cable modems, voice and video over LANs, and voice and fax over IP.Network Design: Principles and Applications is one reference that belongs on the shelf of every network and IT manager. The planning and implementation strategies presented will help you create flexible networks that meet performance goals but at the same time allow for the leveraging of new and maturing technologies.
