From the Inside Flap
This book is designed for management information system (MIS) people, pros and amateurs alike, who want a quick yet accurate summary of network management (NM). What is it? Who should worry about it? And why?
We assume that you know a little, but probably not a lot, about data communications. (If you want to brush up on the basics, refer to the first book in this series: The Basics Book of Information Networking.) We also assume that you and your company have at least some experience with a network and that somebody-maybe you-has a notion that this network could be managed better. Whoever has that notion is probably right.
But network management is a big universe, full of products and processes, and this little book doesn't attempt to cover it all in depth. The Introduction explains where network management came from and points out the aspects that will probably interest you. Chapter 1 defines the broad field of network management and gives an overview of the basic choices that a potential user faces. Chapter 2 describes different communications realms and how management takes place within and across them. Chapter 3 is a brief excursion into Open Systems Interconnection (OSI) and the other kinds of standards that come to bear on network communications. And finally, Chapter 4 puts all of this good knowledge to use, with scenarios for real-life network management.
One suggestion: if you want just a quick introduction to what network management is about, try reading Chapter 4 first. Then, inspired by how logical and accessible NM is, you may want to go back to the earlier chapters for some background. Or, if you come to this book as a fully motivated student of network management, read the chapters in sequence, and consider Chapter 4 your dessert for eating a good dinner in Chapters 1 through 3.
