The book is divided into nine theme-based parts, each with several chapters covering a network concept or technology. Each chapter contains some or all of the following: a part summary, topic at-a-glance pages, and whiteboard illustrations of relevant concepts. The part summary provides a quick and easy introduction to the topic, so you should generally read it first. Useful for future reference are the topic at-a-glance pages, which illustrate core concepts. And the whiteboard illustrations demonstrate important concepts simply and graphically.The flow of this book is a bit different from the first time around. In this edition, we took a building-block approach: Part I: Networking Fundamentals Part II: Networking Infrastructure Part III: Network Design Part IV: Network Availability Part V: Securing the Network Part VI: Data Center and Application Networking Part VII: Unified Communications Part VIII: Mobility Part IX: Virtualized Networks We believe that this approach helps you get from the basics to the more advanced topics more easily. This approach also makes it easier to jump directly into a single topic of interest and understand the big picture. The illustrations and descriptions of the topics serve to answer the primary questions “What is it?”, “Why should I care?”, and “What problems need to be solved?”. We use “big animal” pictures to explain many of the concepts and avoid the temptation to dive into nittygritty details. If you are reading this book, you need to know, for example, what a router does, but not how to actually program one. The second time around, we had as much fun as the first time through writing and illustrating this book. We also had the benefit of experience and are hopeful that we put it to good use. We hope you find this book both useful and entertaining. If it ends up being your primary reference for networking, so much the better.
