DESCRIERE

SDN (Software Defined Networks) and NFV (Network Function Virtualization) are the hottest areas of networking today both in terms of interest and investment, but many professionals do not fully understand what SDN and NFV are, how they work (at a basic level) and why they are so important to the networking industry.

Other books focused on SDN and NFV tend address technical audiences, and information for non-technical people who need only a high level understanding is scant. SDN and NFV Simplified provides both written and illustrated explanations of SDN and NFV (and the underlying virtualizations) concepts using the topic “at-a-glance” approach relevant to the executives, investors, sales professionals and marketers seeking a basic understanding.

The full breadth of SDN and NFV is covered, and the topic flow allows readers to read the book from cover to cover for a comprehensive understanding or pick and choose sub topics to explore as needs or interests dictate. Each chapter will answer the following questions:

Why does the technology matter?
How does it work?
Where is it used?
What problems does it solve?
