theme of our original text book, <a href="https://systemsapproach.org/books/" target="_blank" rel="noreferrer noopener">Computer Networks: A Systems Approach</a>, we are writing a series of books that apply the systems lens to emerging topics (such as 5G, SDN, etc.). With thousands of factoids available on the web (especially when it comes to trending topics), the challenge is to distinguish between what’s important and what’s not; between what’s superficial and what’s lasting.
