Copyvio concerns

When I search on google for a number of phrases within this article, it turns up a page from google books, from the Internetworking Technologies Handbook (Cisco Systems). This seems suspicious. I apparently don't have access to see the page of the book, but I wonder if the last few paragraphs are in violation of the copyright of this book?
