Very good book/read. The Top Down Approach unique and refreshing, for a networking book.

Great library addition.

Came with the code. That I am grateful for.

I would not agree with another reviewer that this is v7 is simply a reprint of v6 and being sold for higher price. The v6 was published in 2013, and v7 is in 2017. In my perspective the v7 reflected many up-to-date changes that happened during the 3 years. For example, in chapter 2 application, online video streaming is added, and how do Netflix and youtube work are discussed. Chapter 4 network layer are now divided into 2 chapters: the control plane and the data plane, to accommodate the software defined network concept.

In some sense, you will for sure still see many many same pictures and sentences in the v7 as in v6, however, as a new edition, you do not expect it to be a completely new book. There are at least some substantial content update and structure changes in this newer version.

Gets to the point and explains what you need to know about networking, this book is most helpful.
