1.0 out of 5 stars Get ready to slash your wrists!
Reviewed in the United States on April 20, 2004
This is one of the worst texts I've ever read! The author writes as though the reader totally understands every complex example presented. This is amazing because some parts are very simple and easy to understand. The calculations and formulas are almost to impossible to comprehend. Don't waste your time with this book! There are better, more comprehesive communication networks books out there. This text is by NO means "A First Course"!

4.0 out of 5 stars Don't listen to the students.

As a network professional for the past 6 years, this book was a world of help to me. It was well written and very informative on many aspects of networks today. If you don't or sisn't understand the concepts in this book you need to find another career path. Kudos to Walrand.

5.0 out of 5 stars Very good book
Reviewed in the United States on October 28, 2001
This is a very good book. It strives to give students of networking a broad view of modern communications, along with
the elements of networks. As it also strives to pack all this
into 336 pages, it can be fairly "to-the-point" at certain places. But intelligent readers can fill in the gaps. The book
is not designed to convey the details of say, transport control
but the basics, the most essential points. It succeeds to some
extent on that front. Heartily recommended.

1.0 out of 5 stars DO NOT BUY THIS BOOK!!
Reviewed in the United States on September 29, 2002
this book is absolutely worthless. i actually took a communication class with the author of this book at UC Berkeley, and it is hard for me to decide who's worse: the book or prof. walrand. the entire class hated the book, even the TA's were not able to help us understand it because they didn't understand the book either. this is absolutely the worst book i've ever read. the prof knew the whole class hated him, so he didn't even dare to show up during the finals.
any other book in networking would be better.

Reviewed in the United States on May 31, 2003
Excellent read. The explanations were clear with lots of examples. Teaches network basics as well as intermediate topics. Includes historical facts and future projections.
Highly recommended for beginners and refreshers.

1.0 out of 5 stars North worth the time reading
Reviewed in the United States on February 21, 2000
A very poorly written book. It is not suitable for beginners because it assumes prior knowledge of communication networks. It is also not suitable for network veterans because it is too basic and just touches on a lot of subjects.
Organization: First few chapters will make you wonder how much you were suppose to know to read this book. In the beginning 2 chapters, there is too much jumping around and nothing really gets done. Some concepts are barely mentioned while others, seemingly without reason, are heavily drilled upon. Chapter 3 is heavy on routing algorithm with hard to understand figures. Ch. 4 and 5 are well written on the different LAN's. Suddenly, ch. 6 talks about data link layer. And then ch 7 talks about the layer before that, the physical layer. I couldn't understand this organization. Why not describe each of the 7 layers? Why start from data link and then go down to physical?
Figures and plots: very very hard to understand. Almost cryptic. Sometimes words in the plots to describe a transmission or node do not correspond to the words used in the text.
Text: Concepts are not explained clearly. Having typos that mislead you don't help either. The author assumes that the reader already understand some of the notations used in describing network systems, like notation for sets and binary arithmetics.
On many parts of the text I have read it over 5 times trying to understand the concepts but still gave up at the end. Now I have given up reading the text completely.
