Data and Computer Communications (9th Edition) Review

Average Reviews:

(More customer reviews)For the stated audience -- academics and self-study professionals -- it is hard to envision a better single volume study of datacom principles. Divided into five primary parts (overview, data communications, WANs, LANs, and Networking Protocols), it can provide excellent first course source material to provide a general overview of datacom principles and techniques.
Note that, with as much information as being presented, the book is much more useful as a course text for study than for casual reading. However, it covers sufficient areas to be useful as a reference for the data & computer communications professional. Additional information is maintained by the author on his web site which provides more up-to-date information than can ever be maintained in a printed volume.

Computer Networks, Fifth Edition: A Systems Approach (The Morgan Kaufmann Series in Networking) Review

Average Reviews:

(More customer reviews)A few months ago, I needed to quickly re-educate myself about Weighted Fair Queueing (WFQ). I have a bunch of networking texts on my bookshelf, but I automatically reached for the first edition of Peterson & Davie. I got what I needed: a clear, thorough, yet self-contained discussion. I even got a little extra from the text, which pointed me at other related topics and raised some open problems.
It's true that several of those other books cover WFQ, but I've learned over the last few years that I might as well start with Peterson & Davie, because I usually end up there. They cover almost all of the interesting topics in computer networks, and at just the right level of depth for a quick introduction or refresher. (The authors wrote this as a textbook, and I don't doubt that it would also be an excellent foundation for a graduate level course.) I'm glad to see the second edition, because they've included new material, as well as expanding some of the existing coverage.
This is not the book for exhaustive and definitive coverage of every network protocol; to get a fuller story, readers should turn to the concise list of references cited at the end of each chapter. (In fact, I found at least one mistake in their coverage of HTTP, an example that simply won't work, which is repeated in exercise 24 of chapter 9 -- some students might find this confusing.) But into a book that one can actually lift, Peterson and Davie have crammed a remarkable breadth and depth of detail, written with a clarity often missing from the primary source material.
