Summary: AWESOME book on QOS!!!
Review: I am studying for the CCIE R/S lab and it has been very hard to find a good book on QOS until now. I have all the other books from Cisco Press on QOS and I will read them but still don't get it. To me a good technical book is one that takes a complicated subject and makes it simple to understand. This is a great technical book on QOS. This book makes it easy to understand all of the different types of QOS you might come across on the CCIE R/S lab or your DQOS exam. This is by far the best book on Cisco QOS that I have come across.

Summary: Cisco Creates another great Reference
Review: I recently read the book titled "Cisco DQOS Exam Certification Guide" by Wendell Odom, ISBN: 1587200589.
This book takes the user through the topic of Deploying Quality of Service in Cisco networks to a new level of knowledge. QoS has become one of the hottest if not the hottest topic in enterprise and medium size business networks. The ability to control traffic based on its priority and the ability to prioritize the traffic based on any number of criteria has become a required skill in today's marketplace. To Quote from Cisco's Web Site "Quality of Service (QoS) is an essential element to building a flexible, accessible, and efficient network. Its role in multiple technologies underlines the need for most networking professionals to master the features that implement QoS" The advent of Cisco's AVVID network and the proliferation of IP telephone services and applications along with the advancement in Video Conferencing and Group Collaboration software have created an unprecedented need for Quality of Service implementation. This book is filled with examples and thorough explanations of many complicated and essential configurations. The authors display a thorough knowledge of this sometimes difficult and always challenging subject. There are numerous charts and graphs to help aid in understanding the concepts presented. This book takes the reader step by step through configuration of all of the commonly use techniques and gives the user a good understanding of not only how to enter the commands but also what the commands do and how they interact. The topics covered in this book will give a CCIE R/S candidate essentially all of the skills needed for the QoS portions of the CCIE Practical Exam. The book covers all of the currently available traffic prioritization and queuing methods in a high degree of detail. It is, I think, geared towards an audience of knowledgeable professionals who already have some knowledge in the area of QoS. The book provides a reader with the tools necessary to implement virtually any needed QoS features in his/her own network. I would rate it as a MUST HAVE reference for anyone who might be required to implement QoS in a Cisco environment. This is a winner for Cisco Press. It proves once again the commitment to excellence of Cisco Press and delivers a book that is very useful to anyone involved in the implementation of the topic it covers. The authors have taken a difficult subject and broken it down into manageable chunks. At the end of the day the user will have a good understanding of the broad topic of QoS and have the tools necessary to implement it in a Cisco environment.

Summary: A Lot of Information
Review: I recently read the book titled "Cisco DQOS Exam Certification Guide" by Wendell Odom, ISBN:1587200589. Cisco Press recently released this book on August 13, 2003.
This book has the most information, in one source, on Cisco QoS that I have come across. It also has information that is better documented than in other references that I've seen. I think this book is best suited for the Intermediate to Advanced networking professional.
The book is riddled with tables, figures and examples. The author has done a great job presenting the material though text and illustrations to help the reader understand some of the more complex areas of QoS. The amount of content is a bit overwhelming, but so is the topic of QoS itself. This book is exceptionally well written to assist in comprehending most all aspects of QoS.
I attended the Cisco Curriculum Course "Deploying QoS for Enterprise Networks" about a year ago and learned a great deal of information in that course. However, this book seems to expound a bit upon what I learned in class. The book follows the course in its organization, for the most part.
I really like the way the book is organized. It seems to be written in a conceptual format equivalent to the life of a packet. Which helps in the overall understanding of how a packet is processed or handled using QoS.
The book comes with a Compact Disk, which includes a self-study/practice test and the entire book in soft copy form, PDF Format. The self-study/practice test has a total of 200 questions in the pool. The format of the test is identical to the actual certification tests given by the companies that administer the certification test. Coming from a non-test taker, I found the questions to be a little difficult to understand what was being asked. A lot of my misunderstanding had to do with the terminology. It seems that if one is to be successful in passing the test that this book is designed to prepare you for, one key element is to understand the terminology that is used in this book. I'm certainly not fluent in QoS lingo, but I feel accomplished enough to make an installation/application successful. I think I would have great difficulties with the terms used in the practice test. Some of the questions are confusing.
The book has a pretty good section on LAN QoS, but for a better reference on the topic I recommend the book titled "Cisco Catalyst QoS" by Michael Flannagan. For the purposes of the certification it covers a good deal of information on LAN QoS and serves as a pretty good reference on the topic.
I would have like to have seen information pertaining to some of the more recent QoS tools pertaining to the directing of traffic in Frame Relay and ATM environments. It would have been worth noting the Frame-Relay and ATM bundling features and how those features can be leveraged to help with an end-to-end QoS strategy. I think these features are potential alternative solutions to using features such as DLCI priority groups or Policy Based Routing (PBR), which are hard to scale, when making routing decisions based on QoS information.
All in all, this is a great book as study material for the Certification and as a desktop reference

Summary: Great book
Review: It seems that everybody likes this book so I won't waste your time writing another long review.
This book is by far the best Cisco book I've read, and I've read a few. It's full of detail and a very very good starting point for QOS.

Summary: Great resource before and after the exam!!!!!!
Review: Let me just start off by saying that I wish I had Wendell Odom's Cisco DQoS Exam Certification Guide a few months ago when I was studying for this exam. I had looked at a number of other Cisco Press and non-Cisco Press books and could not find one that adequately covered the topics in the exam. This one covers all of them and more. The book starts off by listing all the exam topics that will be covered in both DQoS 9E0-601 and QOS 642-641 exams and then explains how to interpret those often nebulous expectations. Do not get me wrong. It does not give you a blow by blow of what is on the exam but rather informs you of how test makers come up with course objectives and a method to use in studying. I found this very helpful. In fact, I wish someone had taught me that as a freshman in college. If you are familiar with Cisco Press Exam Certification Guides you will not be disappointed in the familiar format. Each chapter starts with an overview and "Do I Know This Already?" quiz. I always find these helpful in determining my level of knowledge on a particular subject and those areas I need to study. It then proceeds to the meat of each chapter. They are filled with many useful diagrams and tables that do a wonderful job complimenting and expanding Odom's covering of each chapter. There are plenty of switch and router configurations that also provide help in giving real life examples of how QoS is implemented. Each chapter then wraps up with an excellent Foundation Summary and Q&A section. Answers to the questions are found in an appendix in the back of the book. In general I found all of the topics covered as well, if not better, than the DQoS class I took to study and pass the test. In particular I found the first two chapters great in providing a great overview of QoS, its architectures and tools. I have used Odom's example of bank teller lines, with a number of customers, to provide a way of explaining the difficult topic of QoS and it quickly resonates with them. I also found the last two chapters on QoS Design and LAN QoS very useful. The LAN QoS chapter provides information on the 3550s and latest Modules/Supervisor Engine cards for the Catalyst 6500 and 4500/4000. I have already used this information as a resource on a project. The design chapter has also been useful in helping me "flesh out" customer's goals and providing design recommendations based upon those goals. In conclusion, I always feel that for a study guide to truly be useful, it must have some use after the exam. Wendell Odom's Cisco DQoS Exam Certification Guide certainly does that well. It will not only be sufficient in providing you the information that you need to study for and pass the test, but it will certainly be useful as a quick reference guide on many of the topics covered. I plan on having it with me from the project planning stages to the optimizing and troubleshooting stages (although if your good and follow his teachings on the former you probably will not have much of the latter). Thanks Wendell for another well written and useful book.

Summary: And the Award for Best of Cert Books goes to....
Review: The team of Cavanaugh & Odom have hit a homerun here. This book has everything; Sex, Politics, Intrigue, Suspense, Greed, Betrayal and Redemption. Well, okay, it has none of that. But, it does have everything that the Experienced Networker could want to know about Quality of Service, and it's role and implementation within today's rapidly converging internetnetworks. The authors have proven to be knowledgeable, insightful and easy to understand. And, while this book may seem "overly long" to many, it strives to give fairly complete coverage of this important matter regarding today's internetworking environment. This is a very important point when your seeking to spend some "quality time" with a Cisco certification exam (not mention some quality cash on an exam).
Cavanaugh & Odom have moved beyond the normal course of just re-editing Cisco TAC web content for bound, portable consumption that is the hallmark of many of Cisco Press' previous publications. While the layout will be familiar to previous C.P. readers, the actual format and content presentation is fresh. Each chapter's order and flow strongly adheres to the tried and true, but Illustrations, Diagrams, Scenarios and Examples are not just simply reprinted fare from Cisco's website. Each chapter's content is easily on par with all other Authors/Publishers that are typically quoted as being "easier to digest and understand". Even the book's index is surprisingly extensive and comprehensive, and misses very few important items. When the working examples actually are repackaged from Cisco's web content, the explanations and follow-throughs are incisive and accurate. Knowledge and understanding can be gained from every page without overkill or excessive repetition.
Any exam candidate seeking an in-depth review and preparation for the Cisco QOS or DQOS exams will find this book a treasure trove chocked full of the expected scenerios, examples and practice questions. All networking professionals should strongly consider stocking this in their personal reference collection for handy lookups to otherwise difficult QOS problems. However, I caution one, if you're seeking a quick and simple introduction to QOS, or looking to "break into" or "get their foot in the door" of internetworking, you should go elsewhere. This is definitely not the kiddy end of the pool. But then again, it certainly won't require the deep sea background of a CCIE either. This manual may start with the foundations of QOS but it very quickly ramps up to a professional-level internetworking reference. This is a book that goes beyond the classroom and heads straight for the real world.
As my industry and workplace move further towards voice and data "Convergence", this book has quickly become my working cookbook for smoothing out tough QOS implementation questions. And, It shall remain an important part of my desktop reference library for a long time to come.
