The book got the right balance between design and implementation.

Few important things I found missing in the book:
1. QOS on vlan interfaces and L3 interfaces on switches
2. QOS on router's ethernet interfaces which are used for WAN connection.
3. More detailes about how QOS impact CPU usage.

But most other things are well explained in the book.
A good read!

When this book first arrived at my doorstep, I figured it would be a quick read, a review of information I was already fairly comfortable with, and just another presentation of the same-old material. I couldn't have been more wrong! Over the last several months, a number of hours have been devoted to leafing through the pages of valuable information, learning something new every time! Szigeti and Hattingh have done a superb job in putting this reference together. From the basic fundamental concepts of QoS, to the tuning and optimization of QoS policies, this book covers it all pretty well. QoS design considerations, both on the campus as well as the WAN, are covered in a way that is easy to understand. A significant amount of material is dedicated to explaining QoS support on the various models of Cisco Catalyst switches, with a solid breakdown of each. A number of case studies guide you through real-world examples of how QoS technologies are best leveraged, in clear, concise detail. The at-a-glance guides in the back of the book are also good reference material. For the enterprise user and service provider alike, this guide will prove to be a valuable tool when tackling in the toughest of QoS tasks. I would give this book a solid 5 on the scale of 1 to 5, with 5 being amazing! Great job with this book, keep up the good work!

Welcome to Quality of Service (QoS). Life used to be so simple, you went to Ma Bell and ordered just what you wanted in switched or dedicated circuits and you got a (more or les) clear channel from Point A to Point B. But then we moved to packet switching where everything being sent is broken into small packets, given a destination address and thrown out into a big communications pipe with billions of other packets, each madly striving to get to its own destination.

This book starts with the early history of making some packets more equal than others (to borrow from George Orwell) so that time sensitive packets (like voice) have a priority over data for which a few tenths of a scond delay is not critical. It marches to the drumbeat that proper QoS structure in your network will provide satisfactory service to each user with the minimum outlay for bandwidth.

The book has enough background and basic information to be helpful to the user, and continues as far as you want to go into the details of individual pieces of equipment. Being as the book is from Cisco Press, obviously Cisco equipment is featured, but it is general enough to be of use with older legacy equipment and that of other manufacturers. It's the most complete book I've seen on the subject.

As the amount of information travelling through the wire in today's world
keeps increasing - voice and video kicking in - Quality of Service (QoS) has become a must in a network engineer arsenal.

Overlooked by many engineers, QoS has become a standard service in
every network and especially if you have Voice and Video services running.

While the automated QoS mechanisms found in Cisco equipment does
provide a level of prioritisation, the real power of QoS remains hidden
under the hood, until you decide to open it... which is where this book
comes into play.

"END - TO - END QOS NETWORK DESIGN" is the definite "Bible" for
someone seeking to get the expert advice for designing and implementing
QoS in a networking infrastructure no matter what the complexity might be.

This book explains in an excellent manner all the aspects of QoS
mechanisms, from the basic fundamental concepts of QoS, to the tuning
and optimization of QoS policies. It is also packed with very good examples and explanations on the different QoS technologies, both for LAN and WAN, helping the reader easily understand what "end-to-end QoS" actually means and how it is implemented.

As a final comment, don't underestimate "QoS At-a-Glance Summaries"
section. Cut if off and keep it close to you as a field manual.

This is the most complete book we've read on the subject here on
Firewall.cx, so 10++ for rating, which is the highest ever given score, is the least we can give to express our gratitude to the authors.
Don't look at the price tag - buy this book, and you'll quickly thank us for the advice!

It's a great book for a network engineer. I think it should be a must for any person who is looking to be a great network designer.

This book provides good coverage on the technical side. If you are also interested in the commercial/economic and regulatory side of QoS, then this book may be useful too:

The Broadband hype of converged networking, things like IPTV, VOIP, H.323, will never work without QoS. Now even the Microsoft Vista Kernel has QoS.

This is a great book about end-to-end QoS pratical examples, code, methods along with solid explanations of why and how. A must read for both LAN and WAN people. QoS is still diffcult but this book finally details practical standards that can be adhered too.

Excellent book. Well written and the material is very well presented. It covers the different QoS technologies with very good examples and explanations. This is a "must have" to any network engineer that is planning to design, deploy and maitain QoS in a networking infrastructure.

"Indispensable" is the one word which best describes this work. (In the interest of full disclosure, I've known Christina Hattingh for several years. As I've written in the acknowledgements of my books she is "one of the finest engineers I've known and worked with." I've never met Tim Szigeti.)

The authors have put together an outstanding work which incorporates real world experience, lucid explanations (see the section on 'qos pre-classify' on p.649, for example), and a wealth of configuration examples, show and debug command outputs.

If you need to "do" QoS, especially in a converged network, the contents of this book will be invaluable.
