Rating: Summary: False advertising Review: Although the book does have some good content, I bought the book specifically based on the front cover claim that it included free MP3 audio files of the book.Well it doesnt. I have registered the book on Syngress.com, downloaded the ebook and sent messages to the author and syngress. As yet still no mp3 files or even replies to my messages. The book may well be worth buying, but dont base your decision on the claims on the front cover.
Rating: Summary: ERRORS- Too Bad Review: Sorry to say there are errors in this book. I will point out the section on CAR (Committed Access Rate) on pages 188-196. For example on page 189 in his initial example. His objective is to assign web traffic an IP Precedence of 5 up to a bandwidth of 4 MB. Anything over 4MB rate is to be assigned to a best effort delivery class (an IP Precedence of 0). His solution is: rate-limit input access-group 101 16000000 4000 4000 conform-action set prec-transmit 5 exceed action set-prec-transmit 0 My Solution: First of all his objective was to set the base rate to 4 MB. So instead of the value of 16000000 the value should be 4000000. If you leave the value to 16000000 16MB will pass through the interface "conformed" meaning it will mark all packets with an IP Precedence of 5. So much for best class delivery after 4MB. I'm not going to get technical but I just wanted to point out an example. This is just to point out something that set me back about one day on studying for my CCIE. I would not want someone else to rip their hair out on this because all of his examples on CAR is messed up. Went to B&N and looked at all the QOS books. Srinivas Vegesna's book was the book that helped me out the most. Yes his book may be a little into the math but at least it was correct with the info and the math will actually help you understand how the algorithm works if you need to go in-depth. Donald Lee's book is also great too but a little less intense on the math. Donald's book presents stuff in a easy to understand manner. Anyway this book is rated 5 stars and supposedly is best seller. Nobody reported errors and there is no errata posted on the web site. All I can say is why. So I post only to inform.
Rating: Summary: Excellent Content Review: This book contains excellent content for those interested in implementing QoS over their IP network(s). The topics on congestion avoidance and congestion management were especially useful. I would suggest this book to any engineer attempting to deploy QoS on their network.
