I do not recommend this book for any one who needs to troubleshoot Frame Relay. It covers general Frame Relay concepts fairly well, but seriously lacks detail. After reading another FR book I discovered how much detail this book is missing.

Unfortunately the mistakes in the book are there. See above reviews for mathematical mistakes. I confirm that these mistakes are there.

Please nore that my review of Frame Relay Networks : Specifications and Implementations (Signature) by Uyless D. Black should be given at most 2*s

Reading the limited math in this book is very frustrating. The typographical errors and technical errors in this book are a disgrace. They cause the reader to waste considerable time in trying to correct the author's and publisher's errors. An example of technical error is the definition of "B sub c" and "B sub e" on page 162 as data rates rather than their correct characterization as burst sizes. Then on page 163 defining the Committed Information Rate(CIR) as CIR=Bsubc/Tsubc. A rate divided by time is not a rate! The correct characterization is given on page 204 of "Frame Relay Principles and Applications" by Philip Smith, Addison-Wesley.

Obvious typographical errors of mathematical expressions appear wherever an equation is provided in the text for example those on page 168 for the "Area of the previous cycle" and on 181 for the variable SRTT, smoothed round trip time.

The math in this book is not rocket science yet the author and the publisher can't get it correct! Such errors are inexcusable considering the price of this soft covered book.
