Title: Lots of errors, not useful for engineers
Product review: The claim of this book is to present "next generation" networks, however out of the 198 pages only 20 pages cover the enablers for these networks: LCAS and GFP. And even these sections are full of technological errors and are incomplete. Other sections in the book contain also many technological errors. This book contains more errors than his previous book "Understanding SONET/SDH and ATM". I get the strong impression that the author copy/pasted parts of the many references (20 pages!) without having the knowledge of the technology he tries to describe.A better book to read is: "Next generation SDH/SONET: Evolution or Revolution?" as this focusses completely on LCAS and GFP.
