"If one desires to learn as extensive and still evolving a field as network recovery, he or she will be interested in a book prepared by authors related to two somewhat separate worlds: industry and academia. ... This combination of knowledge gives an excellent overview of hot topics related to communications network resilience.... The advantage of this book is related to the fact that each chapter can be read separately, since the authors briefly repeat the most important ideas as necessary. The other benefit is that the current state of the development level of some techniques is signaled. To sum up, the book gives the reader a deep insight into "how it works." ... Thanks to this fact, the book can be recommended to everybody interested in network recovery, from layperson to experienced designer who would like to learn about the latest solutions." -- IEEE Communications Magazine, Book Reviews, July 2005. Reviewer: Piotr Cholda

"This is the right book at the right time for anyone in the telecommunications business, or anyone who is dependent on the services provided by the telecommunications business that would like to understand the new Internet that is rapidly becoming the common reality."
-From the Foreword by Scott Bradner, Senior Technical Consultant and University Technology, Security Officer at Harvard University

"This book provides a welcome overview of the many techniques applied to protect and recover data paths in IP and MPLS networks as well as in SONET/SDH and optical transport networks. The analysis and case studies of MPLS Traffic Engineering recovery mechanisms will be particularly useful to operators intending to deploy MPLS protection within their networks."
-Adrian Farrel, Old Dog Consulting & Co-Chair of the IETF CCAMP Working Group

"I recommend this book to anyone responsible for the design, implementation and management of any-sized communications network."
-David Cooper, Global Crossing

"Writing a didactic and up-to-date book on protection and restoration techniques in new generation WDM networks is a real challenge. This requires two distinct fields of expertise in new generation IP/MPLS networks and in advanced optical transmission systems respectively. For the first time, such specialists have joined their efforts to make a book that gives readers a unique opportunity for understanding the details behind the main characteristics and challenges of multi-layer survivability."
-Maurice Gagnaire, ENST, École Nationale Supérieure des Télécommunications
