"For that reason, this book will be very useful for
undergraduate students and practitioners who need a good
introduction to, or a refresher on, the reliability aspects of the
networks they work with." (Computing Reviews, 14
January 2013)

"This well-organized book compares and contrasts the
reliabilities of corresponding components that make up
today's major networks as well as the reliability of
facilities used to operate them." (Optics &
Photonics News, 1 November 2013)
