Dense wavelength division multiplexing (DWDM) optical networks are prone to failure, which can potentially lead to a catastrophic loss of data and revenue. Given this, one of the most important optical network design issues is survivability or the ability of a network to provide continuous service at an acceptable level in the presence of different failure scenarios. Resilient Optical Network Design: Advances in Fault-Tolerant Methodologies is a collection of the latest contributions to the area of survivability in optical networks. Each chapter focuses on theoretical and practical aspects of network survivability methodologies applied to real world scenarios, making this a useful reference for research and development engineers, graduate students studying optical networks, and senior undergraduate students with a background in algorithms and networking.
