This book takes a pragmatic approach to deploying state-of-the-art
optical networking equipment in metro-core and backbone networks. The
book is oriented towards practical implementation of optical network
design. Algorithms and methodologies related to routing, regeneration,
wavelength assignment, sub rate-traffic grooming and protection are
presented, with an emphasis on optical-bypass-enabled (or all-optical)
networks. The author has emphasized the economics of optical networking,
with a full chapter of economic studies that offer guidelines as to when
and how optical-bypass technology should be deployed. This new edition
contains: new chapter on dynamic optical networking and a new chapter on
flexible/elastic optical networks. Expanded coverage of new
physical-layer technology (e.g., coherent detection) and its impact on
network design and enhanced coverage of ROADM architectures and
properties, including colorless, directionless, contentionless and
gridless. Covers 'hot' topics, such as Software Defined Networking and
energy efficiency, algorithmic advancements and techniques, especially
in the area of impairment-aware routing and wavelength assignment.
Provides more illustrative examples of concepts are provided, using
three reference networks (the topology files for the networks are
provided on a web site, for further studies by the reader). Also
exercises have been added at the end of the chapters to enhance the
book's utility as a course textbook.
