The complete, example-based guide to advanced WDM networks.
Wavelength division multiplexing (WDM) and wavelength routing are rapidly becoming the technologies of choice in network infrastructure that must accommodate unprecedented, accelerating demand for bandwidth. WDM Optical Networks: Concepts, Design, and Algorithms provides practicing engineers, students, and researchers with a systematic, up-to-date introduction to the fundamental concepts, challenges, and state-of-the-art developments in WDM optical networks. The authors rely extensively on real-world examples and draw on the latest research to cover optical network design and provisioning in far greater depth than any other book. Coverage includes:
Focusing primarily on WDM technology, WDM Optical Networks will be invaluable to every network engineer, technical manager, researcher, and student involved with the design or implementation of advanced WDM networks.
(NOTE: Each chapter begins with an Introduction and concludes with Problems.)

Wavelength division multiplexing (WDM)transmitting manylight beams of different wavelengths simultaneously through an opticalfiberand wavelength routinga network switching (routing) node that routessignals based on their wavelengths-are rapidly becoming a technology-of-choice to meet the tremendous bandwidth demand of the new millennium. A WDM optical network consists of wavelength routing nodesinterconnected by point-to-point optical fiber links in an arbitrarytopology.Several important advantages, such as increased usable bandwidth on an optical fiber, reduced electronic processing cost, protocol transparency, and efficient network component (link/node)failure handling, have madewavelength routed WDM optical networks a de-facto standard for high-speed backbone transport networks.For the same reasons, they are receiving increasing attention from the telecommunications industry, network operators, and research communities all over the world. The purpose of this book is to provide students, researchers, and practicing engineers with an expert guide to the fundamental concepts, issues, and state-of-the-art developments in wavelength routed WDM optical networks. A unique approach of the book is that it provides easy-to-understand examples to illustrate the issues and solutions.
The book is organized into nine chapters, each covering a unique topic in detail. Unlike other books in this area, this book covers several important topics in wavelength routed WDM optical networks such as distributed routing protocols, provisioning multifiber networks,design of survivable networks, virtual topology reconfiguration, opticalmulticast routing, and next-generation optical Internets. The material covered in the book is up to date and is essentially derived from recently published research papers/results.Sufficient illustrative examples are provided in each chapter to allow better understanding of the concepts, issues addressed, and solutions to the issues, highlighting the intuition behind each of the solutions.Appendix A at the end of the book gives a Web resource list, with links to the home pages of several WDM optical component/system vendors.
The book is a useful resource for students and researchers to learn allabout WDM optical networks and further their research work. It is intended as a textbook for a senior undergraduate andgraduate-level course on optical networks or high-speed networks.It can also be used as a supplementary text for an undergraduate courseon computer networks. The exercise problems at the end of eachchapter add strength to the book. In addition, the book will be valuableto professionals in the field of computer networking.
