Optical Network Control: Architecture, Protocols, and Standards

Preface

Optical networks were initially designed and deployed to provide high-capacity transport for carrying telephone calls. Today they are used to transport not only voice traffic, but also data traffic, including Internet traffic. In fact, it is the Internet that has driven the rapid and unprecedented growth of optical networks in the past several years. New technologies, such as Dense Wavelength Division Multiplexing (DWDM) and intelligent optical switches, have been the other catalysts of growth. Although this rapid growth of optical networks has ushered in a new era in high-speed communication, it has also created a new problem. Managing a large and dynamic optical network is a difficult task, and the existing network management infrastructure ...
