Not only summarizes the fundamental mechanisms and the development and deployment of optical WDM networks but also the details of both the network and software architecture needed to implement WDM enabled optical networks designed to transport IP traffic. Next-generation networks using IP over optical networks quickly emerged not only in the backbone but also in metro and access networks. So integrating IP and WDM to transport IP traffic over WDM enabled optical networks efficiently and effectively is an urgent yet important task. Presents all requirements for WDM optical network (enabling technologies, optical components, software architecture, management, etc.). Technical engineers and network practitioners, designers and analysts, network managers and technical staff as well as first-year graduate student or senior student majoring in networking and / or network control and management will all find this indispensable.
