Although IP and WDM technologies are expected to become the dominant network technologies, they will be introduced gradually to complement and replace ATM and SDH network solutions. This text reviews and researches results for the deployment and management of IP over WDM networks with guaranteed service level agreements. Design details cover the integrated management requirements and architectures needed to ensure direct and seamless deployment and integration of IP and WDM. Verification of the management and networking concepts has been performed on a research testbed built from WDM rings and IP routing equipment as part of the WINMAN project, which is a European Union-sponsored research project. The volume concludes with an outlook on the expected evolutions of network management and the deployment of optical networks.
