This paper studies a wavelength-convertible core optical network1 consisting of backbone nodes with optical switches interconnected by point-to-point WDM fiber links in a mesh interconnection pattern. The optical network supports unprotected and shared-mesh protected lightpath services. Lightpaths are routed from a centralized management system that has access to the network inventory, including the topology and light-path databases.
