Abstract :
A routing solution is presented to find optimal routes for lightpaths and for the new concept of semi-lightpaths. A lightpath is a fully optical transmission path, while a semi-lightpath is a transmission path constructed by chaining together several lightpaths, using wavelength conversion at their junctions. A fast and practical algorithm, with proven optimal speed, is presented to optimally route lightpaths and semi-lightpaths taking into account both the cost of using the wavelengths on links and the cost of wavelength conversion
