Strategies for the Routing and Wavelength Assignment of Scheduled and Random Lightpath Demands

Abstract. We propose three routing strategies for the routing and wavelength assignment (RWA) of scheduled and random lightpath demands in a wavelength-switching mesh network without wavelength conversion functionality. Scheduled lightpath demands (SLDs) are connection demands for which the set-up and tear-down times are known in advance as opposed to random lightpath demands (RLDs) which are dynamically established and released in response to a random pattern of requests. The routing strategies are studied and compared through rejection ratio.
