This paper presents a novel optimized distributed dynamic wavelength assignment algorithm for the wavelength routing optical network(WRON) based on the revised result of reference[5,6]: Fast Distributed Dynamic Lightpath Setup Algorithm(FDDLSA). By adopting two kinds of new optical link release mechanisms (ahead and timeout release) in the process of networks nodes setting up a link, the new algorithm can reduce the blocking probability significantly and release the burden of a router. The effectiveness of the algorithms was verified through the simulation on NSF net (Nature and Science Founda...
