【Abstract】 Dynamic routing and wavelength assignment in the WDM networks with both dynamic service traffic and limited range wavelength conversion has been discussed. According to probability and limitation of wavelength conversion, a novel initiatory algorithm, which could achieve dynamic minimum cost routing and optimal virtual wavelength path, DMC OVWP, was proposed based on Moone Dijkstra algorithm. With sepa ration and combination of routing subproblem and wavelength assignment subproblem, the algorithm optimizes RWA problem and so guarantees information transmission security in WDM optical network. The results simulating CERNET using the algorithm shows that low blocking probablity has been obtained.更多还原
