Abstract


The thesis is mainly research the RWA(Routing Wavelength Assignment)of WDM(Wavelength Division Multiplex) in dynamic service . After analyzing the existent wavelength assignment algorithms, I find most of the new algorithms are focus on reducing BLC(Bottle Link Capability) but they neglect the connection between BLC and wavelength. On the base of compositive analysis of BLC and wavelength, I bring forward a new wavelength assignment algorithm: SE(Service Equalization).The algorithm is focus on equally sharing the service on each link ,so we can reduce blocking probability .I prove my ideas through computing simulation. Through the simulation on the CERNET in three different condition(each link can hold 4、8 or 16 wavelength),we could make a conclusion that the larger the wavelength is ,the better the SE algorithm is than the FF algorithm in the blocking probability.
