摘      要：Optical networks act as a backbone for coming generation high speed *** applications demand a very high bandwidth which can be exploited with the use of wavelength division multiplexing(WDM)*** issue of setting light paths for the traffic demands is routing and wavelength assignment(RWA)*** on the type of traffic patterns,it can be categorized as offline or online *** this paper,an effective solution to offline(static)routing and wavelength assignment is presented considering multiple objectives ***,the flower pollination(FP)technique is *** the problem is extended with the parallel hybrid technique with flower pollination and intelligent water drop algorithm(FPIWDA).Further,FPIWD is hybrid in parallel with simulated annealing(SA)algorithm to propose a parallel hybrid algorithm *** results obtained through extensive simulation show the superiority of FPIWD as compared to ***,the results in terms of blocking probability with respect to wavelengths and load of FPIWDSA are more propitious than FP and FPIWD.
