Recently,with the development of the Internet of Things and Cloud Computing,the optical Wavelength Division Multiplexing( WDM) network becomes more and more important.Virtualization Network( VN) and Routing Wavelength Assignment( RWA) are the key technologies of WDMoptical network. However,the superior performance of the VN mapping and RWA,which contains many constraints,is a NP hard problem to the target solving.Therefore,in order to simplify the problem,more research is just based on the subproblem of VN ...
