Systems and methods for routing and wavelength assignment for network virtualization
A method for routing and wavelength assignment for optical network resources required for a plurality of virtual network requests includes receiving the plurality of virtual network requests. The method further includes determining a number of virtual links for each virtual network request. The method includes sorting the plurality of virtual network requests based on the number of virtual links, and selecting a virtual network request from the plurality of virtual network requests and setting a number of allowable spans. Additionally, the method includes determining whether a valid virtual node mapping exists for the virtual network request on any of a plurality of wavelengths based on the allowable spans, and based on determining that no valid virtual node mapping exists on any of the plurality of wavelengths, incrementing the number of allowable spans.
