ASSIGNMENT OF WAVELENGTHS TO OPTICAL SIGNALS IN AN OPTICAL NETWORK

摘要

A method may include determining, by a device, a wavelength identifier graph corresponding to an optical network based on a set of lightpath conflicts, for a set of optical signals, associated with a set of links and a set of nodes of the optical network. One or more optical signals may be associated with transmission via a super-channel. The method may further include selectively assigning, by the device, a wavelength identifier to an optical signal, of the set of optical signals, based on the wavelength identifier graph. The wavelength identifier being associated with a set of wavelength identifiers and corresponding to a wavelength of a set of wavelengths. The method may further include causing, by the device, the optical signal to utilize the wavelength, of the set of wavelengths, for transmission via the optical network.
