摘要： Systems and methods for routing wavelengths in an optical network include responsive to a path request for a wavelength or group of wavelengths, determining a path through the optical network; determining a location on the path where wavelength blocking should occur to form a loop-free path in the optical network; and setting the wavelength blocking at the location. The optical network can utilize a broadcast and select architecture and the wavelength blocking is configured to prevent the wavelength or group of wavelengths from looping back on a port where the wavelength or group of wavelengths has already been received on. The optical network can utilize an all-broadcast architecture and the wavelength blocking is configured to prevent multiple paths for the wavelength or group of wavelengths by constraining the wavelength or group of wavelengths to a single path through the optical network.
