Abstract
Methods and systems are disclosed including receiving, by circuitry of a node conforming to GMPLS protocol, a signal comprising at least one of an optical signal attribute indicative of parameters of a super-channel, the super-channel including a plurality of optical carriers, each of which having a corresponding one of a plurality of wavelengths and being modulated to carry a corresponding one of a plurality of data streams, the super-channel being provisioned in the optical network as one optical channel, wherein the optical signal attribute is one of: quantity of wavelengths of the super-channel, wavelength center frequency of the super-channel, wavelength modulation of the super-channel, wavelength baudrate of the super-channel, and wavelength FEC type of the super-channel. The node further receiving information indicative of frequency slices in use by the super-channel and calculating, using algorithms conforming to CSPF-TE protocol, a path of a second super-channel.
