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.

Abstract: A node is configured to receive an instruction to establish a channel having a bandwidth that corresponds to an operating spectrum an optical fiber; obtain information that identifies a channel spacing and a pointer that identifies where, within the spectrum, to establish bandwidth allocations; identify a group of bandwidth segments based on the spectrum and the channel spacing; and generate bit words that correspond to the bandwidth allocations, where the bit words includes bits that, when set to a value, cause sets of segments to be reserved within the spectrum, and where the sets of segments identify where the bandwidth allocations begin and end, within the spectrum, relative to the pointer.

Abstract: An example method includes identifying a fault condition in a network, and evaluating pseudowires affected by the fault condition in order to make a determination as to whether an aggregate failure occurred in the network for a group of pseudowires. The method also includes communicating a group message indicating that the group of pseudowires is associated with the fault condition. The group message includes a group identification (ID), which identifies the group of pseudowires, and the group message includes a pseudowire group label identifying an in-band aggregate channel. More specifically, the pseudowire group label can be applicable to static pseudowires. In more detailed embodiments, the group ID identifies the group of pseudowires that are associated with an attachment circuit, a label switched path, or a port. Internal mappings can be maintained such that a plurality of pseudowires is mapped to individual interfaces of network elements in the network.
