  • PCEP extension to support flexi-grid optical networks
    Patent number: 10530631
    Abstract: A computer-implemented method of requesting a path on a flexi-grid network comprises: sending, by a path computation client (PCC), a request for a path to a path computation element (PCE), the request including the request including: a label that identifies spectrum to be restricted from use in the path; and a channel spacing field; and receiving, by the PCC and from the PCE, a response to the request, the response including an identifier of an assigned path on the flexi-grid network.
