Abstract
An apparatus comprising a path computation element (PCE) coupled to a path computation client (PCC) and configured to perform a path computation using port wavelength restriction information for a network element (NE), wherein the port wavelength restriction information is encoded and received in a port wavelength restriction Type-Length-Value (TLV) that comprises a matrix identifier (ID), a restriction type, and the port wavelength restriction information. Also disclosed is a network component comprising at least one processor coupled to a memory and configured to receive a port wavelength restriction information TLV that corresponds to a NE, and obtain a restriction type and port wavelength restriction information based on the restriction type from the port wavelength restriction TLV, and use the port wavelength restriction information to calculate a path for the NE.
