摘要：
The disclosure includes an apparatus comprising a path computation element (PCE) that manages the processes of routing in an optical network, wherein the PCE receives a path computation request and provides a wavelength range to a network element (NE), and wherein the NE assigns a wavelength from the wavelength range. Also disclosed is an apparatus comprising a path computation client (PCC) that sends a path computation request to a path computation client (PCE) using path computation element communication protocol (PCEP), and receives a routing and wavelength assignment (RWA) reply to the path computation request using PCEP, wherein the RWA reply comprises an PCEP error message comprising a PCEP error object and an error value to indicate errors associated with the RWA request.
