PATH COMPUTATION ELEMENT PROTOCOL (PCEP) OPERATIONS TO SUPPORT WAVELENGTH SWITCHED OPTICAL NETWORK ROUTING, WAVELENGTH ASSIGNMENT, AND IMPAIRMENT VALIDATION |
摘要 |
<p>An apparatus comprising a path computation element (PCE) configured for at least partial impairment aware routing and wavelength assignment (RWA) and to communicate with a path computation client (PCC) based on a PCE protocol (PCEP) that supports path routing, wavelength assignment (WA), and impairment validation (IV). The PCEP comprises at least one operation selected from the group consisting of a new RWA path request operation and a path re-optimization request operation. Also disclosed is a network component comprising at least one processor configured to implement a method comprising establishing a PCEP session with a PCC, receiving path computation information comprising RWA information and constraints from the PCC, and establishing impairment aware RWA (IA-RWA) based on the path computation information and a private impairment information for a vendor's equipment.</p> |
