SYSTEM AND METHOD FOR WAVELENGTH CONVERSION AND SWITCHING

摘要

A network component comprising at least one processor configured to implement a method comprising collecting wavelength availability information associated with a wavelength switched optical network (WSON), receiving a path computation request to transport a signal through the WSON, calculating at least one route through the WSON for the signal, and assigning at least one wavelength for the signal to use along the route. Also disclosed is a network comprising a first path computation element (PCE) configured to compute at least one route for a signal between a source and a destination, and a second PCE in communication with the first PCE, wherein the second PCE is configured to receive the route from the first PCE and assign at least one wavelength to the route.
