Abstract

As a key problem in wavelength switched optical networks (WSON) in which wavelengths are the most important resources, routing and wavelength assignment (RWA) problem has been researched extensively. Due to the advantages of path computation in multi-layer and multi-domain networks, especially in multi-constraints scenarios, path computation element (PCE) has been introduced into WSON, which provides a better approach to the solution of RWA problem in WSON. A novel PCE-based wavelength assignment scheme CRWA-PQ is proposed in wavelength switched optical networks (WSON), and compared with several other schemes by simulation using OMNeT++.
