In wavelength routed WDM networks, a connection is realized by a lightpath. In order to establish a connection between a source-destination pair, a wavelength continuous route needs to be found between a node pair. An algorithm used for selecting routes and wavelengths to establish lightpaths is known as a routing and wavelength Assignment (RWA) algorithm. Therefore, it is mandatory to use a good routing and wavelength assignment algorithm to establish lightpaths in an efficient manner.
1. What is WDM networking?
2. What is RWA protocol?
3. What is use of double CMS RWA protocol?
