Abstract The success of the next generation optical networks relies on their ability to cope with different limitations imposed by the opticalphysical layer, such as the optical power control of the WDM channels, and the physical impairments caused by the fiber, the network elements and channel crosstalk.Indeed, in a transparent network, since there is no signal regeneration, noise and signal distortion accumulate along the lightpath, in such a way that there are routes that cannot be established, because they do not have an acceptable transmission performance.Therefore, in the routing and wavelength assignment (RWA) problem, in addition to the logical network aspect, it is necessary to take into consideration the physical layer impairments. Those algorithms that make these considerations are known as IA-RWA.Moreover, those IA-RWA algorithms must be incorporated into the control plane in order to allow for the distributed management of theoptical network.Thus, this project aims at the study and the development of novel IA-RWA algorithms, which are incorporated into the network control plane. | |
