| Descripció: | Physical layer impairments accumulate as light propagates through a lightpath in the transparent optical networks. Therefore, it is possible to provision a lightpath, while its quality of transmission (QoT) does not meet the required threshold. Considering
the physical layer impairments in the network planning phase gives rise to a set of offline Impairments Aware Routing and
Wavelength Assignment (IA-RWA) algorithms. There are very few offline IA-RWA algorithms that consider dedicated path protection demands. In this work we propose a novel offline IA-RWA algorithm, called Rahyab and perform a comparative performance evaluation study, which considers two enhanced algorithms from the literature. Simulation results indicates that demand pre-processing,
diverse routing, and adaptive wavelength assignment are the main reasons of lower blocking rate of Rahyab algorithm compared
to the selected algorithms. |
