The main aim of (RWA) is to maximize the number of established connections. The <br>significant indication by applying the RWA is to diminish the resources of the network demanded to serve <br>the same number of requests. Consequently, the total number of requests served by the same resources <br>will be increased. The main aim of this research is to manage the RWA algorithm by inspecting the <br>performance of each algorithm in static (Fixed Routing Algorithm and Fixed Alternate Routing Algorithm) <br>and dynamic routing algorithms in an optical network. With this work, the comparison between various <br>RWA algorithms is performed using sorted shortest path algorithm and non-sorted random algorithm. <br>Extra investigation and comparison can be achieved via the hiring Genetic algorithm (GA) as a tool to <br>enhance optical network performance. The proposed techniques are applied to the design of some <br>topologies depending on the number of nodes and the set of connecting links. With this work, it is assumed <br>that all nodes are with no wavelength conversion and the identical load was utilized on the network by <br>using three different algorithms. The comparison between the three algorithms shows that the dynamic <br>algorithm gives good throughput and less resource usage. Besides, it has been shown that the shortest path <br>algorithm yields results better than a random path algorithm. Finally, by using the GA tool in the <br>optimization, the results have been obtained within the accepted rate.</p>}, number={2}, journal={Journal of Duhok University}, author={SAEED, MOHAMMED GHANIM and MUSTAFA, FIRAS MAHMOOD}, year={2021}, month={Jan.}, pages={478-489} }
