Abstract:
This work extends for translucent optical networks the solution to the problem of finding the best choice among M combinations of the shortest paths. The proposed Best Shortest Translucent Lightpath (BSTL) is a novel optical routing strategy, adaptive and aware of the optical physical layer impairments. The performance of BSTL is evaluated at different scenarios (topologies, regenerator placements, impairment thresholds, etc.) using metrics like network utilization, blocking probability, and fairness. In all these scenarios, BSTL achieved a better performance that related algorithms, such as PIARA.
