This paper proposes a new Routing, Modulation Level and Spectrum Assignment (RMLSA) algorithm that considers the effects of physical layer in transparent elastic optical networks. The goal of the algorithm is to reduce the circuit blocking probability caused by the transmission quality degradation in the establishment of new circuits. The proposed algorithm is compared with two other Impairment-Aware RMLSA (IA-RMLSA) algorithms: Modified Dijkstra Path Computation (MD-PC) and K-Shortest Path Computation (KS-PC). The IA-RMLSA algorithms are evaluated under three different composition of bandwidth request for EON and NSFNet network topologies. Besides, we also evaluated the performance of IA-RMLSA algorithms using First-Fit and Best-Fit to spectrum assignment.
