Abstract

Elastic optical networks (EONs) have been target of recent studies because of their ability to transmit data with different bandwidths, adapted to the demand. As a promising approach to implement optical network, techniques and heuristics have been presented for EON in order to explore their benefits and find solutions for their problems, including the Routing and Spectrum Assignment problem. In this work we propose the utilization of the Split Spectrum (SS) technique applied in the routing process, combined with the spectrum assignment algorithm named Min Slot-Continuity Capacity Loss (MSCL). It is shown that by combining different forms of spectrum division with the spectrum assignment that generates the least capacity loss, we can find an efficient technique that may be applied to EONs and provides better results than traditional spectrum assignment and the classic form of spectrum division.
