Abstract:
Benefiting from the development of coherent detection and digital signal processing, innovative optical transceivers enable the dynamic adaptation of the baud rate, modulation level and Forward Error Correction (FEC) coding to the optical transmission properties. Next generation optical networks will require high levels of flexibility, being able to fit rate, bandwidth, FEC coding and optical reach requirements of different connections. For serving transmission on an Elastic Optical Network (EON), the flexible lightpath routing and the spectrum allocated for the connection request should be developed to meet the traffic requirement. In this paper, the Routing, Baud rate, FEC Coding, Modulation Level, Spectrum Allocation (RBCMLSA) problem is defined and studied. A heuristic algorithm, which integrates single/multiple path routing schemes, is proposed. The proposed algorithm is examined through simulations and the results show that the proposed algorithms can achieve good results.
