Benefiting from the development of 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. In this paper, the Survivable Routing, Baud rate, FEC Coding, Modulation Level, and Spectrum Allocation problem (Survivable RBCMLSA) on Elastic Optical Network (EON) is defined and studied. The Dedicated Path Protection (DPP) and Shared Backup Path Protection (SBPP) schemes are considered in this article. Several survivable routing algorithms are proposed to solve this problem. The proposed algorithms are examined through simulations and the results show that the proposed algorithms can achieve good results.
