Survivable Routing in Spectrally-Spatially Flexible Optical Networks with Back-to-Back Regeneration

In this article, we address the problem of survivable routing in spectrally-spatially flexible optical networks (SS-FONs) with dedicated path protection (DPP). The considered SS-FON supports spectral super-channel transmissions, in which flexible signal regeneration is realized with transceivers operating in back-to-back (B2B) configurations. We propose an Adaptive Survivable Routing with Back-to-Back Regeneration (ASRBR) algorithm to realize...
