High-Power Jamming Attack Mitigation Techniques in Spectrally-Spatially Flexible Optical Networks

This work presents efficient connection provisioning techniques mitigating high-power jamming attacks in spectrally-spatially flexible optical networks (SS-FONs) utilizing multicore fibers. High-power are modeled based on their impact the lightpaths’ quality of transmission (QoT) through inter-core crosstalk. Based a desired threshold lightpath’s QoT, modulation format used, length path, as well set physical layer characteristics, each lightpath can potentially tolerate attack. In this paper, an integer linear program is thus formulated, heuristic algorithms to solve problem attack-aware routing, spectrum, format, and core allocation SS-FONs, aiming both efficiently provision network terms resources, minimize established lightpaths. Extensive simulation results obtained for several algorithm variants with different objectives, demonstrating validity efficiency proposed that effectively mitigate attacks, by minimizing number interactions, while at same time establishing connections high spectral efficiency.
