Abstract: Deliberate malicious attacks performed by high-power jamming signals can put large amount of data under risk. We investigate the problem of survivable optical networks resource allocation scheme against malicious attacks. We consider wavelength-division multiplexing (WDM) networks, two types of attacks: in-band and out-of-band attacks, and dynamic traffic. The proposed approaches were able to limit the vulnerability of lightpaths to jamming attacks. Recently, natural disasters and/or deliberate attacks has left major parts of data center networks (DCNs) damaged or disconnected. We also investigate the problem of disaster-aware resource provisioning in case of disasters for DCNs and using path-protection under dynamic traffic. Our models show significant resource savings while accommodating users demands. Optical networks using space division multiplexing (SDM) has been proposed as a solution to the speed bottleneck anticipated in DCNs. To the best of our knowledge, the new challenges of designing such communication systems have not been addressed yet. We propose an optimal approach to the problem of developing path-protection scheme to handle communication requests in DCNs using elastic optical networking and SDM.  Our simulations explore important features of our approach.
