We propose and evaluate a Greedy Randomized Adaptive Search Procedure applied to minimize the number of power equalizers (GRASP-PE) needed to limit the propagation of high-power jamming attacks in WDM networks. Simulation results show that GRASP-PE significantly reduces the required number of power equalizers when compared to a greedy approach. 1.(More)

Physical layer attacks in transparent optical networks are a serious security threat to network operation. We propose a novel protection approach based on wavelength assignment which limits the maximal propagation of intra-channel crosstalk attacks. 1. Introduction In Transparent Optical Networks (TONs), all-optical data connections, called lightpaths, are(More)
