Propagation Effect Of High-powered Intra-channel And Inter-channel Crosstalk Attack In All-Optical Networks

With the development of network information, more and more Internet application has been popular to public users, such as cloud computing, IPTV, etc., which requires higher network bandwidths. However, in WDM optical network, the "electronic bottleneck" within intermediate nodes seriously limites the network delivery rates. So AON has been proposed and attracts more and more attention. However, transparency will also induce high-powered all-optical attack threats to AON. There are three main all-optical attack, including intra-, inter-channel crosstalk and gain competition attack. In this paper, we concentrate on the propagation effect of high-powered intra-and inter-channel crosstalk attack in AON.In this paper, the attack scenarios of both intra-and inter-channel crosstalk are proposed by comparing the propagation effects of the attack with the networks. Via VPI simulation platform, we implement fiber communication systems containing the attack scenarios. By analyzing the physical impairments of legitimate signals, we verify the existence of the attack scenarios and the quantified propagation results are presented.During the simulation, we find a new attack approach, named indirect inter-channel crosstalk attack, and via VPI, we verify the existence of such attack and present the quantified propagation effects.Based on the previous physical impairment results, a new all-optical attack model is proposed, including intra-, inter-channel crosstalk and gain competition attack. We apply the model to attack-aware RWA algorithms and run it on NSF simulation network. The results indicate that the less block probabilities can be achieved via the model and it can also reduce the attack effects induced by high-powered all-optical attack.In this paper, the propagation effect of high-powered intra-and inter-channel crosstalk attack is investigated via VPI simulation platform. Based on the quantified simulation results, a new all-optical attack model is proposed. The results are useful to future relative researches on high-powered all-optical attack and attack-aware resource scheduling in AON. Additionally, the results can also lead to more scientific researches on attack monitoring, localization and protection engineering.
