Wavelength assignment for reducing in-band crosstalk attack propagation in optical networks: ILP formulations and heuristic algorithms

Today’s Transparent Optical Networks (TONs) are highly vulnerable to various physical-layer attacks, such as high-power jamming, which can cause severe service disruption or even service denial. The transparency of TONs enables certain attacks to propagate through the network, not only increasing their damage proportions, but also making source identification and attack localization more difficult. High-power jamming attacks causing in-band crosstalk in switches are amongst the most malicious of such attacks. In this paper, we propose a wavelength assignment scheme to reduce their damage assuming limited attack propagation capabilities. This complements our previous work in Furdek et al. (M. Furdek, N. Skorin-Kapov, M. Grbac, Attack-aware wavelength assignment for localization of in-band crosstalk attack propagation, IEEE/OSA Journal of Optical Communications and Networking 2 (11) (2010) 1000–1009) where we investigated infinite jamming attack propagation to find an upper bound on the network vulnerability to such attacks. Here, we consider a more realistic scenario where crosstalk attacks can spread only via primary and/or secondary attackers and define new objective criteria for wavelength assignment, called the PAR (Primary Attack Radius) and SAR (Secondary Attack Radius), accordingly. We formulate the problem variants as integer linear programs (ILPs) with the objectives of minimizing the PAR and SAR values. Due to the intractability of the ILP formulations, for larger instances we propose GRASP (Greedy Randomized Adaptive Search Procedure) heuristic algorithms to find suboptimal solutions in reasonable time. Results show that these approaches can obtain solutions using the same number of wavelengths as classical wavelength assignment, while significantly reducing jamming attack damage proportions in optical networks.

Special issue based on selected IEEE ONDM 2015 papers

The 19th International Conference on Optical Networks Design and Modeling—IEEE ONDM 2015 (http://ondm2015. sssup.it/)—was held in Pisa, Italy, on May 11–14, 2015. IEEE ONDM is one of the premier venues in Europe for the optical network community to meet and exchange ideas. Along with the tradition of previous editions of this conference, ONDM 2015 addressed cutting-edge research in established areas such as optical networking, optical systems, as well as emerging topics like novel Internet architectures, new optical network architectures for the Cloud/DataCenter, wireless optical networks and photonic integrated networks. ONDM 2015 was a 3 full-day event organized by Scuola Superiore Sant’Anna (SSSA), and Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT). The event includes three keynote lectures, nine invited papers, regular papers and a workshop organized by the PACE project. ONDM 2015 was technically co-sponsored by the IFIP TC 6 (working group 6.10), by IEEE and by the IEEE Communication Society with the endorsement of the TAOS and ONTC. The conference was also supported by Ericsson, Nextworks, Interoute and FP7 PACE project. More than 80 high quality technical papers were submitted by researchers from 29 countries all over the world. All submitted papers were peer reviewed by the Members of the
