A multi-point crosstalk attack detection and localization scheme based on hierarchical PCE in multi-domain optical networks

Abstract

With the limited number of detection devices and the uncertainty of crosstalk attack source localization, how to propose an effective detection and localization scheme for multipoint crosstalk attack problem in multi-domain optical networks is an important problem that needs to be solved. A new multipoint crosstalk attack detection and location scheme HP-CADL (Hierarchical PCE-Crosstalk Attack Detection and Location) for multi-domain optical networks based on hierarchical PCE is proposed by using the monitoring point selection strategy of local immune algorithm and distributed localization considering continuous parametric analysis. VPI simulation results show that the scheme not only achieves low-cost monitoring and detection and accurate localization of multiple crosstalk attack sources, but also achieves higher accuracy and better performance than other similar schemes in the same multi-domain environment.
