Aiming at the uncertainty problem of crosstalk attack detection and attack source localization in multi-domain optical networks, a new crosstalk attack detection and location method in multi-domain optical networks is proposed by using distributed PCE architecture and monitoring point placement strategy based on grey theory. Meanwhile, an example is given. The experimental results show that the proposed method is effective.
