Abstract

【Objective】

To address fault localization in high-dimensional optical switching networks—achieving precise identification of failures at the optical-device level both inside switching nodes and along communication links

and thereby providing effective technical support for the operation and maintenance of intelligent optical networks—this paper proposes a failure localization algorithm based on a Cascaded Neural Network (Ca-NN) model.

【Methods】

The paper analyzes the network architecture and its networking characteristics

designs a model backtracking strategy to address failure localization errors

and introduces the ant colony algorithm to achieve efficient deployment of the Optical Performance Monitor (OPM). Finally

numerical evaluations are conducted on a network topology consisting of 5 nodes and 8 bidirectional links.

【Results】

The simulation results demonstrate that the proposed algorithm achieves higher failure localization accuracy compared to traditional algorithms under various optical component types and different deployment ratios of OPMs.

【Conclusion】

The proposed algorithm is specifically designed to address the failure localization problem in high-degree optical switching networks

featuring high localization accuracy and effective error correction capabilities. The developed algorithm provides effective technical support for the operation and maintenance of large-capacity and highly reliable optical networks.
