Suspect Fault Screening Assisted Graph Aggregation Network for Intra-/Inter-Node Failure Localization in ROADM-based Optical Networks

We propose a suspect fault screening assisted graph aggregation network for intra-/inter-node failure localization in ROADM-based optical networks, which is validated in both simulated topology and testbed. Results show that it achieves satisfactory accuracy under different percentage of OPMs and the number of service requests.
