Otn digital twin network generation method and system based on longitudinal federated learning

Abstract

In the present disclosure a method and a system for generating an Optical Transport Network (OTN) DT network based on vertical federated learning are disclosed. The method includes: performing homomorphic encryption on a local fault root cause identifier to obtain an encrypted fault root cause identifier; receiving all encrypted alarm sample sequences corresponding to the encrypted fault root cause identifier; generating a single-domain training set according to the encrypted fault root cause identifier and the encrypted alarm sample sequences; training the local cross-domain fault root cause identification model according to the single-domain training set to obtain a model parameter update amount of the cross-domain fault root cause identification model; and reporting the model parameter update amount to the multi-domain orchestration system.
