Abstract: A data processing method where an analysis device obtains first network data and historical fault propagation paths and processes the first network data to obtain a first fault propagation path. When the historical fault propagation paths include a target fault propagation path that is the same as the first fault propagation path, the analysis device updates a quantity of target fault propagation paths.
