Abstract: This application provides an optical link fault identification method, and relate to the field of communications technologies. The method includes: obtaining performance data of a network device, extracting a feature parameter of the performance data, and identifying a fault mode on an optical link based on the feature parameter. The method resolves problems of a difficulty in fault identification and slow troubleshooting that are caused by a large quantity of devices, many line faults, and a difficulty in obtaining manual troubleshooting cases. In addition, a fault can be quickly identified when the fault occurs, improving troubleshooting efficiency. When an optical link risk does not cause a fault, deterioration of the performance data can be found in advance based on a feature, to perform identification and warning.

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.

Abstract: This application discloses a fault recovery plan determining method, apparatus, and system, and a computer storage medium, and belongs to the field of network technologies. First, a control device obtains a similar known fault that is in a plurality of known faults and whose fault root cause and a fault root cause of a target fault in a network meet a similarity condition. Then, the control device obtains a fault recovery plan corresponding to the similar known fault. The control device determines, based on the fault recovery plan corresponding to the similar known fault, a fault recovery plan corresponding to the target fault.
