    Abstract: Embodiments of this application disclose a group-based calibration method and device. The method includes: A control device that obtains path loss data of a wireless access point AP set, where the AP set includes a plurality of APs, and the path loss data includes a path loss between any two of the plurality of APs. The control device obtains a first calibration group based on the path loss data, and sends first calibration information to a management AP of the first calibration group, where the management AP of the first calibration group is an AP that performs calibration management in the first calibration group. By implementing the foregoing method, the control device may divide a plurality of APs into a plurality of calibration groups based on path loss data between the APs, to decrease a coupling degree between the calibration groups.

    Abstract: A fault root cause identification method, apparatus, and device. For a failure flow that occurs when a connectivity fault for access in a network occurs, a target success flow that has a high similarity with the failure flow is determined from a plurality of success flows in the network based on the failure flow. Then, a target fault root cause of the failure flow is obtained based on the failure flow, the target success flow, and a trained first machine learning model. In this way, the target success flow related to the failure flow is determined from the plurality of success flows in the network, and the first machine learning model trained by using a large quantity of success flows and failure flows whose feature indicators are slightly different from each other is used.

    Abstract: An alarm log compression method, apparatus, system, and a storage medium are provided. The method includes: obtaining a historical alarm log set generated by a first network device; dividing the historical alarm log set into a plurality of historical alarm log subsets based on a generation time stamp of a historical alarm log in the historical alarm log set, where all historical alarm logs in each historical alarm log subset are consecutive in a time sequence; determining a correspondence between an alarm type in the historical alarm log set and the plurality of historical alarm log subsets; performing clustering processing on the alarm types in the historical alarm log set based on the correspondence, to generate at least one association rule; and compressing to-be-processed alarm logs based on the at least one association rule, to obtain an alarm log whose alarm type is a root cause alarm type.
