Abstract: In a forwarding fault location determining method, a controller receives a plurality of table search statistical results of a plurality of forwarding tables for a first service from one or more forwarders. The plurality of forwarding tables include a first forwarding table and a second forwarding table, and the first forwarding table is prior to the second forwarding table in terms of a search sequence. Subsequently, the controller determines that table search behavior of the first forwarding table for the first service is normal and table search behavior of the second forwarding table for the first service is abnormal. The controller determines, based on the determining result, that the second forwarding table is a faulty forwarding table for the first service.

Abstract: This application provides a method for federated learning. A communication apparatus triggers, by setting a threshold (a time threshold and/or a count threshold), fusion of a local model sent by a terminal device, to generate a global model, and when a fusion weight of the local model is designed, a data feature included in the local model of the terminal device, a lag degree, and a utilization degree of a data feature of a sample set of the corresponding terminal device are comprehensively considered, so that a problem of low training efficiency caused by a synchronization requirement for model uploading versions in a synchronous system can be avoided, and a problem of unstable convergence and a poor generalization capability caused by an “update upon reception” principle of an asynchronous system can be avoided.

Abstract: This application discloses a method, an apparatus, and a system for constructing a knowledge graph, and a computer storage medium.

The first device obtains a template matching file corresponding to the target network device, where the template matching file describes one or more formats of one or more command lines in configuration information of a type of network device to which the target network device belongs. Then, the first device creates, based on the template matching file and a first command line in the first configuration information, a target network entity corresponding to the first command line. A type of the target network entity is a device, an interface, a protocol, or a service. The target network entity is configured to construct a knowledge graph of a network in which the target network device is located.
