Abstract: This application discloses a method, an apparatus, and a system for constructing a knowledge graph, and a computer storage medium. A first device obtains first configuration information of a target network device. 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.

Abstract: An analysis device obtains connection states of a testing terminal pair that respectively correspond to a plurality of unit moments in a first historical time segment. The testing terminal pair includes a first terminal and a second terminal, the first historical time segment is a time segment before a current time, the first historical time segment includes M consecutive unit moments, and M is a natural number greater than or equal to 2. The analysis device determines, based on the connection states of the testing terminal pair that respectively correspond to the plurality of unit moments in the first historical time segment, a connection state that is of the testing terminal pair and that corresponds to at least one unit moment in a future time segment.

Abstract: A management device obtains network data of a target network. The network data includes a network topology of the target network and device information of a plurality of network devices in the target network, and the device information includes one or more of interface configuration information, protocol configuration information, and service configuration information. The management device extracts a plurality of knowledge graph triplets from the network data. Each knowledge graph triplet includes two network entities and a relationship between the two network entities. The type of the network entity may be a network device, an interface, a protocol, or a service. The management device generates a knowledge graph of the target network based on the plurality of knowledge graph triplets. The knowledge graph of the target network can be used to visualize the network data.

Abstract: A method for restoring a network topology and an apparatus are disclosed. A topology computing apparatus obtains MAC entries of a plurality of network devices; determines a port on which an uplink destination MAC address is learned as an uplink port of the plurality of network devices, where the uplink destination MAC address is a MAC address that appears most frequently in the MAC entries of the plurality of network devices; then determines a plurality of initial sets, and determines a connection relationship between the plurality of network devices based on the plurality of initial sets; and finally determines, based on the connection relationship between the plurality of network devices and the uplink port, a network topology corresponding to the plurality of network devices.

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.
