Abstract: A data flow migration method and device are disclosed. When migration between a source virtual machine and a target virtual machine is started, determining a silent time used for processing data flow migration; and receiving, within the silent time, a data flow packet sent by a switching node; and sending the data flow packet to the target virtual machine according to the data flow packet and a data flow migration policy. In this way, the silent time is used, a newly arrived data flow is redirected, and the newly arrived data flow is directly sent to the target virtual machine according to the data flow migration policy, which avoids migration of the newly arrived data flow. Therefore, data flows that arrive at the source virtual machine are on the decrease, and system migration performance is effectively improved.

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: This application provides a method for determining an access device type, a device, and a system. An access device type is determined by obtaining one or more packet pairs and a time difference of each packet pair. Each packet pair includes a first packet and a second packet, where the second packet is a response to the first packet, and the one or more packet pairs pass through a same access device. Based on this solution, maintenance manpower required for determining an access device type can be reduced, and O&M personnel management complexity of operators or service providers can be reduced.
