Abstract: This application discloses a path determining method and apparatus, and a computer storage medium, and pertains to the field of network technologies. An analysis device first determines a source network entity and a destination network entity on a knowledge graph of a target network, where the knowledge graph includes a plurality of knowledge graph triplets, each knowledge graph triplet includes two network entities and a relationship between the two network entities, and a type of the network entity is a device, an interface, a protocol, or a service. Then, the analysis device determines, on the knowledge graph, a transmission path from the source network entity to the destination network entity.

Abstract: This application discloses an access management method, an authenticator, and an authentication server, applied to a scenario in which a terminal device accesses a network. After completing authentication, a terminal device sends a first packet to an authenticator, where the first packet carries a first IPv6 address of the terminal device and a MAC address of the terminal device. When determining that the first IPv6 address is a new IPv6 address, the authenticator sends, to an authentication server, a second packet carrying the first IPv6 address and the MAC address, so as to indicate the authentication server to send a first authorization policy to a policy enforcement point based on the first IPv6 address.

Abstract: A traffic detection method, apparatus, and system are provided. A first network device obtains a packet, where the packet is any packet of the traffic. The first network device adds a detection flag and detection indication information to the packet to update the packet, where the detection flag is used to indicate a position of the detection indication information, where the detection indication information includes a first flag, and the first flag is used to indicate whether the traffic is to-be-detected traffic. The first network device sends an updated packet to a second network device. According to this method, traffic performance is detected, and flexibility and extensiveness of traffic performance detection are improved.
