摘要： 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 (for example, a campus 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. The authenticator can send the new IPv6 address to the authentication server, to enable the authentication server to formulate the first authorization policy for network admission based on the first IPv6 address. Therefore, a service packet of the terminal device can be transmitted, through the policy enforcement point, to an address or a network segment that allows a user to access. Therefore, even if the IPv6 address of the terminal device changes, it can be ensured, as much as possible, that a service is not interrupted.

摘要： 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. In this application, a path does not need to be determined depending on a service packet transmission scenario, and therefore path determining flexibility is high.

摘要： A traffic detection method, apparatus, and system are provided. The method includes: 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, 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.
