Abstract: Example data transmission methods and apparatus are described. In one example method, a data distribution point obtains a first correspondence between a first virtual extensible local area network identifier (VXLAN ID) and an address of a first terminal. The data distribution point receives a first VXLAN packet based on a tunnel of a first VXLAN, where the first VXLAN packet includes the first VXLAN ID and first data. The address of the first terminal is determined based on the first VXLAN ID carried in the first VXLAN packet and the first correspondence. The first distribution point sends the first data to the first terminal based on the address of the first terminal.

Abstract: A Border Gateway Protocol Monitoring Protocol (BMP) module sends to a Border Gateway Protocol (BGP) module a request for acquiring a capability information set; the BGP module traverses BGP capability data stored in the BGP module to acquire all BGP capability data configured in the network device and sends all the BGP capability to the BMP module; and the BMP module sends to the monitoring server an initial capability information set message carrying all the BGP capability data and a device identifier of the network device. By means of capability extension of a network device, the network device can acquire, through interaction between a BGP module and a BMP module, all BGP capabilities configured in the network device and send all the BGP capabilities to a monitoring server, so that the monitoring server can fully understand actual capability supported by the entire network, further providing an effective basis for deployment of and decision on the entire network.

Abstract: This application provides a path determining method and a related device. The method includes: determining N1 first-type nodes from N nodes included in a first network topology, where the N nodes include the N1 first-type nodes and N2 second-type nodes, and the first-type node supports SRv6; determining a second network topology corresponding to the first network topology, where the second network topology includes the N1 first-type nodes but does not include the N2 second-type nodes, and the target topology structure includes M first-type target paths; determining transmission overheads of the M first-type target paths, where a transmission overhead of an ith first-type target path is a smallest value of transmission overheads of a Ki paths; and performing path computation based on the transmission overheads of the M first-type target paths and the second network topology.

Abstract: A network device creates a virtual border gateway protocol (BGP) peer and the BGP peer is enabled all BGP capability data configured in the network device. A BGP monitoring protocol (BMP) module of the network device acquires the enabled BGP capability by using a BGP message. According to the solution of the embodiment, the network device obtains all BGP capabilities configured in the network device and sends all the BGP capabilities to a monitoring server, so that the monitoring server can fully understand actual capability supported by the entire network, further providing an effective basis for deployment of and decision on the entire network.

Abstract: The present disclosure provides a method, an apparatus, and a system for collecting an access control list. A second network device receives a first LSA packet flooded by a first network device, where the first LSA packet includes a first network device identifier and first ACL information, and the first network device and the second network device belong to a same IGP area; and sends an extended first BGP-LS packet to a controller, where the extended first BGP-LS packet includes the first network device identifier and the first ACL information, so that the controller can collect ACL information of the first network device and manage the ACL information of the first network device.
