Abstract: A communication method, a device, and a system are disclosed. An SF device adds a first location identifier including an identifier of the SF device and an identifier of a first physical port to a received first packet sent by first user equipment, and sends a second packet to which the first location identifier is added to a first UP device. The first UP device sends a third packet to a CP device, and the CP device sends the third packet to a USF device. The USF device interacts with an SDN controller, to enable the SDN controller to deliver a configuration instruction to the corresponding SF device. The first packet may be a DHCP packet or a PPPoE packet, and OPTION82/OPTION18 is added to carry the first location identifier.

Abstract: A broadband connection method includes a virtual broadband network gateway (vBNG)-control plane (CP) that receives first indication information from a user plane selection function (USF), where the first indication information indicates a second vBNG-user plane (UP) that replaces a first vBNG-UP when the first vBNG-UP is faulty. The vBNG-CP sends a user entry to the second vBNG-UP based on the first indication information, where the user entry is used by the second vBNG-UP to enable a user to access a network based on the user entry when the first vBNG-UP is faulty such that when a user plane is faulty, broadband access of a user is not interrupted, and the user can continue to access a network.

Abstract: This application provides a communication method, a CP device, and a NAT device; pertains to the field of communication technologies; and relate to a scenario of performing NAT tracing based on a CU-separated BNG. The CP device delivers, to the NAT device, an IP address assigned to a user. Under a trigger condition of receiving the IP address delivered by the CP device, the NAT device assigns a public network IP address to the user, and reports the public network IP address to the CP device. The CP device adds, to an accounting packet, the IP address assigned by the CP device and the public network IP address assigned by the NAT device, and sends the accounting packet to a RADIUS server, to report the public network IP address to the RADIUS server, so that the NAT tracing is performed on the RADIUS server.
