Abstract: This application discloses a communication method, apparatus, device, and system, and a computer-readable storage medium, and relates to the field of communication technologies. The method includes: A CP device receives a first packet that is sent by a first UP device and that carries source information of a first user terminal; searches, based on the source information of the first user terminal, a correspondence between source information of a user terminal and a location identifier of the user terminal accessing a network, to determine a first location identifier of the first user terminal accessing a network; and sends the first location identifier to a USF device.

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 BRAS system-based packet encapsulation method includes obtaining user access information when receiving a user access protocol packet and performing VXLAN GPE encapsulation on the user access protocol packet based on the user access information. The encapsulation structure includes a user information header that is used to store the user access information, and a quantity of bytes occupied by the user information header is less than or equal to 12. In this application, the foregoing encapsulation structure is used to encapsulate a packet.

Abstract: This application provides a communication method, a UP device, and a CP device, and pertains to the field of communications technologies. In the method, the UP device reports interface information to the CP device by using PFCP. Specifically, the UP device carries the interface information in a PFCP message, and transmits the PFCP message to the CP device. The CP device can obtain the interface information of the UP device from the PFCP message, which ensures that the CP device can sense the interface information of the UP device.

Abstract: A network dial-up method includes: performing a negotiation in a Point-to-Point Protocol (PPP) discovery stage for each dial-up request respectively when more than one dial-up request is received,; creating a virtual PPP interface for each dial-up request; configuring the virtual PPP interfaces; coupling the virtual PPP interfaces to a physical PPP interface, where the physical PPP interface is coupled to more than one of the virtual PPP interfaces, and the physical PPP interface performs round robin processing for the virtual PPP interfaces; and performing negotiations in a PPP session stage by way of the virtual PPP interfaces, thereby succeeding in dial-up after completing the negotiations in the PPP session stage.
