Abstract: This application discloses an address management method for a virtual broadband gateway (vBNG) in which a user plane and a control plane are separated. A user plane device receives a first packet that includes a private address of a terminal, the user plane device is provided with a public address pool and/or a port number corresponding to each public address in the public address pool. The user plane device generates address translation information of the terminal, where the address translation information of the terminal includes the private address, a public address in the public address pool, and a port number range, the address translation information of the terminal is used by the user plane device to translate an address of a service packet, and the service packet is a packet from the terminal or a packet to be sent to the terminal.

Abstract: A network device having at least one processor and one or more non-transitory memories storing programming instructions that are associated with a steering decision function (SDF) in a network system and including instructions to obtain a carrier-grade network address translation (CGN) resource pool by receiving CGN resources reported by a plurality of user planes (UPs), where the network system includes the SDF, the plurality UPs, and a control plane (CP), receive a CGN instance obtaining request sent by the CP, the CGN instance obtaining request indicating to allocate a CGN instance to a user equipment, allocate a first CGN instance to the user equipment based on the CGN resource pool, the first CGN instance indicating a first UP, of the plurality of UPs, having an available CGN resource, and send the first CGN instance to the CP.
