    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.

    Abstract: This application relates to message sending and receiving methods and apparatuses, and a communication system. A control plane CP device in a communication system in which a CP and a user plane UP are separated generates a first message, where the first message includes route information and a control indication for the route information, and the route information is associated with a UP device. The CP device sends the first message to the UP device, so that the UP device updates the route information based on the control indication, where the first message is a packet forwarding control protocol PFCP message. Based on the technical solutions provided herein, interaction on routing control between the CP device and the UP device in a communication system architecture in which a CP and a UP are separated may be implemented.

    Abstract: This application provides a packet transmission method, apparatus, and system, and relates to the field of network technologies. The method is applied to a network architecture including a user terminal, a first forwarding device and a second forwarding device. A tunnel is disposed between the first forwarding device and the second forwarding device. The method includes: The first forwarding device receives packets forwarded by the user terminal in the load balancing mode, where the packets include a keepalive packet, and the first forwarding device is a standby forwarding device corresponding to the user terminal. The first forwarding device forwards the keepalive packet to the second forwarding device through the tunnel, where the second forwarding device is an active forwarding device corresponding to the user terminal.

    Abstract: A network attack defense policy sending method and apparatus are presented. The method includes receiving attack information which includes a target Internet Protocol (IP) address, and the attack information is used to indicate that a network attack packet whose destination address is the target IP address exists in a first network; determining that the network attack packet enters the first network through a first edge network device, where the first edge network device is an edge device in the first network; sending a defense policy to the first edge network device, where the defense policy is used to instruct the first edge network device to process, according to the defense policy, a packet whose destination address is the target IP address. By means of this application, network resources occupied by a network attack packet can be reduced, and an effect of defending against the network attack packet can be improved.

    Abstract: This application discloses a method and an apparatus for accessing a gateway, and pertains to the field of communications technologies. A service level agreement (SLA) level may be obtained based on user information of a terminal, and further a user plane (UP) device corresponding to the terminal is determined based on the SLA level of the terminal. Thus, terminals with different SLA levels may be allocated to different UP devices for bearing, so that a specific terminal may access a specified UP device. This resolves a problem in a related technology that a terminal relatively randomly accesses a UP device. In addition, because an SLA level may be used to indicate a level of quality of service of a terminal, after terminals with different SLA levels access different UP devices, differentiated services may be provided on the different UP devices. Therefore, user requirements are met, and revenues are increased.
