摘要： This application discloses a method and an apparatus for accessing a gateway, and pertains to the field of communications technologies. In this application, an SLA level may be obtained based on user information of a terminal, and further a UP device corresponding to the terminal is determined based on the SLA level of the terminal. In this way, 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.

摘要： 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, so that the USF device can determine that the first user terminal accesses the network from a first physical port on a first SF device, and configure a second SF device by using a controller, to switch traffic from the first user terminal from a first sub-interface that is on the first SF device and that corresponds to the first UP device to a second sub-interface that is on the second SF device and that corresponds to a second UP device, thereby sending traffic of a static user to an appropriate UP device.

摘要： A method for accessing a gateway and an apparatus are disclosed, relate to the field of communication technologies, and are applied to a network system including a virtual broadband network gateway vBNG, where the vBNG includes a control plane CP device and a plurality of UP devices managed by the CP device, and the network system further includes a user plane steering function USF device. The method includes: The USF device obtains user information of a target terminal; the USF device determines a target UP device in the plurality of UP devices based on the user information and load of the plurality of UP devices; and the USF device indicates the target terminal to access the target UP device. Therefore, an appropriate UP device is selected for the target terminal in the network system including the vBNG, and load balancing between the plurality of UP devices is implemented.

摘要： A packet transmission method, device, and system are disclosed, and pertain to the field of network technologies. The system includes a first network device in a VPLS network and a second network device in a VPWS network. The first network device receives, by using a first VPLS instance in the first network device, a packet to be sent to a user-side device connected to the second network device, determines a first VPWS instance in the first network device based on an association relationship between the first VPLS instance and the first VPWS instance, and forwards the packet to a second VPWS instance in the second network device by using the first VPWS instance. A VPLS instance is associated with a VPWS instance in the first network device, so that a packet that is received by using the VPLS instance and that is to be sent to a user-side device can be forwarded by using the associated VPWS instance, pressure on the first network device to learn a MAC address for packet transmission is reduced, and forwarding performance of the system is ensured.

摘要： This application provides a packet transmission method, apparatus, and system, and relates to the field of network technologies, to improve utilization of a user-side link and reduce load on the user-side link. 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. Packets of the user terminal are forwarded to the first forwarding device and the second forwarding device in a load balancing mode. 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.

摘要： This application relates to a method for generating a detection policy, a device, and a system. The method is applied to a software defined network SDN controller. The method includes: The SDN controller obtains path information, where the path information includes information about a first network device, and the first network device belongs to a network device through which a packet passes from a source end to a destination end. The SDN controller generates a detection policy for a second network device based on the path information, and delivers the detection policy to the second network device, where the second network device is the same as or different from the first network device.

摘要： This application discloses a traffic sending method, apparatus, and system, and a storage medium, and belongs to the communication field. The method includes: A control plane device obtains, based on a packet sent by a terminal, a first service function combination corresponding to the terminal, where the first service function combination includes at least one service function. The control plane device configures a first policy on a user plane device based on the first service function combination, where the user plane device is a user plane device accessed by the terminal, the first policy indicates a first service chain, and the first service chain corresponds to the first service function combination. The control plane device sends first user entry information to the user plane device, where the first user entry information includes an identifier of the first policy and an identifier of the terminal, and the first user entry information indicates the user plane device to send traffic from the terminal to the first service chain based on the first policy. In this application, fewer storage resources of a user plane device and a server can be consumed, and fewer policy resources can be consumed.

摘要： 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. Because the NAT tracing uses a RADIUS tracing manner, this manner is free from limitation that a log server needs to be established for the NAT tracing. Therefore, the costs of establishing the log server are omitted.
