Abstract: 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 determines, based on a destination address carried in a received first packet, a virtual port corresponding to the destination address in a VPLS instance of the first network device, and sends the first packet to a second VPWS instance in the second network device based on the virtual port, where the virtual port is used to indicate a first VPWS instance in the first network device, and the second VPWS instance and the first VPWS instance are VPWS instances used to bear a same service.

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