    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: Embodiments of this application disclose a tunnel keepalive method, a network device, a system, and a storage medium, and pertain to the field of communications technologies. In the embodiments of this application, before a failure occurs in communication between a UP device and a CP device, the UP device receives tunnel information synchronized by the CP device. After a failure occurs in communication between the UP device and the CP device, the UP device performs tunnel keepalive based on the tunnel information, that is, the UP device maintains a tunnel between the UP device and a remote network device. In this way, tunnel teardown is not triggered because of the failure in communication between the CP device and the UP device.

    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: Embodiments of the present invention relate to a method for acquiring an IP address and a network access device. The method includes: after receiving a first IP address acquiring message from a first network, assigning a first IP address to the first network by using a process and associating an identifier of the first network with a first session, so that the network access device is capable of mapping the first IP address to a first private network IP address and sending the same to the first network, thereby avoiding the problem of complex implementation in the prior art resulted from a process where a gateway configured for a family network or an enterprise network needs to initiate an IPoE dial-up process. In this way, the gateway configured for the family network or the enterprise network is simplified, operation and maintenance costs are reduced, and flat networks are further implemented.

    Abstract translation: 本发明的实施例涉及一种用于获取IP地址和网络接入设备的方法。 该方法包括:在从第一网络接收到第一IP地址获取消息之后,通过使用处理并将第一网络的标识符与第一会话相关联来向第一网络分配第一IP地址,使得网络接入设备 能够将第一IP地址映射到第一专用网络IP地址并将其发送到第一网络,从而避免了现有技术中由配置用于家庭网络或企业网络的网关的过程导致的复杂实现的问题 需要启动IPoE拨号过程。 以这种方式,为家庭网络或企业网络配置的网关简化,降低了运营和维护成本,进一步实现了平面网络。
