Abstract: A gateway device selection method is provided. The method includes: receiving, by a terminal device, a message from a gateway device, where the message includes identification information of the gateway device, and the identification information of the gateway device indicates information about the gateway device; determining, by the terminal device, that the identification information of the gateway device is consistent with preset identification information of a gateway device on the terminal device, and using the gateway device as a selected gateway device; and sending, by the terminal device, a data packet to the selected gateway device. This helps the terminal device correctly identify the gateway device to which the terminal device is to send data.

Abstract: This application provides an address detection method and a related apparatus. The method includes: receiving a first internet protocol (internet protocol, IP) address from a first device, where the first IP address is a to-be-detected IP address of the first device; determining a first information table, where the first information table includes an IP address of one or more devices, and the one or more devices and a first apparatus are at a media access control layer of a same network; determining a second information table based on the first information table; and detecting whether a second IP address that is the same as the first IP address exists in the second information table, where a first media access control address corresponding to the first IP address is different from a second media access control address corresponding to the second IP address.
