Abstract: A method for establishing a neighbor relationship, where corresponding authentication information is added to packets that are sent from a first network device and a second network device to each other. The first network device sends a hello packet to the second network device. The second network device receives the hello packet, performs authentication, and responds to the hello packet using an extended unidirectional link (UDL) link state packet (LSP) when the authentication succeeds. The first network device receives the extended UDL LSP, and performs authentication. When an authentication result includes that both the first network device and the second network device enable authentication and the authentication succeeds, a neighbor relationship between the first network device and the second network device may be established.

Abstract: An information transmission method is provided, including: A control device obtains a second universal serial bus video class UVC port and a second virtual network port based on configuration of a universal serial bus USB port of the control device. The control device determines address information of a camera device, where a first UVC port and a first virtual network port are configured on the camera device, and the first UVC port and the first virtual network port are obtained based on configuration of a USB port of the camera device. The control device sends the address information to the camera device through a UVC channel, where the UVC channel is established based on the first UVC port and the second UVC port.
