Abstract

Embodiments of this application relates to a communication method and a related device. In an example, a device receives a first data packet in a first network segment, the first data packet comprises a first backhaul adaptation protocol (BAP) routing identity, and the first BAP routing identity is used for transmission of the first data packet in the first network segment. The device further obtains a first correspondence. In response to determining that the first correspondence comprises the first BAP routing identity in the first data packet, the device determines that the first data packet meets a preset condition. In response to that the first data packet meets the preset condition, the device replaces the first BAP routing identity in the first data packet with a second BAP routing identity according to the first correspondence, to obtain a second data packet.
