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.

Abstract: Embodiments of this application provide a lossless data transmission communication method, apparatus, and system. The method includes: A first network node determines a first data packet. A destination node of the first data packet is a third network node or a security gateway on the third network node side. The third network node is a source donor node or a source donor node central unit (CU) of the first network node. The first network node sends the first data packet to a second network node. The second network node is a target donor node distributed unit DU of the first network node. According to the method, a data packet loss in a topology update process of the first network node can be avoided, and service continuity can be ensured.
