Abstract

The embodiment of the present application provides a data forwarding method and device, which relate to the communication field and can solve the problem that the relay node cannot forward the data to the correct next hop in the scenario of multi-hop wireless relay network or multi-hop and multi-connection network. node problem. The method is as follows: the first node receives the first data packet; wherein, the first data packet includes the first data and the identification of the second node of the first data; the first node queries the first routing mapping relationship according to the identification of the second node, The third node is determined; wherein, the first routing mapping relationship includes a corresponding relationship between the second node and the third node; the first node forwards the first data to the third node. This application is applied to multi-hop wireless relay networking or multi-hop and multi-connection networking scenarios.

Description

technical field

[0001] The present application relates to the communication field, and in particular to a data forwarding method and device. Background technique

[0002] Compared with the fourth-generation mobile communication technology (4-Generation, 4G), the fifth-generation mobile communication technology (5-Generation, 5G) puts forward more stringent requirements for network capacity indicators and coverage requirements. On the one hand, in order to meet the ultra-high capacity requirements of 5G, it has become a trend to use high-frequency small cells to form a network in hotspot areas, but the cost of providing optical fiber backhaul for densely deployed high-frequency small cells is high and the construction is difficult. On the other hand, in order to meet the wide coverage requirements of 5G, it is necessary to provide network coverage in some remote areas, but providing network coverage in remote areas is difficult and costly to deploy optical fibers. In order t...
