The embodiment of the invention provides a routing selection method and device. The method comprises the following steps: obtaining a data request containing a content prefix in a node, and when information corresponding to the content prefix is found in a forwarding information base FIB corresponding to the node, determining all interfaces corresponding to the content prefix in the FIB; obtaining position information and speed information of adjacent nodes corresponding to all interfaces separately; predicting survival times of routings corresponding to all the interfaces respectively according to the position information and the speed information; determining available probabilities of the routings corresponding to all the interfaces respectively according to the survival times; and determining the routing corresponding to the maximum available probability in the routings corresponding to all interfaces respectively as the routing corresponding to the data request. By adoption of the routing selection method and device provided by the embodiment of the invention, the effect of improving the data request efficiency and the utilization rate of network resources can be realized.
