Intersatellite routing fault tolerance method and device, electronic equipment and storage medium

The invention provides an inter-satellite routing fault tolerance method and device, electronic equipment and a storage medium, and the method comprises the steps: determining whether a second node connected with a first node works normally or not when a to-be-transmitted data packet is transmitted in a transmission route, and enabling the first node and the second node to be nodes in the transmission route, the second node is the next node connected with the first node; when it is determined that the second node works abnormally, a third node connected with the second node is determined in the transmission route, and the third node is the next node connected with the second node; determining candidate nodes in the inter-satellite route according to the first node and the third node; and performing route recovery on the transmission route according to the candidate nodes. The dynamic and timely recovery of the route is realized, and the stability of the inter-satellite route and the timeliness and accuracy of
