The present disclosure provides a
data transmission method, device and equipment, and a storage medium, relating to the technical field of computer. The method comprises: determining a current
satellite holding a data packet; wherein the data packet is a data packet sent from a first
satellite to a second
satellite, the first satellite is in communication connection with a first call terminal, and the second satellite is in communication connection with a second call terminal; determining at least one transmission path between the current satellite and the second satellite; determining a target path from the at least one transmission path according to link connection information in the transmission path; and transmitting the data packet to a next satellite of the current satellite in the target path. The method can dynamically select a target path from the current satellite to the second satellite according to multi-dimensional information such as the topology structure change of the
satellite network and the link connection information, and determine the next hop satellite based on the target path, thereby ensuring the
reliable transmission of the data packet between satellites and realizing high-quality
satellite telephone communication between the first call terminal and the second call terminal.
