The invention discloses an intermittent communication deep space network data storage and transmission method and aims to provide a method for efficiently transmitting data in an intermittent communication deep space network. According to the technical scheme, aiming at the intermittent communication deep space network data storage and transmission problems, a deep space network sending end converts the end-to-end data transmission into point-to-point hop-by-hop transmission; a sending end node transmits a PDU network layer packet data unit generated by a data link layer to a next node througha protocol data unit PDU, and the next node stores the PDU; a file transmission protocol CFDP unit schedules the protocol data unit PDU; the PDU data frames of the protocol data unit PDU and the datalink layer are transmitted to the next node; and the file transmission protocol (CFDP) unit judges that the ACK is received until all the PDUs are sent. According to the method, the problem that theefficiency of existing forward transmission aiming at link intermittent communication storage and fast transmission is not high is solved.
