To support the file transferring in deep space communication environment,the Consultative Committee for Space Data Systems(CCSDS) File Delivery Protocol(CFDP) was developed.The prompt negative acknowledgment(NAK) mode was analyzed,and a deferred-prompt trigger method and automatic repeat-request(ARQ) timer setting rule for the single-hop point-to-point file transfer operation was proposed,which minimized the expected time taken to transfer a file under the constraint of the maximized throughput.Performance measures was mainly concerned for the expected file delivery time and compared with the other NAK modes,the simulation results show that deferred-prompt NAK mode has a better performance in conditions.
