AbstractWe study the reliable (acknowledged) operation (i.e., ARQ scheme) of CFDP (CCSDS File Delivery Protocol) over single-hop space link. We focus on the immediate NAK mode, as specified in , under the assumption that PDU error events of forward and backward channels are statistically independent. We point out the problem of duplicated retransmissions due to the long propagation delay and analyze throughput efficiency. We also present modeling and analysis of the average time taken for the delivery of a file with an arbitrary size, which are more rigorous than currently available heuristics.
