AbstractIn CCSDS File Delivery Protocol (CFDP), four acknowledged modes essentially have an identical protocol for initializing and closing a file delivery. In this protocol, the system occasionally run into a state in which Sender has closed the transaction and Receiver has not closed the transaction. In this paper, we point out the danger of such state being prolonged. Such a state can be prolonged due to link occultation, extremely long propagation delay, or implementation caused by common misinterpretation of the protocol specification. We provide two failure scenarios, which occur in such a state. Then, we discuss ways of preventing such failures.
