The Consultative Committee For Space Data Systems (CCSDS) file delivery protocol (CFDP) offers selectable quality of service, according to mission requirements and transmission capability, ranging from an unacknowledged option to a fully acknowledged option providing error recovery through retransmission. The performance of CFDP in the deferred NAK mode has been evaluated in a theoretical manner. In this paper, we present an experimental performance evaluation of CFDP in the deferred NAK mode over the direct, point-to-point geostationary earth orbit (GEO)-satellite links simulated using a test-bed. We compare CFDP running over TCP with the CCSDS space communication protocol standards (SCPS) protocol stack to see which one is more effective over a GEO-satellite link. The experimental results show that CFDP does not have performance advantage over other protocols over a less lossy channel with a BER less than or equal to 10-6. However, along with the increase of BER, CFDP shows significant performance advantage. Quantitatively, for a symmetric channel with BER=10-5, CFDP-TCP protocol has the highest throughput which is 2000 bytes/sec higher than SCPS-VJ and almost 3500 bytes/sec higher than SCPS-Vegas. The throughput advantage of CFDP with BER=10-5 is 1500 bytes/sec over SCPS-VJ and 2800 bytes/sec over SCPS- Vegas, over asymmetric channel with BER=10-5.
