Transport protocols revisited

This paper evaluates and compares the performance of various transport protocols over some current tactical radios using different topologies. The four selected transport protocols were TCP, SCTP, UDT, and Mockets. The comparison was done with three different tactically relevant radios - the Harris PRC-117G, the TrellisWare TW-400, and the Persistent Systems WaveRelay MPU4. The results show a surprising amount of variability in performance, and indicate that the Mockets transport protocol provided the best overall performance on two of the three radios used for evaluation.
