This paper examines the performance of the Digital Smart Technologies for Amateur Radio-Digital Data mode with various IP and non-IP based protocols. A throughput comparison was performed between IPv4, IPv6, the DTN Convergence Layer and the NORM Convergence Layer. The experimental results show that the DTN NORM Convergence Layer exhibits better performance than TCP/IP, and appears to perform better over difficult radio links.
