Performance Measurements of Applications using IP over HF Radio
This paper sets out the results of measurements made when running applications and layer protocols to support applications over IP via HF Radio using STANAG 5066. The goal of this work was to get a quantitative measure of the performance impact of using applications running over IP over HF Radio in comparison with applications running directly over specialized HF Radio protocols. This paper concludes that the performance impact of using IP is massive, with small message latency increase from at typical value of 6-20 seconds using applications optimized for HF to a smallest measured value of 89 seconds when using IP.
