What you want from the probe is predictability in the form of minimal jitter and possibly some calibration (to equate latency). IF the Turris people can run the Atlas code with some sort of real-time scheduling then it is going to be OK as a probe. Can they?
It depends on what level of control you need. The board will be supported by vanilla Linux kernel (we are almost there). So you/we can compile in whatever is needed.
Schedule determinism (some sort of real time kernel extension) : to send probe traffic in a predictable manner Accurate time-of-arrival stamping for incoming packets, so you can trust the measurement. Joao
