[ndnSIM] How to calculate RTT in ndnSIM

[Spyridon (Spyros) Mastorakis]

Hi Gabriel,

correct, that is another way to do that. I typically need to make different decisions in my applications based on the RTT value. That is why I need to be aware of RTT during my simulation rather than looking at the RTT value(s) when the simulation is over. I presumed that the OP may have a similar objective. If not, using the app delay trace should be fine too.

Thanks,

When a data packet comes back, you find the corresponding Interest name in this queue and you calculate the RTT of each Interest/Data exchange. The overall RTT can be the average of the RTT of all the Interest/Data exchanges (or you can use some sort of moving average if you want).
