Thanks Alex for the clarification.
But I still do not know how I can find out which time in
app-delays-trace.txt is for example t4 or t3?
For example I have one consumer that is sending its interests by the rate
of 1 packet/s, size of the each interest is 1KB and the band width is
1Mbps. So what time in .txt file gives me for example t3 and t4 in your
