Thank you, Lon More and BrATCO for your fast replies.
EEC document is a near to be perfect reply at my ask. Found it in the morning is a guaranty for the next night
I have made a first diagonal lecture of this document and almost all what I need is provided... Great !
But, I have another conceptual ask...
For a done CFMU 60/60 rate, what's the better way to simulate traffic :
(red value are time of entry in seconds from start)
A) an entry every 60 secs during an hour (surely not, but that's simple to explain...):
i.e.
0 (+ 60)
60 (+ 60)
120 (+ 60)
180...
B) an entry randomly between every 0 to 120 sec during an hour
i.e.
0 (+ RANDOM(0 to 120)=35)
35 (+RANDOM(0 to 120)=105)
150 (+RANDOM (0 to 120)=75)
225 ...
C) the first version with a random shift on each value
i.e.
0 (+ 60=60 + RANDOM)
55 (+ 60=120 + RANDOM)
134 (+ 60=180 + RANDOM)
155...
Or any else.....
Thanks again,
