- Hi,

Please capture your incoming traffic with Wireshark and check your 
throughput. I'm pretty sure that the ping command does not support 
sending packets with an interval of 0.004 second.


- Apparently it's indeed a ping problem... However it's quite strange 
because yesterday we (with Emmanuel Lochin) tested the ping with tshark 
and it supported sending packets with an interval down to 0.001 second.
Nevertheless the average throughput is coherent when we use longer pings 
(it seems the throughput remains coherent with intervals down to 10ms) .


There should be an error with initial statistics, I will investigate on 
that. Could you please check the file where this statistic is saved to 
tell me if you find the 6000000 value in it (else this is a manager 
problem). The file should be in 
~/.opensand/default/<your_run_id>/st1/st/Throughputs.L2_from_SAT.csv


- We checked the file you mentionned and indeed the first value for 16ms 
is about 60000000 Kb/s.

Regards,

Jonas and François.
