The idea is to saturate the link with marked and unmarked packets. However initial results show that the test was not able to reach the maximum bandwidth downstream supported by the link which is about 60Mbps. For unmarked traffic we ran the following test: `flent rrul -H 10.111.40.252` For marked traffic we used the following test: `flent rrul_var -H 10.111.40.252 --test-parameter bidir_streams=5 --test-parameter markings=11,13,15,19,21 ` On both cases we reached no more than 50% of the link capacity. To rule out any problem with the link itself, we ran the following test: `flent tcp_12down -H 10.111.40.252` This time. we were able to reach saturation levels (60Mbps) of downstream traffic. Also ran iperf3 and obtained the same results Do you see any reason why the rrul and rrul_var tests aren't being able to generate enough traffic to saturate the link? Maybe any parameter I'm missing or something? Or maybe that's normal, anyhow, I'd appreciate any comment on this matter. Thanks. -- You are receiving this because you are subscribed to this thread.
