Hello,
It seems we forgot about this question. I think you need both: first modprobe
to have the cc in net.ipv4.tcp_available_congestion_control
(and net.ipv4.tcp_allowed_congestion_control
?), then changing sysctl net.ipv4.tcp_congestion_control
I guess you need to change the sysctl except maybe if olia
is set as the default one somehow?
You can use ss -ti
to check which TCP CC is in use.
Do you mind if I close this ticket?
I appreciate your efforts.

Dear All Can I use the following command modprobe mptcp_olia instead of syctl -w net.ipv4.tcp_congestion_control=olia . If I use modprobe mptcp_olia in mininet host then I issue the command iperf3 to calculate throughput, Does that mean that throughput belongs to olia not to default CCA (cubic)?.
when I use mininet host to change CCA through syctl -w net.ipv4.tcp_congestion_control=olia , I experienced the error ( sysctl: cannot stat /proc/sys/net/ipv4.tcp_congestion_control: No such file or directory). I think that MPTCP works correctly with terminal client in kernel but when I use mininet host I had the above mistake.
Briefly: can I use modprobe mptcp_olia instead of sysctl -w net.ipv4.tcp_congestion_control=olia in mininet host in mininet host?. Best Regards
