I need to use different congestion control algorithms for tcp flow.

How can I continue using those flow congestion algorithms from Fedora 11 in Fedora 17?

Don't change the congestion control algorithm unless you really know what you're doing. – Michael Hampton Mar 26 '13 at 19:14
I suspect you will probably need to recompile your kernel and enable those features. – Zoredache Mar 26 '13 at 19:18

You need to install the kernel-modules-extra package to get these modules.

Not on Fedora 22 it seems. That was also my reflex, but after installing it, only DCTCP is available as a module, the others (which are compiled as modules by Fedora, e.g. YEAH, LP TCP, SCALABLE TCP, etc.) are not installed with this package. – Huygens Sep 16 at 20:30

You can run different congestion control using this command. I.e Congstion Control Algorithm name

sysctl -w net.ipv4.tcp_congestion_control=cubic
