Default TCP/IPV4 congestion control should be CUBIC
Last modified: 2007-11-30 17:12:09 EST
NO cubic, highspeed, htcp, hybla, illinois, scalable, vegas, veno, westwood or
yeah. Only reno and bic !!
querida:~ # head /proc/sys/net/ipv4/*_congestion_control
==> tcp_allowed_congestion_control <==
==> tcp_available_congestion_control <==
==> tcp_congestion_control <==
and please make cubic default. It was changed in 2.6.19, so it must be safe.
they were built as modules, only two missing: illinois and yeah.
We build all of the modules that are available in linux 2.6.21. Illinois and
yeah are 2.6.22 only.
The default has now been changed to cubic in rawhide, we will probably change it
in F7 and FC6 as well.
Changed Fedora 7 to cubic, will be in next release after 1.3255.fc7.
