Changing TCP initial congestion window
Hello, based on the discussion in http://research.google.com/pubs/pub36640.html, I'd like to change the initial congestion window on a few of my Linux boxes. One way of doing that is by using the 'ip route change' command - something like 'ip route change default via <default gw> dev eth0 metric 100 initcwnd 10'
I was wondering if there is a more generic way of doing this, without having to specify a specific route so that I affects all routes. Thanks! |
The default has been increased in 2.6.39 and later kernels.

Unfortunately, the servers that I need to do this on are running 2.6.18. Also, if I change this using the 'ip route change' command, how do I make it persistent? One option is to add the command to /etc/rc.local but isn't there a way to specify this in /etc/sysconfig... or something? Thanks!
