I like this sysctl politic. I find useful to switch between NewReno, Vegas and other congestion control algorithms at runtime, enable Westwood or tune Vegas without having to reboot. Expecially when testing them.

What if someone introduces a new congestion control algorithm implementation? How could you switch between them? As I am actually working on another experimental congestion control algo, my current kernel implements an integer parameter to switch between CCAs, something like
sysctl_tcp_cong_avoid_algo [0 = NewReno (default), 1 = Vegas, 2 = Hybla, 3=...]
Obviously this wouldn't affect Westwood and other enhancements which don't alter tcp_cong_avoid().
