better congestion control in linux

Note to self:

modprobe tcp_westwood
sysctl net.ipv4.tcp_available_congestion_control=westwood

cisco router would “forever change the internet”?

No. It would only mean the peak routing bandwidth across one such router is 322Tbps. It is estimated to be three times the speed of existing systems. So backbone traffic may move a little faster, maybe there will be a little less congestion related losses, but no. It would not forever change the internet. Only applications can do that. So much for the hype.
