I have not heard of any problems and have happily done recently:
Ok - I see there is a socket option to pick a different cc per-socket
basis.
Any experiences on loading / using different cc per socket...does it work
seamlessly?
Thanks!

Have you loaded kernel modules for other algorithms? I believe only newreno
is in the default kernel. "man 4 mod_cc" for available modules and other
information.

Hi,
We can set per-socket congestion control under Linux, but not under FreeBSD
(12.0).
The current available and allowed is only newReno:
net.inet.tcp.cc.available: newreno
net.inet.tcp.cc.algorithm: newreno
Any thoughts on why FreeBSD chose not to allow different cc to be set per
socket?
AFAIK,

I was looking at TCP congestion control at work recently and noticed a few
"odd" things in the current code. First, there is this chunk of code in
cc_ack_received() in tcp_input.c:
static void inline
cc_ack_received(struct tcpcb *tp, struct tcphdr *th, uint16_t type)
{
INP_WL
Thanks to each of you.
