I belive the biggest component comes from link-layer retransmissions.
There can also be some short outtages thanks to signal blocking,
tunnels, people with big hats and whatnot that the link-layer
retransmissions are trying to address. The three seconds seems to be a
value that gives the certainty that 99 times out of 10 the segment was
indeed lost.
The trace I've been sent shows clean RTTs ranging from ~200 milliseconds
to ~7000 milliseconds.
Thanks for the info.
It's pretty easy to generate examples where we might have some sockets
talking over interfaces on such a network and others which are not.
Therefore, if we do this, a per-route metric is probably the best bet.
This is exactly what I was thinking. It might even help discourage
users from playing with this setting who should not. ;)
