Doesn't ECN depend on 'well behaved' traffic? In other words, wouldn't it
require the hosts sending traffic to slow down? So... even if the hosts
slowed down, 10,000 hosts still is a high traffic rate at the end point.
:(

Yes, for ECN to work the sending host must honor the slowdown request/ It
does happen transparently for most types of sockets, however the attacker
can and will disable ECN with a single syscall.
