Great paper, although you left out that as long as someone is making money either allowing the attacks to be originated by not enabling uRPF (in the case of many hosting companies) or transiting the traffic (How much of this wayward UDP traffic turns into revenue at the carriers?) the incentive profile is upside down.

Many carriers won't filter these attacks upstream because if the traffic doesn't hit your port they can't bill you for it.

So they're making money off of it.
