Well, in case you're being DDoS:ed at 1 gigabit/s, you'll use more 
resources in the backbone than most, by some definition of "you".

So my take is that this is impossible to solve in the core because routers 
can't keep track of individual conversations and act on them, doing so 
would increase cost and complexity enormously.
