That what makes me think it's not possible to
determine "legal" traffic model by available tools.
The total BW keeps increasing, and network attack
keeps going on. We could estimate traffic scheme by
monitoring BW utilized, but it may has exhaust
customer's server resource when we consider those DoS
packet with our traffic scheme. 

So, Arbor and alike may be useful to enterprise users,
but to ISPs its effectiveness is questionable.

I've discussed with some persons, they just disclame
but no demonstration and analysis.
