I am really confused here. I've read BCP38 (which your paper obliquely
references). I guess you mean: if I have a firewall, I can prevent DOS
attacks from *originating from my network*, as opposed to what I see as
the more popular interpretation of "help you against DOS attacks" to
mean "mitigate the damage of DOS attacks inbound on my network".

I can do all the source filtering I want, but if I'm receiving 500 Mpps
of DDOS, my firewall's gonna keel over and die. (Maybe I'm off by 10 dB
Any plan of action that depends on the compliance of vendors and
everyone else on the Internet is...well, I'd love the IOS command that
would allow me to configure my neighbor's router.
