Is not the problem with this that few if any attacks originate in the
core, and by the time the traffics start getting aggregated there it 
is
already more or less to late?

I'm getting at attacks *on* the core as something we need to be
concerned about...


Ok, then I understand and agree completely!

If protecting the core includes protecting the core from further at the 
edges, then the folks running core components need to require those who 
connect to them to implement such protection (ingress filtering and 
whatever other measures are deemed helpful).

There's some precedent for this type of edict. Some years ago UUNet 
mandated anyone using their dialups MUST implement port 25 filter configs 
in their Radius servers.

Sure seems like a better thing for the core operators to do than throw 
their hands in the air and say "it's someone else's problem."
