GTSM - Do you use it?

[John Smith]

Hi,
 
I would like to know if operators use GTSM techniques with BGP and other 
routing protocols today? Is any at the perimeter of the routing domain 
deployed? I would believe that GTSM can provide protection against attacks more 
than a hop away and thus can save against a lot of potential Dos attacks.
 
Is anything done by the operators here?
 
Thanks,
John
