Yes, AS in the I-D can be read as a BGP AS. In any case, we are just
describing a active measurement model at this point.

Agreed, but the solution described in our I-D considers cooperative peers.
Thus, it is safe to say that it targets single administrative domains which
means that the ACP could be used.

We did not study the applicability of ANIMA solutions for this I-D, but we
have plans to do in a new one if a new ANIMA charter allow such possibility.
