=> The requirements discussion is seaprate from my 
comments on the problem statement. I would have liked
to send them earlier too, but as I said it's a very 
common holiday period. Perhaps something to think about
with future last calls.

=> Then it should be explicitly stated that the 
anticipation is 'AR-based'. Simply saying 
'anticipation' in isolation and not mentioning
this term in ch 4.2 is misleading because it associates
'anticipation' with a certain mechanism.

=> Exactly, I think 'access router- based' is more
appropriate.
