Actually, no - it is not. RSVP does *not* mandate per-flow traffic handling.
When I speak about work that has been done to make the RSVP approach more
scalable, one of the key aspect of this work is coupling per-flow
reservation with aggregate (diffserv) traffic handling. 

Please keep the two separate. The scaling characteristics of listening to
one message per flow, every 30 seconds, are very very different from those
of policing/scheduling every packet on each flow.
