Juha,

As I understand it, no assumption is made about how the traffic is
actually treated.  RSVP simply communicates traffic characterizations
and requirements.  What implementation do with that will vary.  Best
effort usually carries no reservation, as it is the default.  What the
router does to accomodate best effort traffic is outside of the scope
of int-serv or rsvp.  Of course some treatments will provide better
service than others in terms of fairness, goodput, delay, etc.

Perhaps you mean elastic traffic rather than best effort?
