RSVP may not apply the reservation, but it relies on it to function.
Without reservation, how could RSVP generate a ResvErr message with
Error Code 1, Sub-code 2: Requested bandwidth unavailable, for example?
The definition of "available bandwidth" changes dramatically without
resource reservation.
