Reservation confirmation is initiated by the receiver, which sends the Resv message with an object

resources are reserved on the farthest upstream node where the Resv message arrived and the resources
can be preempted.

network resources.
It requires that the interfaces at the two ends of a link must share the same authentication key to exchange
RSVP messages.
