Some applications require the ability to provide an elevated
probability of session establishment to specific sessions in times of
network congestion.  When supported over the Internet Protocol suite,
this may be facilitated through a network-layer admission control
solution that supports prioritized access to resources (e.g.,
bandwidth).  These resources may be explicitly set aside for
prioritized sessions, or may be shared with other sessions.  This
document specifies extensions to the Resource reSerVation Protocol
(RSVP) that can be used to support such an admission priority
capability at the network layer.

Based on current security concerns, these extensions are intended for
use in a single administrative domain.  [STANDARDS-TRACK]
