Abstract

   This document describes a number of mechanisms that can be used to
   reduce processing overhead requirements of refresh messages,
   eliminate the state synchronization latency incurred when an RSVP
   (Resource ReserVation Protocol) message is lost and, when desired,
   refreshing state without the transmission of whole refresh messages.
   The same extensions also support reliable RSVP message delivery on a
   per hop basis.  These extension present no backwards compatibility
   issues.
