Abstract Abstract
This document describes extensions to the RSVP Graceful Restart This document describes extensions to the RSVP Graceful Restart
mechanisms defined in RFC 3473. The extensions enable the recovery mechanisms defined in RFC 3473. The extensions enable the recovery
of RSVP signaling state based on the Path message last sent by the of RSVP signaling state based on the Path message last sent by the
node being restarted. Previously defined Graceful Restart node being restarted. Previously defined Graceful Restart
mechanisms, also called recovery from nodal faults, permit recovery mechanisms, also called recovery from nodal faults, permit recovery
of signaling state from adjacent nodes when the data plane has of signaling state from adjacent nodes when the data plane has
retained the associated forwarding state across a restart. These retained the associated forwarding state across a restart. These
mechanisms do not fully support signaling state recovery on ingress mechanisms do not fully support signaling state recovery on ingress
