Title : Description of the RSVP-TE Graceful Restart Procedures
Author(s) : D. Li, et al.
Filename : draft-ietf-ccamp-gr-description-04.txt
Pages : 19

The Hello message for the Resource Reservation Protocol (RSVP) has
been defined to establish and maintain basic signaling node
adjacencies for Label Switching Routers (LSRs) participating in a
Multiprotocol Label Switching (MPLS) traffic engineered (TE)
network. The Hello message has been extended for use in Generalized
MPLS (GMPLS) network for state recovery of control channel or nodal
faults.
GMPLS protocol definitions for RSVP also allow a restarting node to
learn the label that it previously allocated for use on a Label
Switching Path (LSP).
Further RSVP protocol extensions have been defined to enable a
restarting node to recover full control plane state by exchanging
RSVP messages with its upstream and downstream neighbors.
This document provides an informational clarification of the
control plane procedures for a GMPLS network when there are
multiple node failures, and describes how full control plane state
can be recovered in different scenarios where the order in which
the nodes restart is different.
This document does not define any new processes or procedures. All
protocol mechanisms are already defined in the referenced documents.
