Dear,

We just posted a new I-D: draft-li-ccamp-multinodes-gr-proc-00.txt for which your comments are very welcome! The following is the abstract of this new I-D, please check out the attachment for details.

This document only clarifies the control plane procedures for a GMPLS network when there are multiple node failures, and describes how full control plane state can be recovered depending on the order in which the nodes restart. We know there still have some issues which we have not awared of, so we strongly encourage you to send your comments to this mailing list.

Abstract 

   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 clarifies the control plane procedures for a GMPLS 
   network when there are multiple node failures, and describes how full 
   control plane state can be recovered depending on the order in which 
   the nodes restart. 

Best regards,

Dan Li
