Kireeti and Ron,

I requested the slot for presentation of our draft.

Could you give me a 5 minute slot for this presentation?

Thank you.

Title: Crankback Routing Extensions for MPLS Signaling

File-name: draft-iwata-mpls-crankback-04.txt

Authors: Atsushi Iwata, Norihito Fujita, Gerald R. Ash, Adrian Farrel, and 
Simon Marshall-Unitt

Abstract:
   This draft proposes crankback routing extensions for CR-
   LDP signaling and for RSVP-TE signaling.
   Recently, several routing protocol extensions for
   advertising resource information in addition to topology
   information have been proposed for use in distributed
   constraint-based routing.  In such a distributed routing
   environment, however, the information used to compute a
   constraint-based path may be out of date.  This means
   that LSP setup requests may be blocked by links or nodes
   without sufficient resources.
   This draft specifies crankback routing extensions for CR-
   LDP and RSVP-TE so that the label request can be retried
   on an alternate path that detours around the blocked link
   or node upon a setup failure.
   Furthermore, crankback routing schemes can also be
   applied to LSP restoration by indicating the location of
   the failure link or node.  This would significantly
   improve the successful recovery ratio for failed LSPs,
   especially in situations where a large number of setup
   requests are triggered at the same time.
   Crankback has been identified by the ITU-T as requirement
   for the Automatically Switched Optical Network (ASON) and
   should be added to the GMPLS signaling protocols to meet
   this requirement.
