A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Traffic Engineering Architecture and Signaling of the IETF.

   In non-packet transport networks, there are requirements where
   Generalized Multi-Protocol Label Switching (GMPLS) end-to-end
   recovery scheme needs to employ restoration Label Switched Path (LSP)
   while keeping resources for the working and/or protecting LSPs
   reserved in the network after the failure occurs.

   This document reviews how the LSP association is to be provided using
   Resource Reservation Protocol - Traffic Engineering (RSVP-TE)
   signaling in the context of GMPLS end-to-end recovery scheme when
   using restoration LSP where failed LSP is not torn down.  In
   addition, this document discusses resource sharing-based setup and
   teardown of LSPs as well as LSP reversion procedures.  No new
   signaling extensions are defined by this document, and it is strictly
   informative in nature.
