Abstract

In non-packet transport networks, there are requirements wherethe Generalized Multiprotocol Label Switching (GMPLS) end-to-endrecovery scheme needs to employ a restoration Label Switched Path (LSP)while keeping resources for the working and/or protecting LSPsreserved in the network after the failure occurs.

This document reviews how the LSP association is to be provided usingResource Reservation Protocol - Traffic Engineering (RSVP-TE)signaling in the context of a GMPLS end-to-end recovery scheme whenusing restoration LSP where failed LSP is not torn down. Inaddition, this document discusses resource sharing-based setup andteardown of LSPs as well as LSP reversion procedures. No newsignaling extensions are defined by this document, and it is strictlyinformative in nature.
