Abstract
This document describes protocol-specific procedures and extensions
for Generalized Multi-Protocol Label Switching (GMPLS) Resource
ReSerVation Protocol - Traffic Engineering (RSVP-TE) signaling to
support end-to-end Label Switched Path (LSP) recovery that denotes
protection and restoration. A generic functional description of
GMPLS recovery can be found in a companion document, RFC 4426.
