     Internet-Draft  draft-ietf-pce-remote-initiated-gmpls-lsp-05.txt

     Abstract 

     RFC8281 specifies procedures that can be used for creation
     and deletion of PCE-initiated LSPs in the active stateful PCE model.
     However, this specification focuses on MPLS networks, and does not
     cover remote instantiation of paths in GMPLS-controlled networks.
     This document complements RFC8281 by addressing the requirements 
     for remote-initiated GMPLS LSPs.  

      
     Conventions used in this document 

     The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", 
     "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in

     [RFC2119].
