     Internet-Draft  draft-ietf-pce-remote-initiated-gmpls-lsp-04.txt

     Abstract 

     Draft [I-D. draft-ietf-pce-pce-initiated-lsp] 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 [I-D. 
     draft-ietf-pce-pce-initiated-lsp] 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 
     this document are to be interpreted as described in RFC 2119 
     [RFC2119].
