     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", 
     this document are to be interpreted as described in RFC 2119
