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.
