   The Path Computation Element (PCE) is a core component of Software-
   Defined Networking (SDN) systems.

   A PCE-based Central Controller (PCECC) can simplify the processing of
   a distributed control plane by blending it with elements of SDN and
   without necessarily completely replacing it.  Thus, the LSP can be
   calculated/set up/initiated and the label forwarding entries can also
   be downloaded through a centralized PCE server to each network device
   along the path, while leveraging the existing PCE technologies as
   much as possible.

   This document specifies the procedures and PCEP extensions for using
   the PCE as the central controller for provisioning labels along the
   path of the static LSP.
