Abstract:
   The Path Computation Element (PCE) is a core component of Software-
   Defined Networking (SDN) systems.  It can compute optimal paths for
   traffic across a network and can also update the paths to reflect
   changes in the network or traffic demands.

   The PCE has been identified as an appropriate technology for the
   determination of the paths of point-to-multipoint (P2MP) TE Label
   Switched Paths (LSPs).

   PCE was developed to derive paths for MPLS P2MP LSPs, which are
   supplied to the head end (root) of the LSP using PCEP.  PCEP has been
   proposed as a control protocol to allow the PCE to be fully enabled
   as a central controller.

   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 P2MP 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 P2MP 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 P2MP TE LSP by provisioning
   labels along the path of the static P2MP LSP.
