Abstract:
   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 Path Computation Element
   Communication Protocol (PCEP) extensions when a PCE-based controller
   is also responsible for configuring the forwarding actions on the
   routers, in addition to computing the paths for packet flows in a
   segment routing (SR) network and telling the edge routers what
   instructions to attach to packets as they enter the network.  PCECC
   as defined in RFC 9050 is further enhanced for SR-MPLS SID (Segment
   Identifier) allocation and distribution.
