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

A PCE as a 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 Label Switched
Path (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 for using the PCE as the
central controller for provisioning labels along the path of the
static LSP.

This document is a product of the Path Computation Element Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
