Path Computation Element Communication Protocol Extensions for PCE-Initiated LSP Setup in a Stateful PCE Model
RFC 8281, “Path Computation Element Communication Protocol Extensions for PCE-Initiated LSP Setup in a Stateful PCE Model”, is a Proposed Standard document published in December 2017 by E. Crabbe, I. Minei, S. Sivabalan, R. Varga. It has since been updated by RFC 9756. The canonical text is published by the RFC Editor.
Abstract
The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Client (PCC) requests.
The extensions for stateful PCE provide active control of Multiprotocol Label Switching (MPLS) Traffic Engineering Label Switched Paths (TE LSPs) via PCEP, for a model where the PCC delegates control over one or more locally configured LSPs to the PCE. This document describes the creation and deletion of PCE-initiated LSPs under the stateful PCE model.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
