Path Computation Element Communication Protocol Extensions for MPLS-TE Label Switched Path Auto-Bandwidth Adjustment with Stateful PCE
RFC 8733, “Path Computation Element Communication Protocol Extensions for MPLS-TE Label Switched Path Auto-Bandwidth Adjustment with Stateful PCE”, is a Proposed Standard document published in February 2020 by D. Dhody, R. Gandhi, U. Palle, R. Singh, L. Fang. 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. Stateful PCE extensions allow stateful control of MPLS-TE Label Switched Paths (LSPs) using PCEP.
The auto-bandwidth feature allows automatic and dynamic adjustment of the TE LSP bandwidth reservation based on the volume of traffic flowing through the LSP. This document describes PCEP extensions for auto-bandwidth adjustment when employing an active stateful PCE for both PCE-initiated and PCC-initiated LSPs.
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.
