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.
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

for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
