The IESG has approved the following document: - 'PCEP Extensions for MPLS-TE LSP Automatic Bandwidth Adjustment with Stateful PCE' (draft-ietf-pce-stateful-pce-auto-bandwidth-12.txt) as Proposed Standard This document is the product of the Path Computation Element Working Group. The IESG contact persons are Alvaro Retana, Martin Vigoureux and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-pce-stateful-pce-auto-bandwidth/ Technical Summary The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests. The Stateful PCE extensions allow stateful control of Multi-Protocol Label Switching (MPLS) Traffic Engineering Label Switched Paths (TE LSPs) using PCEP. The automatic 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 automatic bandwidth adjustment when employing an Active Stateful PCE for both PCE-Initiated and PCC-Initiated LSPs. Working Group Summary There was nothing unusual in the working group processing of this document. Before the document was adopted there were concerns regarding scaling and scope of the work. The version of this I-D that was adopted handled these and had broad support from the WG at the time of adoption and later during WGLC. There is consensus in the WG to publish this work. Document Quality The authors report "a few" implementations supporting this feature. Some, they say, are more complete than others. A few people in the working group performed substantial reviews, but most of the working group was quiet. During working group last call a good number of people reported that they had read the document and supported publication. Personnel Who is the Document Shepherd for this document?
