Hi WG, We just uploaded a new draft defining the extensions to PCEP for the usage of the Path Residual Bandwdith. Please see the abstract below. Thanks Francesco, Young, Daniele -----Original Message----- From: internet-drafts@ietf.org [mailto:internet-drafts@ietf.org] Sent: venerdì 12 maggio 2017 17:26 To: Francesco Lazzeri <francesco.lazzeri@ericsson.com>; Daniele Ceccarelli <daniele.ceccarelli@ericsson.com>; Young Lee <leeyoung@huawei.com> Subject: New Version Notification for draft-lazzeri-pce-residual-bw-00.txt A new version of I-D, draft-lazzeri-pce-residual-bw-00.txt has been successfully submitted by Daniele Ceccarelli and posted to the IETF repository. Name: draft-lazzeri-pce-residual-bw Revision: 00 Title: Extensions to the Path Computation Element Protocol (PCEP) for residual path bandwidth support Document date: 2017-05-12 Group: Individual Submission Pages: 16 URL: https://www.ietf.org/internet-drafts/draft-lazzeri-pce-residual-bw-00.txt Status: https://datatracker.ietf.org/doc/draft-lazzeri-pce-residual-bw/ Htmlized: https://tools.ietf.org/html/draft-lazzeri-pce-residual-bw-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-lazzeri-pce-residual-bw-00 Abstract: The ability of a hierarchy of PCEs to compute accurate end-to-end paths across multiple domains is recognized as an important requirement in many applications. This document describes extensions to the PCE Communication Protocol (PCEP) in order to provide new path-related bandwidth metrics, which a PCC, like a H-PCE (either stateful or stateless), can use from an erstwhile path computation to deploy multiple LSPs (having the same end-points and constraints) without additional requests, until either the remaining bandwidth along that path is all allocated or a deployment fails. This information would also be beneficial for implementing abstractions of the domain topology, building the abstract connectivity incrementally, based only on really used constraints, as soon as path computation results are returned. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
