Dear All, We have just updated draft-chen-pce-sr-policy-ifit and renamed to draft-chen-pce-pcep-ifit. The draft has deeply changed because, as discussed in mailing list, the PCEP extension is now applied as TLVs to the LSP Attributes and not to the Association Groups. In addition, the PCEP extensions for IFIT are now general and the LSPA TLVs are applicable for all path types, of course if the IFIT methods (IOAM and Alternate Marking) are supported by the data plane. So the application to SR policy is now mentioned as use case.
Feedbacks and suggestions are always welcome.

Name: draft-chen-pce-pcep-ifit Revision: 00 Title: Path Computation Element Communication Protocol (PCEP) Extensions to Enable IFIT Document date: 2020-08-28 Group: Individual Submission Pages: 17 URL: https://www.ietf.org/internet-drafts/draft-chen-pce-pcep-ifit-00.txt Status: https://datatracker.ietf.org/doc/draft-chen-pce-pcep-ifit/ Htmlized: https://tools.ietf.org/html/draft-chen-pce-pcep-ifit-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-chen-pce-pcep-ifit Abstract: This document defines PCEP extensions to distribute In-situ Flow Information Telemetry (IFIT) information. So that IFIT behavior can be enabled automatically when the path is instantiated. In-situ Flow Information Telemetry (IFIT) refers to network OAM data plane on-path telemetry techniques, in particular the most popular are In-situ OAM (IOAM) and Alternate Marking. The IFIT attributes here described can be generalized for all path types but the application to Segment Routing (SR) is considered in this document. The SR policy is a set of candidate SR paths consisting of one or more segment lists and necessary path attributes. It enables instantiation of an ordered list of segments with a specific intent for traffic steering. 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.
