Hello, I do not believe this document is ready for adoption. I believe the WG perhaps needs to discuss some basic concepts before taking up this work.
Please note that I do not object to (what I infer is) the motivation for this work. This document is not (yet) a good starting point for this work. 1) We need a SPRING WG document that covers the considerations related to Path MTU for SR Policies. We do not have such a document today. While this document does touch upon certain aspects, it is inadequate. This document should focus more on the PCEP protocol aspects and rely on the existing RSVP-TE spec RFC3209 and TBD for SR Policy for the application to the respective constructs. Note that draft-ietf-idr-sr-policy-path-mtu introduces this PMTU for BGP SRTE [*] 2) There seems to be some degree of mixup between the concept of (a) constraint for the path and (b) the reporting of the calculated path MTU of the path. Both are perhaps needed, but we need them to be unambiguous and differentiated. I would think that (a) is also very useful. And I am not sure if it is appropriate to refer to (b) as a "metric" - isn't it a property? 3) This is applicable for both RSVP-TE and SR Policy. [*] What I see is that some amount of uncoordinated protocol spec development related to SPRING constructs is happening in the protocol-specific WGs (PCE & IDR) without the base work being done in the SPRING WG. I had raised this point during the IDR document adoption as well: https://mailarchive.ietf.org/arch/msg/idr/ZrN1-Uw1ggyxKeltBICmcthjymM/ Thanks, Ketan On Mon, Mar 28, 2022 at 9:40 PM Dhruv Dhody <d...@dhruvdhody.com> wrote: > Hi WG, > > This email begins the WG adoption poll for draft-li-pce-pcep-pmtu-05. > > https://datatracker.ietf.org/doc/draft-li-pce-pcep-pmtu/ > > Should this draft be adopted by the PCE WG?
