Re: [Lime] WG Adoption and IPR call for draft-kumar-lime-yang-connectionless-oam-05

Dear Authors, WG chairs, et. al,

I don't support adoption of the current version of the draft by the LIME WG. Below are my comments that may explain the reason for non-support:

·         the scope of the model isn’t clearly defined. The title suggests modeling OAM protocols that provide Fault Management (FM) and Performance Measurement (PM) in connectionless networks but the latter part seems absent in the proposed model. If only FM OAM is in the scope of this document, then I’d suggest updating the name of the draft;

·         the model uses references to the number of RFCs, e.g. RFC 5881,  within grouping tp-tools. If these are indication of OAM capability at a Test Point, then why is it rw as it seems to be more logical to be part of operational information, thus be ro;

·         the model still  refers to MPLS-TP even though WG agreed that MPLS-TP OM is an example of OAM for connection-oriented networks;

·         the model extensively refers to VPN cases, e.g. L3VPN, as example of connectionless network. I think that that yet has to be discussed as at the VPN layer network demonstrates characteristics of being connection-oriented;

·         the model does not reference, nor provides examples of use case of existing YANG data models of OAM protocols that are used in IP and IP/MPLS networks:

o   BFD (draft-ietf-bfd-yang);

o   LSP Ping (draft-zheng-mpls-lsp-ping-yang-cfg).

Perhaps another virtual interim meeting like one we had on May 27, 2016 would be helpful.

                Regards,

                                Greg

Subject: [Lime] WG Adoption and IPR call for draft-kumar-lime-yang-connectionless-oam-05

LIME,

This email starts the LIME WG Call for Adoption for draft-kumar-lime-yang-connectionless-oam-05.

https://datatracker.ietf.org/doc/draft-kumar-lime-yang-connectionless-oam/

It concurrently starts an IPR check on the same draft.  There’s currently no IPR disclosed.

Can I please ask the authors to reply-all to this email confirming whether or not they know of any IPR that needs to be disclosed? Additionally, for all WG participants, please also reply-all if you know of any IPR that needs to be disclosed.

As we discussed in Berlin, this document is in charter and targets one WG milestone. Please reply-all to this email indicating whether you support adoption of this document as basis for that deliverable, or if you have any concerns please detail those on the list.

The adoption call will close on August 23rd.

Thanks,

— Carlos & Ron.
