Re: [Lime] LIME OAM Yang Model Applicability

[Gregory Mirsky <[e-mail]>]

Dear All,
I haven’t seen any discussion after the invitation from LIME WG chairs. Earlier I’ve sent my comments to authors of the applicability draft and, I understand, they are working on the update. Perhaps it would be more productive if we start our discussion of the new, updated version of the applicability document.

                Regards,
                                Greg

Subject: LIME OAM Yang Model Applicability

Hi, All,

I am starting this thread, based on a discussion during the LIME meeting in Prague and subsequent action item.

LIME (https://datatracker.ietf.org/wg/lime) has a deliverable as follows:
- Applicability document: The YANG model(s) specified in this working group must be usable and extensible by the existing OAM technologies. This usability and extensibility must be demonstrated, for example with IP Ping, traceroute, BFD, and LSP Ping. Note the technology-specific data model extensions should ideally be worked on in the respective working groups.
which basically builds a working dependency on efforts that are building protocol-based OAM YANG models.
Based on this, I am copying the authors of the following 5 documents, and the chairs of the target WGs:

  1.  LIME Applicability http://datatracker.ietf.org/doc/draft-zhuang-lime-yang-oam-model-applicability
  2.  LIME YANG Model http://datatracker.ietf.org/doc/draft-tissa-lime-yang-oam-model
  3.  MPLS http://datatracker.ietf.org/doc/draft-zhang-mpls-tp-yang-oam
  4.  MPLS http://datatracker.ietf.org/doc/draft-zheng-mpls-lsp-ping-yang-cfg
  5.  BFD http://datatracker.ietf.org/doc/draft-zheng-bfd-yang
The main goal of this note is to explicitly connect all these streams of work, and ensure there is coherence and alignment. As LIME defines a protocol-independent YANG model (1), the Applicability document (2) should show how the model can be used, extended, and augmented to realize protocol-specific ones (3) (4) (5).

We would be happy to help facilitate this dialogue, which BTW can take the shape of an informal meeting or a virtual interim (thinking aloud) before next IETF.

Discuss!!! :-)
