Hi,

I support adoption of this document by the IPPM WG.

Some comments/questions below, apologies if there’s any dead horses In there (I haven’t followed discussions on this document recently).

  1.  There are no config false nodes, is this on purpose? I believe operational data would be of use.
  2.  Some groupings are used only once, e.g. ioam-admin-config, ioam-filter. Don’t see the need for these groupings.
  3.  How is flow-id defined? Since it’s just a uint32 in the YANG, maybe add some text or reference if applicable?
  4.  Use unit statements where applicable, e.g. max-length
  5.  References would make it easier for readers/reviewers, espcially those who are not IOAM experts. e.g. for action-encapsulate or action-transit mean
  6.  Examples would be of great help to understand how the YANG moduel is to be used
  7.  Why is proof-of-transit  YANG defined in SFC? I understand how SFC makes use of POT, but couldn’t we use POT without SFC? It seems odd that a YANG module for a “protocol” would depend on an application making use of that “protocol”.

Regards,
Reshad.

Subject: [ippm] Call for adoption: draft-zhou-ippm-ioam-yang

Hello IPPM,

This email starts a Working Group call for adoption for draft-zhou-ippm-ioam-yang. Now that our IOAM documents are mature and progressing, the chairs believe it is time to consider the YANG work officially.

The document can be found here:

https://tools.ietf.org/html/draft-zhou-ippm-ioam-yang-08

Please provide your feedback on these document, and state whether or not you believe the IPPM WG should adopt this work by replying to this email. Please provide your feedback by the start of the IETF 109 meeting week, on Monday, November 16.

Best,
Tommy & Ian
