Re: [ippm] Request for WG adoption

[Tommy Pauly <[e-mail]>]

Hi Haoyu,

Thanks for bringing this up again. As we’ve discussed in several previous meetings, this seems to be mainly a high-level description of work that is already concrete in IOAM, DEX, etc. As such, I am inclined to say that its content should be in other drafts (as has been done).

Any adoption call would need to be predicated on more list discussion of the content.

Best,
Tommy

For example, the PBT based on packet marking has been applied in “draft-ietf-6man-spring-srv6-oam” (https://datatracker.ietf.org/doc/html/draft-ietf-6man-spring-srv6-oam <https://datatracker.ietf.org/doc/html/draft-ietf-6man-spring-srv6-oam>) which I believe has passed the last call, but the detailed mechanisms such as configuration, data format, and export method are not covered there. Given the technique is equally applicable to other types of networks, we believe it’s necessary to have a  document to formalized the method.

One was latter stripped off to form an independent draft, IOAM DEX, which has been adopted by IPPM. The remaining one, PBT based on packet marking, is the core of the current draft. Thanks for the numerous discussions and feedbacks from the WG, we now have a draft with focused direction and relatively mature content.
