Re: Call for Adoption: Extensible Prioritization Scheme for HTTP

[Tommy Pauly <[e-mail]>]

Hello all,

Thanks for the feedback received in the call for adoption! We will be adopting this document into the working group. We have asked Lucas and Kazuho to continue as editors of the document.

Authors, please submit a draft-ietf-httpbis-priority-00 when ready; we'll also move this document into the WG GitHub.

As mentioned previously, this work is an important piece of deploying HTTP/3. As such, I would like to encourage that we try to converge on open design issues quickly (QUICly?). The adoption call did highlight that the main concern is around the use of headers or frames for signaling. If anyone has thoughts on this issue, please take them to the list and/or GitHub.

Best,
Tommy & Mark

Note that adoption indicates that we, as a working group, want to use draft-kazuho-httpbis-priority as a basis for the definition of priorities for HTTP/3. There is still ongoing discussion that will continue, specifically around the mechanism for end-to-end and hop-by-hop signaling.
