URI Signing (Phil Sorber)
-------------------------
https://www.ietf.org/proceedings/99/slides/slides-99-cdni-draft-ietf-cdni-uri-signing-01.pdf

- 2 revs since last meeting (Berlin)
- Move to JWT complete. Merge of HAS support complete.
- Plan to merge 2 Pull Requests. After that ready for WGLC. Four thumbs up.
- Kevin: agreeing on going forward; will start shepherd review in parallel.

HTTPS delegation (Frederic Fieau)
---------------------------------
https://www.ietf.org/proceedings/99/slides/slides-99-cdni-draft-fieau-cdni-interfaces-https-delegation-02.pdf

- Update adding ACME * proposal, looking at CDNI Metadata for booth-strap phase.
- Next step: add sub-cert, oob, and possibly lurk support and discuss triggers.
- Sanjay Mishra: slide 2, typo START -> STAR.
- Kevin: sent some comments on the metadata objects to the list. Question, should sub-certs be combined with ACME, or is it own object.
- Emile Stephane: have a registry and different metadata sets for the different methods in the same draft for now.
- Sanjay: will add sub-cert details, based on current sub-cert draft

- Asking for adoption. Kevin, saying a bit premature. Want to see how next draft develops and how it relates to sub-certs and STAR progresses and their needs. Will start talking to AD about what is needed for re0charter.

Any Other Business
------------------
 Lijuan (Rachel) Chen, Huawei presenting Ideas on Access network CDNs
 https://www.ietf.org/proceedings/99/slides/slides-99-cdni-new-work-proposal-cdn-access-network-00.pdf

 - New Business Model for CDN SaaS (CDN Service Provider) vs [PaaS, IaaS] (Network Operator)

 - Sanjay: what are looking for CDNI WG to do?
   Rachel: Current CDNI interconnect between CDN service provider interconnect is not sufficient. Discuss how one can enlarge the marketspace/capabilities. New direction for CDNs and CDNI.

 - Emile: does your solution reuse existing CDNI interfaces?
   Rachel: Will consider existing interfaces, but first consider a business model innovation, then capabilities.

 - Michael Kreipl(?): are you trying to solve a business model problem with a technical solution?
   Rachel: Both. The story, needs to make sense. Then we can discuss solution.

 - Kevin: business models are not really our scope. If there are new technical requirements on CDNI then it can make sense. Please write a draft that explains how CDNI relates to the idea, and what gaps that exist. CDNI interfaces can be used for intra-CDN, but it is definitely out-of-scope of the charter and would require re-chartering.
   Rachel: The idea does not break/stray from CDNI, but looks for deeper integration.

 - Yue (Michael) Yin: we can submit a draft with use cases and problem statement. CDNI should focus on new technical questions, to see if we can expand the existing interfaces.
