Thanks for the update. I'm looking forward to the discussion in ACE.

Hi All
I have published the first draft for the document here is the link to the draft https://datatracker.ietf.org/doc/draft-msahni-ace-cmpv2-coap-transport/. As Jim mentioned that adopting this might need change in the ACE WG charter can we please discuss that in IETF 108 ?

Thanks
Mohit

Hi Jim,
Thanks for the feedback. I will go over the EST document and update sections around DTLS and proxying and address your other comments. Once ready, I will post the draft in ACE WG.

Regards,
Mohit

I suppose that this could go into the ACE working group, but it will require a charter change to do so.  
 
I would suggest that you review the EST document with special attention to the sections on DTLS and proxying.  It would also help to have some idea of guidance for when coap or coaps is going to be used.  I am not sure that this strongly exists in CMP as my very vague memory was that it was assumed that all transactions where going to be done over TLS with server validation as a minimum.

Hi Tomas
Thanks for the feedback, I was trying to write it in a way so that it can work for both CMPv2 and LightWeight CMP, I have noted it your feedback and I will try to make it more clear.

Hi,

I noticed that section 4, Proxy Support (good section btw), mentions
Announcement messages. These are excluded from the Lightweight
specification. Since the LIghtweight specification is mentioned in the
beginning, I'm not sure if that's worth mentioning here?

Cheers,
Tomas
