Re: [Anima] Adoption call for draft-friel-anima-brski-cloud-04, ends April 20th 2021

Hi everybody,

I think adoption is appropriate. I do have a few comments towards the next version.

1) This model is rather different from the basic ANIMA model, which was designed for nodes that start out with nothing but an IPv6 address. As the draft says:

>> The assumption is that the pledge already has network connectivity prior to connecting to the cloud registrar. The pledge must have an IP address, must be able to make DNS queries, and must be able to send HTTP requests to the cloud registrar.

I think there should be some discussion right at the beginning of the Introduction about this fundamental difference. The reason that ACP and BRSKI use GRASP flooding for discovery is to avoid any dependency on DNS or the wider Internet. You could use the BRSKI and ACP mechanisms in a disconnected network fragment and build up connectivity from there. (For example, if the pledge hears no RA messages that give it DNS or Internet connectivity, one could invent a GRASP objective like "Connectivity" that could be used to find a router or RADIUS server willing to help.)

2) 

>>  1.2. Target Use Cases
>> 
>> Two high level use cases are documented here. There are more details provided in sections Section 4.1 and Section 4.2.

This is not easy to read. It really needs to summarise the two cases in a few words. Otherwise, most readers will immediately jump to the two sections, as I did. Proposal:

Two high level use cases are documented here (voucher request redirected to local registrar, or handled directly by cloud registrar). There are more details provided in sections Section 4.1 and Section 4.2.

3) Security Considerations is a very big [[ TODO ]]. I would prefer to see some content  in the WG draft as soon as possible.

The draft is clearly in scope of ANIMA charter and milestones. Giving the dependent BRSKI has passed the IESG evaluation, the chairs feel that it may be the right time to call the adoption.
