Hi,

I am also studying the GRASP objective definition recently.
I have one question: why does F_SYNCH_bits appear in the discovery process?

Best wishes,
Joanna

Hi,

One quick comment on the draft.

>       An example of discovery message using GRASP would be the following
>       (in this example, the fog monitoring controller is identified by
>       its IPv6 address: 2001:DB8:1111:2222:3333:4444:5555:6666):

>       [M_DISCOVERY, 13948745, h'20010db8111122223333444455556666',
>       ["FOGDOMAIN", F_SYNCH_bits, 2, "operator1"]]

If I can make a suggestion, I think it is better to start with an informal descrition and a CDDL definition of the GRASP objective. The details of the message don't really help the reader understand. 

Also I am not sure it needs multiple GRASP objectives. I think Toerless has a very good idea in his service description mechanism (draft-eckert-anima-grasp-dnssd), with JSON-like dictionaries that are very flexible, easily extensible, and trivial to map into CBOR. I don't think that changes the model, it just gives a lot more flexibility for the future. I think it would also make mapping to and from YANG based mechanisms a lot easier.
 
Regards
