Eric,

Do you mean PING with multicast and broadcast? Please elaborate.


Yes. I'm not sure it's fully specified



The case for ATTACH is demonstrated in section 11.

I don't see that. Afaict all the examples in s 11 are compatible with tls. Which one do you think is not?

I had thought we got rid of those since they are underapecified. If not we should.

Hi,

For the base draft, at least two messages are sent without TLS/ DTLS: ATTACH and PING (multi-cast or broadcast use case). The two diagrams in section 1.2 should reflect these two usages.

Also, to be clear and explicit, the overlay link layer should depict the frame header and its relation to TLS/DTLS. I suggest the following:

      -------------------------------------- Overlay Link API
         +------+  +------+  +------+
         |<none>|  |TLS   |  |DTLS  |  ...
         +------+  +------+  +------+
         +---------------------------------+
         |      Framing Header             |
         +---------------------------------+

The <none> box accounts for the ATTACH and PING without TLS/DTLS.

Thanks

--Michael
