Hi
Thanks for your feedback. This is the design before PAP Draft 02. I didn't
notice that there was a GRASP protocol.
Therefore, we submitted draft 03 and wanted to get the comments from ANIMA.
Whether the use cases and ideas mentioned in the PAP can be extended on the
GRASP.
Regards
Shuanglong

Hi,
I don't really understand why you might need a new protocol for this. It sounds
like a very good application for the ANIMA model, and everything you describe
could easily be expressed in GRASP objectives (synchronization or negotiation
are both covered). You discuss this in Section 7.
On one specific point:

I don't understand that argument. In either case you need a listener, whether
it's listening for a new TCP connection or a new UDP session. Actually it's a
lot more work, in my experience, to write a UDP server because it has to do a
lot of housekeeping that TCP does for you. I started designing a GRASP
implementation over UDP but decided that it would not in reality be more
efficient than TCP, because it would need extra logic at the upper layer to
manage session state.
Also of course TCP gives you TLS, which I suspect is a lot easier in practice
than DTLS. However, if you use the ANIMA infrastructure you get a full security
solution without any extra work.
