Hi Junxiao,
Thank you very much for your prompt response.

Yep. I know about this. Lixia told me that we can allocate some manpower
for it. We have developed our codebase, but it is far away from NDN
concepts totally. AFAIK, there is not any other codebase. That's why we
prefer to use the NDN-Lite codebase. If there is a more recent codebase, I
appreciate it if it is shared with us.(I got the answer below: NDND)

We chose Contiki NG OS because we have some know-how about it. We know it
is easily ported to POSIX (i.e. RIOT) At least, we want to give it a shot.
I am also curious if I can manage to integrate it for the NDNComm 2025
Hackathon.
We also plan to use it with RIOT.

Possibly, there will also be issues in the future versions. I question if
we can design a perfect one at all. We want to start from somewhere, and
NDN-Lite sounds like a good one and only candidate AFAIK. (I'll check NDND)
We planned to integrate NDN-Lite to Contiki OS because both are in C. There
might be ways to connect C and Go, but It will require more expertise I
assume.

I do not know about StateVectorSync. I'll check it. Thank you for
addressing me. Do you think that it is a MUST for NDNoT?;

We can consider these issues into our agenda. I need to find manpower for
them.

AFAIK, your "Sovereign: Self-Contained Smart Home With Data-Centric Network
and Security" uses NDN-Lite. As I see it, it was for a small-scale NDNoT
environment.

Thank you for sharing NDND with me. I did not know about it. I'll check it.
Lixia is giving me a lot of homeworks that I am trying to catch up with
(Just kidding.) It's good. I'm learning. I am doing my best to find
manpower. However, everyone is going after AI/ML/DL nowadays. I am trying
to make  AI+Network attractive as much as I can. People should understand
that AI+Network is a much more unexplored area. Another tech is Quantum.
Maybe we should put some Quantum Internet, Quantum NDN into our agenda. +
always security.

This information is invaluable to me.Definitely, I'll start learning about
it ASAP. Just a naive question: what are the differences between NDND
and NFD other than having different programming languages? Why NDND?

Thank you Junxiao
