This question has been asked four times on NDN/CCNx mailing lists. Please
read the archives.
I’ve put this into NFD wiki “user knowledge” just now.
Then I have a question about how NDN communicates with upper and lower

The library tells the application what’s the size limit including all
ndn::MAX_NDN_PACKET_SIZE in ndn-cxx.
Is there a layer between NDN and the application that is in charge to

Yes, the transport layer does that.
