NDN has a request/reply model with symmetric forwarding. This means that an upstream network provides feedback to the downstream one. NDN has nothing to do with content delivery.

That RFC is like meeting at a Pink Floyd's concert. You meet three generations! And it's not done yet!

It is a very good remark to correlate John's comment about upstream/downstream information exchange and NDN. NDN can do that indeed. Have a look at this way to get NDN-like networks using IPv6 https://datatracker.ietf.org/doc/draft-muscariello-intarea-h... https://wiki.fd.io/view/cicn
