[Nfd-dev] [EXT] Installation of ndn components

[Junxiao Shi]

Hi Vazoumana

The named-data .net website is only minimally maintained, but GitHub
repositories do not lie.
In addition to https://github.com/named-data organization, there are some
NDN repositories under https://github.com/UCLA-IRL organization but those
are less mature.

For "simulation", you can consider doing emulation instead with Mini-NDN
codebase: https://github.com/named-data/mini-ndn
Mini-NDN itself is actively maintained, but a risk factor is that the
underlying Mininet codebase seems dead.
For now Mini-NDN developers have added enough patches so that it works on
Ubuntu 24.04, so that you can use it at least until 2029.
Mini-NDN currently uses NFD but there's ongoing effort to extend it to
ndnd's forwarder.
Development of Mini-NDN occurs in Gerrit
https://gerrit.named-data.net/q/project:mini-ndn+status:open , so you won't
see Pull Requests on GitHub.

Joining the testbed does not require you to setup anything.
You basically donate a machine and give testbed operators sudo access, and
they will do all the installation and management.
It benefits the ecosystem and gives you exposure, but does not benefit your
simulation work.

Yours, Junxiao
