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

Thu Jul 24 11:19:32 PDT 2025

Installing Mininet itself on 24.04 LTS also has some issues with relying on outdated Python modules/behavior that had slipped my mind; I may look into seeing if the installation script can be patched in the short term. I would only recommend 22.04 LTS for now if you’re not confident about doing the work of solving these issues for now.

The installation of wireless simulation components on 24.04 LTS was having some issues as of a few months ago (certain dependencies we do not manage were not being maintained), so we’re only officially recommending 22.04 LTS at the moment; I need to recheck the status of the install with/without the wireless module to see if this was addressed. We’re also about to post a warning that Virtualbox is not currently recommended on Windows host systems for reproducibility reasons, we recommend using VMWare Workstation at the moment.

It’s worth noting Mini-NDN is a realtime emulator rather than a simulator, which entails some differences relative to ns3-style experiments. We have a mailing list linked in the README if you have any specific questions.

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

Hi Vazoumana

ndnSIM is unmaintained.
when i look onto website https://named-data.net/codebase/platform/ , it's not obvious. But , you're right. I will refer to github repositories activity.
It can be considered as a historic codebase that requires period-correct operating systems and compilers, e.g. Ubuntu 20.04.
For system security, you should not expose the operating system to the Internet:

  1.  Install ndnSIM in a virtual machine only.
  2.  Block all network connections into and out of the virtual machine.
  3.  Deploy an HTTP proxy so that the virtual machine can download packages.
Ok, i got it. According to me, it s important to have a simulation software. But i understand , it's required time, human an development effort  to maintain it.

NFD is only passively maintained.
While it is possible to install both ndnSIM and NFD in the system, this is not recommended due to vulnerabilities in Ubuntu 20.04.

Most of the recent innovations are in this codebase: https://github.com/named-data/ndnd
You should use ndnd for new deployments and experiments.
Ok, so with this version, it doesn't require to get standard library client. It's included, isn't it ?

Both ndnSIM and NFD are single-threaded for most workloads, so they need high clock rate processors.
ndnd is multi-threaded in most modes, so they can work with the typical server processors that have many cores of moderate clock rate.
Ok, i set up a vm with 20 cores. It will be enough to run comfortably ndnd.

Yours, Junxiao

Thanks. When i will finish set up ndnd node, i will look deeply and surely join testbed. Otherwise, i need to understantd more all mechanism and strategies chosen on ndn implementation.

Dear All,

I'm vazoumana fofana, network and system engeener in French laboratory.
As new user, i enjoy joining NDN community.

I have 2-3 questions :

- According to website, ndnsim seems to be not supported yet on
ubuntu24. Is it an ongoing task ?

- is there any inconvenients to install ndnsim and NDN chain ( NFD,
ndn-cxx) on same node ? is there any hardware requirements (RAM,
storage, CPU, cores) ?

- On mailman interface, i didn't see any field to fill in order to
search a string keyword. Maybe, i missed something.

Best regards.
