Ok, thank you very much

OK, I don't think that you can interact with the mininet controller, or let's say I don't think it makes a lot of sense. I don't whether this is meaningful or no (I am not the MiniNDN expert), but you could get information about connectivity from the "net" object in MiniNDN. You could create a controller class that observes connectivity, and whenever something changes, the controller can change the forwarding behavior of individual nodes using "nfdc". The implementation of that shouldn't be a big deal.

Thanks,
Philipp

I need the controller for the centralized routing my objective is to implement a routing protocol (existing or developed ) in the controller to test the centralized routing that's why I need the controller.
One suggestion is to look at mininet examples for controller and integrat it with mini-ndn examples it is possible?
Thank you phillip

I think your terminology is referring to MiniNet. In MiniNDN, we do not differentiate between controllers, switches and hosts - in MiniNDN we only have one type of nodes, which is "node".

What do you need the controller and the switches for? In MiniNDN you can directly configure all routing/forwarding information in the MiniNDN scenario, as far as I know, there's no need for a controller.

Not sure if you already have found the MiniNDN guide: https://minindn.memphis.edu/. Maybe have a look at the samples.

Thanks,
Philipp

Thank you for your reply in the first place I want to implement for example to implement a topology with 1 controller 2 switch and 3 hosts my first question is it possible to implement a controller in mini-ndn as mininet and if yes how to do it?

Thank you phillip

Hi Yassine,

thanks for reaching out.

I am not completely sure if I understood your question correctly. Do you want to use an existing routing protocol in your topology, or do you want to develop a new routing protocol?

In case you want to use an existing routing protocol you have two possibilities:

i) Use NLSR. Therefore, you need to install NLSR on every node of your topology. Thereafter, nodes can advertise the routes they are serving using nlsrc, and thats it. You can find an example here: https://github.com/phylib/dnl-experiment/blob/d55a8931ac457e47d68b5799ccb26209ffef843f/experiment.py#L98-L105

ii) Use the static routing helper: That's not a routing protocol, but helps you to install all the routes you need for your experiment. See this example: https://github.com/phylib/dnl-experiment/blob/9049629301984b82e7f5ee21800f74a471fb8b65/experiment.py#L91-L95

If you want to develop you own routing protocol, you need to develop your routing protocol and create a mini-ndn app when you want to use it in mini-ndn. Similar as done for NLSR (here: https://github.com/named-data/mini-ndn/blob/master/minindn/apps/nlsr.py). When you want to use it, you should be able to do it similarly as when using NLSR.

I am neither a routing nor Mini-NDN expert. That's why I copied you to the Mini-NDN mailing list (https://www.lists.cs.ucla.edu/mailman/listinfo/mini-ndn). Hope that people with more MiniNDN and routing experience can help out.

I hope that things got little clearer. In case anything is unclear, feel free to drop me a message.

Thanks,
Philipp

hello m.phillip
I am phd student and I work on the routing ndn i wonder how can I use a controller in mini-ndn topology and if is a way to implement a routing protocol on the controller.

thank you
