I find that each node in Mini-NDN manipulates a specific NFD configuration file. I believe the reason is that every node has its own forwarder.</p>

<div>- Yes, each node runs its own forwarder, has all the essential configuration required to run NFD, NLSR, and so on. MiniNDN is an emulator, it is much close and similar to running ndn in a real environment. You can pretty much do most of the things that
are possible in real environment. </div>

Currently, I am trying to create a network topology with 1000 nodes in Mininet. I plan to implement it with NDN network architecture. I installed NFD successfully and I was able to run it with the “nfd-start” command. However, after I run some NDN traffic,
I find the FIB of all nodes is the same, which means every node in Mininet connects to the same forwarder. I believe I am in the wrong way, could you please give me some suggestions about it?</p>
<p class="x_MsoNormal" style="margin-top: 0px; margin-bottom: 0px;margin-top:0px; margin-bottom:0px; margin:0in 0in 0.0001pt; font-size:11pt; font-family:Calibri,sans-serif">

</p>
<div>
<div>- Honestly, I don't understand what are you doing here. If you are using MiniNDN than you dont have to run nfd-start command to start NFD because minindn already does that for you. For example, if you run
<b>sudo python examples/mnndn.py </b>on the default topology, it will start a 4 node minindn environment. And similarly, you can do it for larger topologies. Please refer to the examples.</div>
<div><br>
</div>
<div>- Now, running 1000 nodes topologies definitely incur huge overheads, especially if you use NLSR. So, to tackle this problem and to scale minindn to larger topologies, we are developing
<b>ndn_routing_helper</b> modules. It computes routes from a give topology file and installs them in the FIB and so eliminates the use of NLSR. </div>

Besides, Mini-NDN is awesome! However, I believe I am unable to do the 1000 nodes experimentation with Mini-NDN due to its scalability.
