The Mininet based "simulator", Mini-NDN, is actually an emulator in the sense that it runs actual instances of NFD and NLSR on each node provided by Mininet. As a result it does not scale very well due to CPU requirements. ndnSIM is a simulator based on NS-3
and scales much better.</div>

Just want to clarify: perhaps it’s better to say that the above statement about scalability is at best speculation because we haven’t done a comparison between the two under the same conditions yet. We have run Mini-NDN with 99 nodes (all running NLSR, NFD,
and every node ndn-ping’ing every other node) on one machine with a 2.7Ghz Intel Xeon E5-2680 CPU and 160GB memory. Currently we are exploring the MiniNet cluster edition to further scale up the Mini-NDN experiments.</div>

But Mini-NDN emulations might be more closer to real scenario. Running an NFD based application requires no modification in Mini-NDN, it might require some in ndnSIM.</div>

In Mini-NDN the user can interact with the running topology. Example query nfd-status of a node.</div>

<div class="PlainText">Good morning, thank you for the acceptance in the mailing list. I am a<br class="">
student and I am writing this mail in order to clarify some doubts<br class="">
about "how start".<br class="">
The documentation is a lot and I am a little lost.<br class="">
<br class="">
1) First of all, I noticed that there are two simulators: one Mininet<br class="">
based and then ndnSIM. I started some simulations with this last one,<br class="">
but I did not understand why there are two simulators: do they have<br class="">
different purposes?<br class="">
<br class="">
2) Always about ndnSIM, I am a bit in difficult. I successfully<br class="">
launched a simulation, the simple simulation scenario, but I have<br class="">
totally not clear how to:<br class="">
- Modifying the existing scenario<br class="">
- Make my own scenario. Should I utilize the Helper classes?<br class="">
- During a simulation in visual mode, I manage to look at FIB, PID and<br class="">
CS. But I am not able to do the same launching the program in console<br class="">
with gdb.<br class="">
<br class="">
3) Finally, the cpp library. I saw it, but I do not understand, again,<br class="">
how to start. I saw the example about Consumer and Producer, but if I<br class="">
would like to build a network with some producers, some consumers, and<br class="">
some gateways! Should I utilize the NFD daemon or is it totally a part?<br class="">
<br class="">
Excuse-me for the noob questions,<br class="">
Thanks a lot<br class="">
Matteo<br class="">
