[ndnSIM] Need help (exactly which file sends interests)

[Spyridon (Spyros) Mastorakis]

Just a note on that:

in the latest ndnSIM paper we have published, there is a figure, where we present in detail the exchange process of an NDN packet between 2 simulated nodes. I am talking about figure 6 here:

Thanks,
