[ndnSIM] NACKs in ndnSIM2.0?

[Spyridon (Spyros) Mastorakis]

Hello,

in ndnSIM 2.0, we use the NDN Forwarding Daemon (NFD). NFD does not currently support NACKs as data packets. However, it is a feature planned to be added in the future.

As soon as this feature is added in NFD, it is going to be supported by ndnSIM as well.

I have looked through the documents and API specification, however, I don't understand if and how the concept of "NACKs" is supported in ndnSIM2.0. Can someone give me a hint how to implement the following in ndnSIM2.0:

In ndnSIM1.0 I have used the build-in NACK-response from the NACK-Strategy, which responds with a NACK-message once all faces have been set to "waiting in vain".
