[ndnSIM] Incoming interest in producer node

[Spyridon (Spyros) Mastorakis]

Hi,

please forward your emails to the list, so that they are visible to all the subscribers.

This decision is related to 2 factors:

1) The producer application adds a route with cost 0 for the served prefix towards its local face:

https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-producer.cpp#L82 <https://github.com/named-data-ndnSIM/ndnSIM/blob/master/apps/ndn-producer.cpp#L82>

2) Once this route is added, the resulting outgoing face of a FIB lookup will be the one registered by the app. Interests with the registered prefix will be forwarded through the app face:

https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.5.0-30-g934f505-ndnSIM/daemon/fw/forwarder.cpp#L258 <https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.5.0-30-g934f505-ndnSIM/daemon/fw/forwarder.cpp#L258>

Hope that this helps,
