[ndnSIM] NDN FIB

[Alex Afanasyev]

Hi Joao,

What I meant is that the code (and simulations that we did originally) did not involve much dynamics with FIB. There is nothing against dynamics.

The only potential drawback is that there is no implementation of the specialized face/FIB interface (e.g., there is no ccndc-like command that can configure routes), but you either can use FIB methods directly (recommended) or via ndn::StackHelper (I would not really recommend this way, but it is possible).  Ideally, we should add some protocol to ndnSIM, similar (not necessary the same as) CCNx face management and registration protocol (http://www.ccnx.org/releases/latest/doc/technical/Registration.html).
