[ndnSIM] BestRoute2 and Nacks

[Spyridon (Spyros) Mastorakis]

Hi,

for the way that BestRoute2 works take a look at section 5.2.1 and for NACKs at section 4.4 of the NFD developer’s guide:

Firstly if i have multiple interfaces to reach a producer, how does it select a best route, based on hop count? When does it decide to switch this best interface to another interface? What affects the metric of selection of best interface.
