Hello Marco,

I am not sure that I understand your exact goal (as the NotifyNewAggregate performs more than one things..), but I will try to elaborate on this a little bit. In ndnSIM 2.0, the forwarding is performed by NFD. Each forwarding instance (class Forwarder) has various attributes. One of them is the so called “StrategyChoice”. This is actually a table where the forwarding strategy per name prefix is stored. Using the API of the StrategyChoice class, you can find the forwarding strategy for each name prefix as it is installed on each node.

For the attributes of the “Forwarder” class, you can take a look here:


For the “StrategyChoice” class and its “findEffectingStrategy” method, you can take a look here:


Hope that this helps.
