virtual |
Virtual method to perform Interest propagation according to the forwarding strategy logic.
In most cases, this is the call that needs to be implemented/re-implemented in order to perform forwarding of Interests according to the desired logic.
There is also PropagateInterest method (generally, do not require to be overriden) which performs general tasks (adding face to the list of incoming face, updating PIT entry lifetime, calling DoPropagateInterest, as well as perform retransmissions (enabled by default).
| inFace | incoming face |
| interest | Interest packet |
| pitEntry | reference to PIT entry (reference to corresponding FIB entry inside) |
Reimplemented from ns3::ndn::fw::GreenYellowRed.
