[ndnSIM] Question about ndnSIM apps

Hi Yifeng,

Actual sending is happening in the base ndn::Consumer class (ndn-consumer.cc).  As this is an application, the only communication channel to/from l3 protocol is through application face and registered callback (actually, to send from app, you always need to use callback).

Wouldn't extension of the forwarding strategy be a better fit for your needs?  Inside the forwarding strategy you have full control to which faces you want to send messages.

I'm trying simulate something similar to hop by hop TCP, e.g. every node receives interests, buffers them and then sends them out with typical TCP fashion (AIMD). I'm looking at ndn-consumer-window.cc, specifically in ConsumerWindow::ScheduleNextPacket. I see a send event is scheduled, and Consumer::SendPacket is called, but where in SendPacket is the packet actually sent? Can I specify a face to send? Also when receiving interests, are the interests buffered somewhere?
