/**
* This scenario simulates a very simple network topology:
*
*
*
* ----------------------------- (Producer)
* / |
* / |
* (Consumer) ------ (Non-Producer-Region Router) ----- (Produer-Region-Network Router)
* |
* |
* ( )
*
*
*
*
* Consumer sends interest with Link object attatched. Non-Producer-Region Router will
* forward the interest based on Forwarding Hint(dalegationName in Link object) toward
* delegationName direction because the router is not in
* ProducerRegion. Producer-Region-Network checks incomming interests and finds out the
* interest has reached ProducerRegion, thus the router will forward the incoming interest
* based on interestName.
*
* For every received interest, producer replies with a data packet, containing 1024 bytes
* of virtual payload.
*
* To run scenario and see what is happening, use the following command:
*
* NS_LOG=nfd.Forwarder=logic ./waf --run=ndn-simple-for-nrt-helper
