+ *                             ----------------------------- (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
