25/**
26 * This scenario simulates a very simple network topology:
27 *
28 *
29 *
30 * ----------------------------- (Producer)
31 * / |
32 * / |
33 * (Consumer) ------ (Non-Producer-Region Router) ----- (Produer-Region-Network Router)
34 * |
35 * |
36 * ( )
37 *
38 *
39 *
40 *
41 * Consumer sends interest with Link object attatched. Non-Producer-Region Router will
42 * forward the interest based on Forwarding Hint(dalegationName in Link object) toward
43 * delegationName direction because the router is not in
44 * ProducerRegion. Producer-Region-Network checks incomming interests and finds out the
45 * interest has reached ProducerRegion, thus the router will forward the incoming interest
46 * based on interestName.
47 *
48 * For every received interest, producer replies with a data packet, containing 1024 bytes
49 * of virtual payload.
50 *
51 * To run scenario and see what is happening, use the following command:
52 *
53 * NS_LOG=nfd.Forwarder=logic ./waf --run=ndn-simple-for-nrt-helper
