28/**
29 * This scenario simulates a very simple network topology:
30 *
31 *
32 * +----------+ 1Mbps +--------+ 1Mbps +----------+
33 * | consumer | <------------> | router | <------------> | producer |
34 * +----------+ 10ms +--------+ 10ms +----------+
35 *
36 *
37 * Consumer requests data from producer with frequency 10 interests per second
38 * (interests contain constantly increasing sequence number).
39 *
40 * For every received interest, producer replies with a data packet, containing
41 * 1024 bytes of virtual payload.
42 *
43 * To run scenario and see what is happening, use the following command:
44 *
45 * ./waf --run=ndn-simple-with-pit-count-stats
