32/**
33 * This scenario simulates a very simple network topology:
34 *
35 *
36 * +----------+ 1Mbps +--------+ 1Mbps +----------+
37 * | consumer | <------------> | router | <------------> | producer |
38 * +----------+ 10ms +--------+ 10ms +----------+
39 *
40 *
41 * Consumer requests data from producer with frequency 10 interests per second
42 * (interests contain constantly increasing sequence number).
43 *
44 * For every received interest, producer replies with a data packet, containing
45 * 1024 bytes of virtual payload.
46 *
47 * To run scenario and see what is happening, use the following command:
48 *
49 * NS_LOG=ndn.Consumer:ndn.Producer ./waf --run=ndn-simple
