30 * This scenario simulates a very simple network topology:
31 *
32 * CSMA bus (1Mbps, 10ms)
33 * +--------------------------+--------------------------+
34 * | | |
35 *
36 * +----------+ +--------+ +----------+
37 * | consumer | | router | | producer |
38 * +----------+ +--------+ +----------+
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-csma
