* This scenario simulates a very simple network topology:
*
*
* +----------+ 100Mbps +--------+ 100Mbps +-------------------------+
* | consumer | <------------> | router | <------------> | producer (with 10k Apps)|
* +----------+ 1ms +--------+ 1ms +-------------------------+
*
*
* Consumer requests data from producer with frequency 10 interests per second
* (interests contain constantly increasing sequence number).
*
* 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=ndn.Consumer:ndn.Producer ./waf --run=ndn-simple
