 * Consumer requests data from producer with frequency 100 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:
