* +----------+ 100Mbps +--------+ 100Mbps +-------------------------+
|
|
* | consumer | <------------> | router | <------------> | producer (with 10k Apps)|

|
* 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.
