| 40 | * Consumer requests data from producer with frequency 10 interests per second |
| 41 | * (interests contain constantly increasing sequence number). |
| 42 | * |
| 43 | * For every received interest, producer replies with a data packet, containing |
| 44 | * 1024 bytes of virtual payload. |
| 45 | * |
| 46 | * To run scenario and see what is happening, use the following command: |

| 48 | * NS_LOG=ndn.Consumer:ndn.Producer ./waf --run=ndn-grid-topo-plugin |
