+ * ( ) ------ ( ) ----- ( )
+ * | | |

+ *
+ * Grid size could be specified using --nGrid parameter (default 3)
+ *
+ * All links are 1Mbps with propagation 10ms delay.
+ *
+ * FIB is populated using NdnGlobalRoutingHelper.
+ *
+ * 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.
+ *
+ * Simulation time is 20 seconds, unless --finish parameter is specified
+ *
+ * To run scenario and see what is happening, use the following command:
