* This scenario simulates a grid topology (using topology reader module)

* ( ) ------ ( ) -- (producer)
*
* 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.
*
* To run scenario and see what is happening, use the following command:

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