28 * This scenario simulates a grid topology (using topology reader module)
29 *
30 * (consumer) -- ( ) ----- ( )
31 * | | |
32 * ( ) ------ ( ) ----- ( )
33 * | | |
34 * ( ) ------ ( ) -- (producer)
35 *
36 * All links are 1Mbps with propagation 10ms delay.
37 *
38 * FIB is populated using NdnGlobalRoutingHelper.
39 *
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:
47 *
48 * NS_LOG=ndn.Consumer:ndn.Producer ./waf --run=ndn-grid-topo-plugin
