+// ===========================================================================
+//
+// This is similar to dce-iperf.cc where both nodes are ns-3 nodes,
+// but in this example, if the --emulation argument is set to true,
+// node 1 will be a Linux container.  See the HOWTO on the ns-3
+// wiki:  http://www.nsnam.org/wiki/HOWTO_use_CORE_to_test_ns-3_TCP
+//
+// the argument "--emulation" can be used to enable emulation
+// the argument "--clientNode" can be used to change the client
+// from node 0 to node 1
+//
+// The program runs for 30 seconds
+//
+//         node 0 (ns-3)                   node 1 (container)
