This script is for reproducing Simbricks line in [Figure 1] DCTCP result.
 
We used following combination of simulators.
HOST: Gem5 timing CPU
NIC: Intel i40e behavioral model
NET: ns-3 dumbbell model

The simulation composed of two pairs of iperf server and client, connected 
in a dumbbell topology.
The link between two switches is the bottleneck link.

 [HOST_0]-[NIC_0]-----[SWITCH]---[SWITCH]-----[NIC_1]-[HOST_1]
  server_0                |        |                client_0
                          |        |
 [HOST_0]-[NIC_0]----------        ---------- [NIC_1]-[HOST_1]
   server_1                                          client_1

The command to run all the experiments is:
$: python3 run.py pyexps/ae/f1_dctcp.py --filter gt-ib-* --force --verbose
