| 4 | We can also observe the affect of some load in the network to the chosen policies by running iperf while the experiment is running. |

| 9 | After running this modified experiment with |
| 10 | |
| 11 | {{{ |
| 12 | omf exec -C omf-expctl.yaml wmxtutor-dash.rb |
| 13 | }}} |
| 14 | |
| 15 | and pushing the data and log files to iRODs: |
| 16 | |
| 17 | {{{ |
| 18 | iarchive -e expID -c dash |
| 19 | }}} |
| 20 | |
| 21 | try creating the same plots as before from the new '''expID'''.sq3 file. |
| 22 | |

| 25 | Which policy do you observe to outperform the others with iperf load present in the network? |
| 26 | |
| 27 | You can also calculate these numbers directly by running SQL commands on the result database; try (using your own '''expID'''): |
| 28 | {{{ |
| 29 | sqlite3 /var/lib/oml2/expID.sq3 |
| 30 | }}} |

| 32 | Try running the experiment a few times. Do the results change between different experiment runs? By how much? |
