Here are the details of Baseline 1, divided by slice.
These results were copied and pasted from the terminal windows where the experiments were run; we didn't save full logs of those windows in this baseline.

Analysis
pl01.cs.washington.edu was unable to ping 10.42.101.96 (on wings-openflow-3.wail.wisc.edu) at all.
The other results seem consistent with what we'd expect.

99% packet loss suggests a lot of network congestion. We didn't attempt to discover where the congestion was (e.g. on the host interface, a switch between the host and the backbone, within the backbone, in the OpenFlow control path, etc).

Analysis
We used the wrong port for this slice by mistake, but think that this didn't cause any problems, since the traffic also uses to a unique IP address.
The other results seem consistent with what we'd expect.
