Here are the details of Baseline 3, divided by slice.
In this baseline, we ran six rounds of experiments, one per day; except that too many things were down on the second day, so we ran two on the last day. In rounds 1 through 5, we ran all ten experiments simultaneously; in round 6, we ran them sequentially.
The Stanford FlowVisor was suffering from significant instabilities during this baseline. We were originally planning to use of-planet3.stanford.edu and of-planet4.stanford.edu in three experiments, but those plnodes were VMs, and were frequently unreachable. We switched to using of-planet1 and ofplanet2, which are on dedicated hardware, for round 1, but the FlowVisor problems also left them unreachable too much of the time, so we dropped the Stanford plnodes from this baseline entirely for rounds 2 - 6. The tables of client/server pairs are for rounds 2 - 6.

Analysis
Many things were down here: Clemson couldn't ping GT, GT couldn't ping Indiana, Indiana couldn't ping Rutgers, Rutgers couldn't ping Stanford. Stanford could ping Washington, but with noticeable packet loss. Similarly, washington could ping Wisconsin, with substantial packet loss. And Wisconsin to BBN also showed noticeable packet loss. Only BBN - Clemson worked as expected.

Analysis
Clemson to Wisconsin has no Server Report section, but looking at the server-side log (not quoted here), it looks like the expected amount of data was actually transfered. Wisconsin to GT looks good. GT to Clemson is also good, except that it ran for nearly half an hour due to a bug in the version of iperf that comes with Fedora 8, which causes it not to exit when run as a UDP client.

Analysis
Washington to Clemson failed because Clemson didn't actually have the file to serve, so it quickly sent twenty zero-length files. Clemson to Stanford just failed. Stanford to Wisconsin died partway through the first transfer. Wisconsin to BBN worked fine, but we didn't capture the du and md5sum output, so we've listed the transfer log here.
