Continuation Week 03
This is the third of a set of week-long continuation runs. It's similar to Week 02, but drops Washington MyPLC (which had been unreliable recently) and adds Utah ProtoGENI.
The hostpair tables list hostnames when they're short, or SSH aliases (from my ~/.ssh/config file) when they're not. The ssh config aliases are in the log directory below.
There was an outage during this run when the system where I run my OpenFlow controllers needed to be rebooted for OS updates. The iperf clients in the SteadyPerf TCP slices (plastic-103 - plastic-106) all either died or hung as a result, and had to be restarted, which is why there are two sets of results for each of them.
The raw logs are at http://www.gpolab.bbn.com/plastic-slices/continuation/weekly-03/.

The Fedora 12 iperf client (at Clemson and Stanford) sometimes reports nonsensical bandwidth results if the client dies or hangs.
Very low bandwidth from GT -> Utah; much lower than any of the others.

Comments
There was an outage during this run when the system where I run my OpenFlow controllers needed to be rebooted for OS updates. The iperf clients all either died or hung as a result, and had to be restarted, which is why there are two sets of results for each of them.
The Fedora 12 iperf client (at Clemson and Stanford) sometimes reports nonsensical bandwidth results if the client dies or hangs.
Very low bandwidth from GT -> BBN, although not as much lower as in some of the other slices.

GT -> Clemson was not low at all, which is interesting, in that it perhaps suggests that the problem isn't strictly at GT.
