+In this round, I ran plastic-104, plastic-105, and plastic-106, for about 24 hours, with a somewhat higher data rate for plastic-106.

+The raw logs are at http://www.gpolab.bbn.com/plastic-slices/continuation/round-3/.

+== Analysis ==
+
+A fair bit of variability in transfer speeds, correlating somewhat with latency. Wisconsin - Clemson only goes through two NLR switches (Chicago to Atlanta); Clemson - BBN follows the same path in the core, but has to go from Chicago all the way to Boston, so that makes sense. The results that include GT are harder to explain: BBN - GT is slower than BBN - Clemson, where you might expect it to be faster; and GT - Wisconsin is slowest of all, a factor of six worse than Wisconsin - Clemson. What's up there?

+With one exception, all data seems to have been sent successfully (up to four nines, anyway).
+
+The exception: GT - Wisconsin, which had 7.5% packet loss. Could this (which also included plnode1) be related to the poor results with plnode1 in plastic-105?
