Continuation Round 8

In this round, the plan was to run all ten slices on all seven sites (down from eight, because MyPLC at Rutgers is no longer available), for a week.

However, MyPLC and Stanford and Washington also went down, and the slivers there were destroyed after four days. We ended the round at that point, and summarized the results for the hostpairs that don't include Stanford or Washington.

The raw logs are at http://www.gpolab.bbn.com/plastic-slices/continuation/round-8/.

Comments

The logs for most of the hostpairs were truncated, presumably because they were still being written to disk when the sliver was shut down. Handling the ping logs in this way is proving problematic, and will need to be revisited.

There was a blip at Clemson during the run, which might account for the nearly 1% packet loss. (Which isn't a *lot*, but is a little higher than expected.)

There was a blip at Clemson during the run, which might account for the nearly 1% packet loss there. (Which isn't a *lot*, but is a little higher than expected.)

Sending data from GT plnodes is known to have some issues, which probably accounts for the 1.6% packet loss there.

Comments

The raw log for GT had 2438 identical copies of the summary, I think because I accidentally reconnected to the screen session within the screen session at one point. I trimmed them down to the one shown above.

The bandwidth from GT to BBN is unusually low, even given the known issue with GT's plnodes.

Since pl02.cs.washington.edu was connected to of-planet2.stanford.edu, the server log at Stanford also doesn't have a summary of stats, although one could in theory be generated from the raw log.
