Continuation Week 01

This is the first of a set of week-long continuation runs. Some changes from previous continuation rounds:

  • We're down to six sites, because MyPLC at Wisconsin is no longer available.
  • We're now using all six sites in all ten slices, balanced to have traffic flowing somewhat evenly between each pair of sites.
  • The SteadyPerf UDP slices are now running at different rates: 2, 3, 4, and 5 Mb/sec per hostpair, so approximately 12, 18, 24, and 30 Mb/sec total in those four slices.

The raw logs are at http://www.gpolab.bbn.com/plastic-slices/continuation/weekly-01/.

Comments

Due to the change in how we log SteadyPing results, we can't easily tell whether the packet loss was all at once (e.g. during an outage of some sort), or steady throughout the experiment.

The clients on planetlab4.clemson.edu and pl5.myplc.grnoc.iu.edu (connecting to Clemson) died partway through, and had to be restarted.

Bandwidth varied substantially between the hostpairs. We haven't yet analyzed the results of the four SteadyPerf TCP experients to look for trends.

Comments

The client on pl02.cs.washington.edu (connecting to Clemson) died partway through, and had to be restarted.

Bandwidth varied substantially between the hostpairs. We haven't yet analyzed the results of the four SteadyPerf TCP experients to look for trends.

We haven't yet analyzed whether the packet loss wass all at once (e.g. during an outage of some sort), or steady throughout the experiment.

SteadyPerf UDP, using port=5110, time=518400, rate=5, and this table of client/server pairs:
