Continuation Round 1

In this round, I ran plastic-104 over the weekend as a simple test that anything at all was working.

The raw logs are at http://www.gpolab.bbn.com/plastic-slices/continuation/round-1/.

plastic-104

SteadyPerf UDP, using port=5104, time=518400, rate=3, and this table of client/server pairs:

client server server address
ganel.gpolab.bbn.com wings-openflow-2.wail.wisc.edu server=10.42.104.95
wings-openflow-3.wail.wisc.edu orbitplc2.orbit-lab.org server=10.42.104.112
orbitplc1.orbit-lab.org pl4.myplc.grnoc.iu.edu server=10.42.104.72
pl5.myplc.grnoc.iu.edu sardis.gpolab.bbn.com server=10.42.104.53

One-time prep commands run on each client and server

sudo yum -y install iperf

Commands run on each server

server=<ipaddr>
nice -n 19 iperf -u -B $server -p 5104 -s -i 1

Commands run on each client

server=<ipaddr>
nice -n 19 iperf -u -c $server -p 5104 -t 518400 -b 3M

Results

Generated with

subnet=104
for host in $(awk 'NR%2==1' ~/plastic-slices/logins/logins-plastic-$subnet.txt | sed -r -e 's/.+@//') ; do echo -e "$host:\n\n{{{" ; grep -A 10 -B 1 "Client connecting" pgenigpolabbbncom_plastic$subnet\@$host.log ; echo -e "}}}\n" ; done

and then edited slightly to remove artifacts (like control characters, my prompt, etc).

(This works because the summary of the results are in the client logs, and the clients are the odd-numbered lines in list of logins.)

Analysis

There appear to have been two gaps in the two pairs that include Wisconsin: One of about eight minutes, and one of about 43 minutes. The raw logs have more details.
