Continuation Round 7

In this round, we ran all ten slices, but only with five sites (BBN, Clemson, Rutgers, Stanford, and Wisconsin). The goal was to turn off static ARP, testing before and after to see if there were any significant differences, so the results are in two parts.

The raw logs are at ​http://www.gpolab.bbn.com/plastic-slices/continuation/round-7/ (with 'before' and 'after' subdirectories).

Results

Since we transfered the file to each client hundreds (if not thousands) of times, we didn't save all the copies, but we did generate an MD5 checksum after each download, and log that, so we ran some grep commands on the logs to count the number of total checksums printed in each log, and the number where the checksum had the expected value.
