Introduction
|

|
|
============
|
||
|
|
|
||
|
|
This directory contains patches and scripts for my experiments regarding download time estimation
|
||
|
|
algorithms, using KTorrent for gathering data ;-)

Files
|
||
|
|
=====
|
||
|
|
|
||
|
|
enable-logging.diff - Patch to apply to enable logging download stats once per second to $KDEHOME/share/apps/ktorrent/log (by Ivan). Apply it if you want to help collecting test cases.
|
||
|
|
|
||
|
|
processlog.rb - extracts logs for single torrents from $KDEHOME/share/apps/ktorrent/log and stores them in $FILENAME-torrent.log
|
||
|
|
|
||
|
|
Sample.rb - class representing a sample, does the parsing (given a line from adjustTimestmaps output)
|
||
|
|
|
||
|
|
Estimators.rb - Some basic estimators, for estimation based on current speed, average speed and moving average speed.
|
||
|
|
|
||
|
|
EstimationResults.rb - Calculates and holds the estimation results of an estimator, including statistics such as relative error for each estimation, root mean square error and the like
|

What to do
|
||
|
|
==========
|
||
|
|
|
||
|
|
1) Apply the patch: In torrent/ dir, apply it via
|
||
|
|
|
||
|
|
cat enable-logging.diff | patch -p0
|
||
|
|
|
||
|
|
2) Run ktorrent and download torrents. When completed, run processlog.rb:
|
||
|
|
|
||
|
|
ruby processlog.rb $KDEHOME/share/apps/ktorrent/log
|
||
|
|
|
||
|
|
Extracted logs end up in $TORRENTFILENAME-torrent.log. ATTENTION: existing files are overwritten!
|
||
|
|
|
||
|
|
4) Now, analyze the -adjusted file with a ruby script, using Sample.rb, Estimators.rb, and EstimationResults.rb... ;-)
|
||
|
|
I will upload something useful as soon as finished.
