The trace T8'09 was collected from unix-ag.uni-kl.de by scraping its tracker since 24 Sep 2009 with 5 minute sampling interval. This trace was collected by Dr. Iosup, and studied by Zhang and et al [1][2]. This community mainly distributes Knoppix linux distributions and only provides legal contents. This trace contains community level and swarm level data: community level data contains the number of leechers and seeders, total number of completed downloads, total traffic and average download progress of all participating peers of each swarm; peer level data contains peerís ip address with last byte blinded, port number, download amount, upload amount, connected time, sharing ratio, download progress, download speed and upload speed in each measured swarm. And both datasets contain descriptive information of torrents including file name, infohash, added time, file size and number of files in each torrent.  In 2009, until now 160,522 sessions in 12 swarms are measured and the daily throughput of this community is 348 GB.
