CRAWDAD snu/bittorrent

Dataset of BitTorrent traffic from Korea Telecom's mobile WiMAX network, collected in March 2010.

date/time of measurement start: 2010-03-15

date/time of measurement end: 2010-03-31

collection environment: We carry out the experiments by three laptops (Intel Core 2 Duo CPU and 2GB RAM), and three USB dongles embedded with mobile WiMAX modem (KWM-U1000 and its upgraded version KWM-U1800). Another desktop computer (AMD Triple-Core CPU and 2GB RAM) is used to measure the performance of an Ethernet host in campus network.

data collection methodology: To measure the behaviors of peers of P2P applications, we modify the open-source BitTorrent client, Vuze, to monitor its operations. We select only popular video contents (25 min episodes of a popular sitcom), which have at least 300 seeds; their file sizes range around 300-400 MB. We capture packet headers by WinDump, and analyze the traces by Wireshark and TCPTrace to monitor the P2P operations and measure the throughput, RTT and so on. The XRO7000 toolkit is used to observe the WiMAX link layer activities such as the handover controlling messages. We consider three mobility scenarios of WiMAX hosts: (1) static: A subscriber station (SS) is located inside university campus network, where a single base station (BS) and a few repeaters cover the entire campus area. The location of the SS is inside a building, which is about 800 meters away from the BS. (2) subway: We take subway line 4 in Seoul Metro, from Sadang station to Myeong-dong Station. Distance between two stations is about 12km and it takes about 20 minutes by subway train. There are total 10 subway stations on the route including the above two stations. Note that there is Han river (about 2 km wide) in-between. At every subway station, a single BS is deployed, and one or more repeaters are installed in a tunnel between adjacent BSs to enhance the radio signal. Therefore, handovers occur whenever a subway train moves from one station to another. (3) bus: We take bus 501 from Seoul National University to Seoul Railway Station. The distance of the bus route is about 11km and it takes about 30 minutes. (We avoid the rush hour.) For comparison, we also captured traces of downloads on a host connected to 100Mbps Ethernet on the campus network of Seoul University.

sanitization: In tcpdump captures, the payload was cut off by resampling with tcpreplay and tcpdump, and the header was anonymized by tcprewrite.
