BitTorrent is a popular peer-to-peer file sharing protocol that accounts for approximately 44% of all P2P internet traffic. The document analyzes BitTorrent downloads using the Wireshark network protocol analyzer. Three files were downloaded using different BitTorrent clients and network conditions - a fast download from a seeded file, a typical download, and a slow download with few seeders. Network statistics like throughput, round trip time, and packet sequencing were captured and graphed for each download.

Why BitTorrent.. ?
Why BitTorrent..? P2P network architectures have become very popular BitTorrent traffic represents approximately 44% of all the P2P traffic on the internet
Why BitTorrent..? Traffic measurements show P2P traffic dominate the network bandwidth
BitTorrent -44% Incoming Traffic Outgoing Traffic BitTorrent -21%

Sample selection Have chosen three torrents Two of these, Downloaded on Home wireless network One of them downloaded on Clemson University wireless network (TigerNet).
Sample selection Sample 1 Vuze Sponsored Download ( one of the reason for choosing This as a client) Sample was a Video, the download was very fast as Vuze was seeding it
Sample 1
Sample selection Sample 2 This was a normal BitTorrent file downloaded from a popular torrent site “The Pirate Bay” It was a Linux distribution (Ubuntu)
Sample selection Sample 2
Sample selection Sample 3 This was a normal BitTorrent file downloaded from a popular torrent site “The Pirate Bay” Chosen a torrent which was unpopular, with not so many seeders Wanted to explore the characteristics of a slow download
Sample selection Sample 3
Download Speeds Sample 1 Average Download speed – 340 Kbps Sample 2 Average Download speed – 300 Kbps Sample 3 Average Download speed – 30 Kbps
Analysis Tool - WireShark WireShark is a packet sniffer application Similar in functionality to Tcpdump but has a graphical front-end and many more sorting and filtering options
Analysis Tool - WireShark Used Mac OsX 10.5 as the platform for performing the Trace analysis Captured the Trace using Wireshark Extracted the Trace Data containing only the BitTorrent Protocol from the raw traces
