BitTorrent client written in Python.

Terms:

• Queue size: All traffic processed by the system is in the form of network packets.

• Pieces: BitTorrent splits the file up into chunks called pieces, each of a certain size. Sometimes it's 256KB, sometimes it's 1MB. As each peer receives a piece, they become a seed of that piece for other peers. With BitTorrent, we do not have a single source to download from.

Installation:

$ pip3 install -r requirements.txt

Usage is as follows:

$ python3 client.py <filename>

##Example usage: Assuming there is a file named file.torrent stored in a subfolder named torrents, usage would be like this:

$ python3 client.py torrents/file.torrent

Client create a Downloads folder within its working directory to store all torrent downloads. Each torrent file will receive its own folder within Downloads named the same thing as the main torrent filename.

• Up to 30 peers at once (as recommended by the BitTorrent specification)
• Multifile downloads
• Pausing and resuming of downloads (it creates a temporary status.txt file during download that is uses to check progress if the download is halted for any reason)
• HTTP and UDP trackers
