How much data is available on Bittorrent

Torrent


The term “torrent” (German: Sturzbach) is the short form of BitTorrent. This is a web protocol that is mainly used for file sharing, for the rapid exchange of large amounts of data over the web. The special thing about torrent technology is that every file transfer takes place via a single network of distributors and not via a central network.

History [edit]

In 2001, the programmer Bram Cohen developed the so-called BitTorrent protocol and introduced it in July of the same year. Originally, the technology was intended for its own online community. But the innovative technology of data exchange, even with slower Internet connections and low server load, has quickly established itself in the booming Internet. The principle of give and take and the free exchange of data with one another via the World Wide Web were in the foreground.

In just a few years, a separate scene of file sharers has established itself, who exchanged large amounts of data such as music, videos or PC games with one another. BitTorrent Inc., founded by Bram Cohen, operated one of the largest file-sharing networks in the world until 2007. But in the wake of growing criticism of the peer-to-peer networks in which copyrighted material was shared for free, the company switched its business to a paid model.

However, the actual torrent technology is still used around the world to exchange large amounts of data with one another. Numerous services and software still use the protocol.

Technology [edit]

With the help of torrents, large files can be downloaded quickly even on slow internet connections. This may also have been the reason for the inventor of BitTorrent, Bram Cohen, to develop this technology.

Bit torrent technology is based on the TCP / IP protocol and works like a P2P network. In contrast to conventional download methods, for which only the download capacities of the data source are used, BitTorrent also uses the download bandwidth of the so-called "seeder". This allows torrent files to be downloaded quickly by sharing them with multiple users on the network.

How it works [edit]

If you want to use torrent technology for downloads, you first save a so-called torrent file (.tor or .torrent) on your computer, which was previously created with a torrent client. Both the IP address and the host name of the tracker are stored in this data record, which is a few kilobytes in size. The file also provides information on the size and name of the content. In addition, the torrent file contains a list with the corresponding checksums of the individual files, since the contents of the data are downloaded "in pieces" in order to be reassembled at the target.

A created torrent file is linked by the person who created it first with the corresponding data record on his computer. Example: A seeder makes a music track available as a torrent file. This data record contains the title, file size, etc. At the same time, this data record links to the music title on his hard drive. If others want to find the torrent that has been created, you can use special programs, the so-called "trackers". There, the ID of the torrent and the IP addresses of the peers that can offer the same file are stored. Many such websites have established themselves as trackers on the web. A well-known service is "The Pirate Bay".

If the desired torrent is available, a user can download this data with the help of an appropriate client. The client uses a list that it receives from the tracker to check how many other peers also want to download the file in question and how many peers are offering this file. Then the download of the individual "chunks", ie the individual segments, begins. At that moment, the peculiarity of the torrent system comes into effect, because each peer who downloads it immediately releases its downloaded file to others who want it. Those who only offer files and do not download anything are called “seeders”. The counterpart to this is the “leecher”. It only downloads and does not share any data.

Another special feature of the torrent system is that in the swarm of peers only the file that relates to the requested torrent is exchanged. This creates a separate network for each torrent. There are therefore no links to other files.

Benefit [edit]

The basic idea of ​​torrenting is to share large files with other users over the internet. Torrent technology is very suitable for this. Data can be transmitted even faster, especially due to the increasing Internet speed. Due to the fact that a separate network is formed for each torrent, torrent technology is often considered a secure way of exchanging data.

Criticism [edit]

Torrents are widely used to illegally copy videos, music, or computer games. Because these are copyright infringements, torrent services such as file sharing services are increasingly being targeted by government agencies in the US and Europe. Large file sharers such as "The Pirate Bay" have even been closed in some cases.[1] It has therefore been a long-standing debate whether owning a torrent file is considered a copyright infringement in itself. To take action against copyright infringements, Google updated the Pirate Update in October 2014.
