Super-seeding
In file sharing, super-seeding (aka 'Initial Seeding') is an algorithm developed by John Hoffman for the BitTorrent communications protocol that helps downloaders become uploaders more quickly, but it introduces the danger of total seeding failure if there is only one downloader. The algorithm applies when there is only one seed in the swarm. By permitting each downloader to download only specific parts of the files listed in a torrent, it allows peers to start seeding more quickly. Peers attached to a seed with super-seeding enabled therefore distribute pieces of the torrent file much more readily before they have completed the download themselves. In 2003, BitTornado became the first BitTorrent client to implement the algorithm. Effects Testing by one group found that super seeding can help save an upload ratio of around 20%. It works best when the upload speed of the seed is greater than that of individual peers. Super seeding transfers stall when there is only one downloa ...

Comparison Of BitTorrent Clients
The following is a general comparison of BitTorrent clients, which are computer programs designed for peer-to-peer file sharing using the BitTorrent protocol. The BitTorrent protocol coordinates segmented file transfer among peers connected in a swarm. A BitTorrent client enables a user to exchange data as a peer in one or more swarms. Because BitTorrent is a peer-to-peer communications protocol that does not need a server, the BitTorrent definition of ''client'' differs from the conventional meaning expressed in the client–server model. Bram Cohen, author of the BitTorrent protocol, made the first BitTorrent client, which he also called BitTorrent, and published it in July 2001. Many BitTorrent programs are open-source software; others are freeware, adware or shareware. Some download managers, such as FlashGet and GetRight, are BitTorrent-ready. Opera 12, a web browser, can also transfer files via BitTorrent. In 2013 Thunder Networking Technologies publicly revealed that ...

Glossary Of BitTorrent Terms
This is a glossary of jargon related to peer-to-peer file sharing via the BitTorrent (protocol), BitTorrent protocol. Terms Availability :(Also known as distributed copies.) The number of full copies of a file (or set of files and directories) directly available to the client. Each seed adds 1.0 to this number, as they have one complete copy of the file. A connected peer with a fraction of the file available adds that fraction to the availability, if no other peer has this part of the file. :''Example:'' a peer with 65.3% of the file downloaded increases the availability by 0.653. However, if two peers both have the same portion of the file downloaded - say 50% - and there is only one seeder, the availability is 1.5. :Sometimes "distributed copies" is considered to be "availability minus 1". So if the availability is 1.6, the distributed copies will be 0.6 because it is only counting the "copies" of the file. Choked :Describes a Glossary of BitTorrent terms#Peer, peer to whi ...

μTorrent
μTorrent, or uTorrent (see pronunciation) is a proprietary adware BitTorrent client owned and developed by Rainberry, Inc. with over 150 million users. It is the most widely used BitTorrent client outside China; globally only behind Xunlei. The " μ" (Greek letter " mu") in its name comes from the SI prefix "micro-", referring to the program's small memory footprint: the program was designed to use minimal computer resources while offering functionality comparable to larger BitTorrent clients such as Vuze or BitComet. μTorrent became controversial in 2015 when many users unknowingly accepted a default option during installation which also installed a cryptocurrency miner. The miner was removed in later versions, but had already done irreversible damage to μTorrent's reputation. The program has been in active development since its first release in 2005. Although originally developed by Ludvig Strigeus, since December 7, 2006, the code is owned and maintained by BitTorrent, In ...

Libtorrent
libtorrent is an open-source implementation of the BitTorrent protocol. It is written in and has its main library interface in C++. Its most notable features are support for Mainline DHT, IPv6, HTTP seeds and μTorrent's peer exchange. libtorrent uses Boost, specifically Boost.Asio to gain its platform independence. It is known to build on Windows and most Unix-like operating systems (OS X, Linux, and many BSDs). libtorrent is kept up to date with bittorrent extensions that developers deem most useful, and is actively being optimized to work in a broader set of environments. Many of its features can be disabled at compile-time to not include code that would not be used in a particular use case. It aims to be the most suitable libtorrent implementation for embedded devices as well as desktops and seed-servers. Some of its implementation details are described in the features section. The original author of libtorrent is Arvid Norberg. It is the first client to support the ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RTorrent
rTorrent is a text-based BitTorrent client written in C++, based on the ncurses and libTorrent (not to be confused with libtorrent) libraries for Unix, whose author's goal is "a focus on high performance and good code". Technical details The library differentiates itself from other implementations by transferring data directly between file pages mapped to memory by the mmap() function and the network stack. On high-bandwidth connections, it claims to be able to seed at three times the speed of the official client. rTorrent packages are available for various Linux distributions and Unix-like systems, and it will compile and run on nearly every POSIX-compliant operating system, such as FreeBSD and macOS. rTorrent uses the ncurses library and is suitable for use with GNU Screen or Tmux; it uses commands such as Carriage return to load a torrent, after which ^S can be used to start a torrent (where ^ is shorthand for Ctrl key), backspace can be used to automatically start a ...

File Sharing
File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books. Common methods of storage, transmission and dispersion include removable media, centralized servers on computer networks, Internet-based hyperlinked documents, and the use of distributed peer-to-peer networking. File sharing technologies, such as BitTorrent, are integral to modern media piracy, as well as the sharing of scientific data and other free content. History Files were first exchanged on removable media. Computers were able to access remote files using filesystem mounting, bulletin board systems (1978), Usenet (1979), and FTP servers (1970's). Internet Relay Chat (1988) and Hotline (1997) enabled users to communicate remotely through chat and to exchange files. The mp3 encoding, which was standardized in 1991 and substantially reduced the size of audio files, grew to widespread use in ...

Deluge (software)
Deluge BitTorrent Client is a free and open-source, cross-platform BitTorrent client written in Python. Deluge uses a front and back end architecture where libtorrent, a software library written in C++ which provides the application's networking logic, is connected to one of various front ends including a text console, the web interface and a graphical desktop interface using GTK through the project's own Python bindings. Deluge is released under the terms of the GPL-3.0-or-later license. Features Deluge aims to be a lightweight, secure, and feature-rich client. To help achieve this, most of its features are part of plugin modules which were written by various developers. Starting with version 1.0, Deluge separated its core from its interface, running it instead in a daemon (server/service), allowing users to remotely manage the application over the web. Deluge has supported magnet links since version 1.1.0 released in January 2009. History Deluge was started by two m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vuze
Vuze (previously Azureus) is a BitTorrent client used to transfer files via the BitTorrent protocol. Vuze is written in Java, and uses the Azureus Engine. In addition to downloading data linked to .torrent files, Azureus allows users to view, publish and share original DVD and HD quality video content. Content is presented through channels and categories containing TV shows, music videos, movies, video games, series and others. Additionally, if users prefer to publish their original content, they may earn money from it. Azureus was first released in June 2003 at SourceForge.net, mostly to experiment with the Standard Widget Toolkit from Eclipse. It later became one of the most popular BitTorrent clients. The Azureus software was released under the GNU General Public License, and remains as a free software application. It was among the most popular BitTorrent clients. However, the Vuze software added in more recent versions is proprietary and users are required to accept these m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tixati
Tixati is a proprietary Linux and Windows BitTorrent client written in C++. It has standalone and portable versions with each new client version. Features In addition to standard BitTorrent client-sharing functions, Tixati provides integral chatrooms with channel chat as well as private messaging being encrypted. Chatrooms can be either public or secret. Users are allowed to optionally share lists of magnet or URL links which are then searchable across all channels a user is joined to. Browsing a specific user's share list is also supported. The channels also allow for streaming audio and video media. Fopnu Since July 20, 2017, the developers of Tixati have released regular updates of a new P2P system (network and client) called ''Fopnu''. It's visually similar to Tixati but Fopnu is not a torrent client. Fopnu is a decentralized network with the latest advances in P2P technology, pure UDP and with all communications being encrypted.
