Mainline DHT
Mainline DHT is the name given to the Kademlia-based distributed hash table (DHT) used by BitTorrent clients to find peers via the BitTorrent protocol. The idea of using a DHT for distributed tracking in BitTorrent was first implemented in Azureus 2.3.0.0 (now known as Vuze) in May 2005, from which it gained significant popularity. Unrelated but around the same time, BitTorrent, Inc. released a similar DHT into their client called Mainline DHT, and thus popularized the use of distributed tracking in the BitTorrent protocol. Measurement showed that by 2013, the concurrent number of users of Mainline DHT is from 16 million to 28 million, with intra-day changes of at least 10 million. Description Mainline DHT is based on the popular Kademlia DHT design. Previous to usage of a DHT for distributing peers, trackers were the only method of finding peers. The key feature of using the DHT over trackers is that the decentralized approach favours the nature of the BitTorrent protocol. T ...

Kademlia
Kademlia is a distributed hash table for decentralized peer-to-peer computer networks designed by Petar Maymounkov and David Mazières in 2002. It specifies the structure of the network and the exchange of information through node lookups. Kademlia nodes communicate among themselves using UDP. A virtual or overlay network is formed by the participant nodes. Each node is identified by a number or ''node ID''. The ''node ID'' serves not only as identification, but the Kademlia algorithm uses the ''node ID'' to locate values (usually file hashes or keywords). In order to look up the value associated with a given key, the algorithm explores the network in several steps. Each step will find nodes that are closer to the key until the contacted node returns the value or no more closer nodes are found. This is very efficient: like many other s, Kademlia contacts only O(\log n) nodes during the search out of a total of n nodes in the system. Further advantages are found particularly in ...

User Datagram Protocol
In computer networking, the User Datagram Protocol (UDP) is one of the core communication protocols of the Internet protocol suite used to send messages (transported as datagrams in packets) to other hosts on an Internet Protocol (IP) network. Within an IP network, UDP does not require prior communication to set up communication channels or data paths. UDP uses a simple connectionless communication model with a minimum of protocol mechanisms. UDP provides checksums for data integrity, and port numbers for addressing different functions at the source and destination of the datagram. It has no handshaking dialogues, and thus exposes the user's program to any unreliability of the underlying network; there is no guarantee of delivery, ordering, or duplicate protection. If error-correction facilities are needed at the network interface level, an application may instead use Transmission Control Protocol (TCP) or Stream Control Transmission Protocol (SCTP) which are designed for this ...

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. The ad-free freeware client includes c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shareaza
Shareaza is a peer-to-peer file sharing client running under Microsoft Windows which supports the gnutella, Gnutella2 (G2), eDonkey, BitTorrent, FTP, HTTP and HTTPS network protocols and handles magnet links, ed2k links, and the now deprecated gnutella and Piolet links. It is available in 30 languages. Shareaza was developed by Michael Stokes until June 1, 2004, and has since been maintained by a group of volunteers. On June 1, 2004, Shareaza 2.0 was released, along with the source code, under the GNU General Public License (GPL-2.0-or-later), making it free software. Features Multi-network Shareaza can connect to gnutella, G2, eDonkey and BitTorrent. Shareaza hashes its files for all networks, and then distributes those hash values on G2. This allows Shareaza to download one file from several networks at once. When another client connected to G2 finds such a file, it is given the hash values for all networks and can search on the other networks with their respectiv ...

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] |
BitComet
BitComet (originally named SimpleBT client from versions 0.11 to 0.37) is a cross-protocol BitTorrent, HTTP and FTP client written in C++ for Microsoft Windows and available in 52 different languages. Its first public release was version 0.28. The current BitComet logo has been used since version 0.50.

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 ...

Transmission (BitTorrent Client)
Transmission is a BitTorrent client which features a variety of user interfaces on top of a cross-platform back-end. Transmission is free software licensed under the terms of the GNU General Public License, with parts under the MIT License. Features Transmission allows users to quickly download files from multiple peers on the Internet and to upload their own files. By adding torrent files via the user interface, users can create a queue of files to be downloaded and uploaded. Within the file selection menus, users can customise their downloads at the level of individual files. Transmission also seeds, that is, it will automatically share downloaded content. Transmission allows the assigning of priorities to torrents and to files within torrents, thus potentially influencing which files download first. It supports the Magnet URI scheme and encrypted connections. It allows torrent-file creation and peer exchange compatible with Vuze and μTorrent. It includes a built-in web se ...

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 ...

Bencode
Bencode (pronounced like ''Bee-encode'') is the encoding used by the peer-to-peer file sharing system BitTorrent for storing and transmitting loosely structured data. It supports four different types of values: * byte strings, * integers, * lists, and * dictionaries (associative arrays). Bencoding is most commonly used in torrent files, and as such is part of the BitTorrent specification. These metadata files are simply bencoded dictionaries. Bencoding is simple and (because numbers are encoded as text in decimal notation) is unaffected by endianness, which is important for a cross-platform application like BitTorrent. It is also fairly flexible, as long as applications ignore unexpected dictionary keys, so that new ones can be added without creating incompatibilities. Encoding algorithm Bencode uses ASCII characters as delimiters and digits. * An integer is encoded as i''''e. Leading zeros are not allowed (although the number zero is still represented as "0"). Negative value ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed Hash Table
A distributed hash table (DHT) is a distributed system that provides a lookup service similar to a hash table: key–value pairs are stored in a DHT, and any participating node can efficiently retrieve the value associated with a given key. The main advantage of a DHT is that nodes can be added or removed with minimum work around re-distributing keys. ''Keys'' are unique identifiers which map to particular ''values'', which in turn can be anything from addresses, to documents, to arbitrary data. Responsibility for maintaining the mapping from keys to values is distributed among the nodes, in such a way that a change in the set of participants causes a minimal amount of disruption. This allows a DHT to scale to extremely large numbers of nodes and to handle continual node arrivals, departures, and failures. DHTs form an infrastructure that can be used to build more complex services, such as anycast, cooperative web caching, distributed file systems, domain name services, instant ...
