GUI

Azureus's swarm feature

Azureus allows users to download multiple files in a single graphical user interface (GUI). The program also features detailed statistics and a large number of user-configurable settings. While downloading a file, the user can view several different statistics including: Image File history File links Size of this preview: 800 × 582 pixel Image in higher resolution (1276 × 928 pixel, file size: 52 KB, MIME type: image/png) Also note the file being downloaded is the project reality BF2 modification which is freely available here realitymod. ...

• Current download and upload speeds and estimated time remaining
• The percentage of each file completed and information on the "pieces" (small parts of the complete file) still needed including the piece number and availability
• File names, sizes and levels of completion for specific files within the download directory (BitTorrent allows a user to create a torrent file for an entire directory). It is also possible to prevent certain files from downloading.
• Peer data including IP addresses (and country with the use of a plugin), the speeds at which you are downloading and uploading to/from them, the port they are running BitTorrent on, and the BitTorrent client they are using
• The total and average "swarm speeds"^[2]

Since version 3.0, Azureus starts with an interface designed to promote Vuze content. It is possible to switch to the classical user interface and bypass the Vuze layer by selecting Tools/Options/Interface/Start/Display Azureus UI Chooser.

Features

Azureus's advanced statistics page

Azureus allows users to specify maximum upload and download speeds and is configurable. Azureus also allows users to open some files that have been completed before the entire torrent from within the program. Additionally, Azureus can serve as its own tracker, allowing users to share their own files with others without uploading it to any site. Azureus also supports tracker-less torrents via DHT. Azureus supports Message stream encryption, an anti-throttling method. Peer exchange and the magnet: URI scheme are supported. An integration with the Nodezilla Grid Network is implemented as a plugin, enabling the anonymous storage, sharing and publication of torrent files. Azureus also features multiple ways of viewing a file, such as Swarm, Peers, and Pieces.

Unlike all other popular BitTorrent clients, Azureus supports the I2P and Tor networks, allowing users to transfer files over the BitTorrent network anonymously. I2P (originally short for Invisible Internet Project,[1] though it is not commonly referred to by this name anymore) is a free and open source project building an anonymous network (or, more accurately, a pseudonymous overlay network). ... Tor (The Onion Router) is a free software implementation of second-generation onion routing – a system enabling its users to communicate anonymously on the Internet. ...

Plugins

Azureus also offers a range of plugins designed to make using the program easier or to give the more experienced user more options and more advanced tools with which to configure Azureus. Some plugins available are as follows: For other uses, see Plug in. ...

Notable plugins

• 3D View - Opens a 3D view of the peer swarm of peers in a new tab. (Windows only)
• Advanced Statistics - Gives advanced information on the progress, activity and transfer of torrents.
• Auto Categorizer - Automatically categorized torrents depending on their file types.
• Auto Speed - Automatically adjust global upload speed limit based on network latency.
• Auto Seeder - Automatically seeds files based on the contents of torrent and data directories.
• Chat - Lets users chat by cr3.2 Enhanced Protocol
• AzSMRC - provides remote control and multiuser features
• DHT Scraper - Distributed Database (DHT) torrent scraper.
• Firefrog - A simple Firefox-style download manager.
• MainlineDHT - Allows Azureus to use the Mainline DHT
• Ono - Attempts to find and connect to peers "closer" (in the network sense) to the user in an attempt to increase speed. Results from over 100,000 users indicate that it finds peers that give orders of magnitude lower latencies and higher average download rates than those picked at random. Note that this plugin collects and stores data from users (but not any information that can be tied to what you are downloading, see ^[3]), and you can turn off the data collection if it bothers you.
• Peer Injector - Allows one or more peers to be manually injected into torrents for explicit connection purposes.
• Progress Bar - Adds a graphical progress bar column to MyTorrents.
• ScaneRSS - imports Torrents from RSSFeeds based on Rules
• SafePeer - blocks all peers that appear on a list of entities believed to be hostile to file sharers
• Status Mailer - Sends an email via SMTP when a download starts and/or completes.
• Stuffer - Client banning plugin with support for use of regular expressions.
• Upload Shaper - Automatically adjust global upload speed limit based on download speed * factor.
• Team Seeder - Helps seed torrents that are tracked by Azureus when there are a dedicated team of seeders.

Azureus now supports an enhanced inter-client messaging protocol, which is aimed at allowing plugins to use the connections created by Azureus to add functionality to the program. Other clients developers can see the specifications for this protocol at the Azureus Wiki. Plugin developers can check the plugin javadocs to see how to use it. For example, the JPC (now discontinued) and Chat plugins make use of this messaging extension. Windows redirects here. ... This article is about the computer terms. ...

DHT

Azureus version 2.3.0.0 introduced the Distributed Database function (a form of DHT, namely Kademlia), which is a decentralization of the BitTorrent protocol, making it more independent from trackers. For users of Azureus 2.3.0.0 or newer, this allows a user to download a file from peers even when the original tracker is unavailable or has been shut down. The downside to this is that private tracker operators, with membership requirements, are required to explicitly alter their torrent files so that the Azureus client knows not to share peer information about that swarm. Some critics also say that this is simply "reinventing the wheel," referring to earlier peer-to-peer protocols and programs the weaknesses of which BitTorrent was praised for overcoming. Others see it as an evolution of the BitTorrent protocols to circumvent enforcement actions of the entertainment industry. Azureus uses its own form of DHT incompatible with the official BitTorrent client offered by BitTorrent, Inc.. All of the other clients, including BitComet and µTorrent, support the official DHT^[4]. For compatibility purposes the mainline DHT is available to Azureus users as a plugin. Distributed hash tables (DHTs) are a class of decentralized distributed systems that provide a lookup service similar to a hash table: (name, value) pairs are stored in the DHT, and any participating node can efficiently retrieve the value associated with a given name. ...

Decentralization is the process of dispersing decision-making closer to the point of service or action. ... Look up Protocol in Wiktionary, the free dictionary. ... Reinventing the wheel is a phrase that means a generally accepted technique or solution is ignored in favor of a locally invented solution. ...
