For this reason, methods have been developed to disguise BitTorrent traffic in an attempt to thwart these efforts. Reports in August indicated that Comcast was preventing BitTorrent seeding by monitoring and interfering with the communication between peers. Protection against these efforts is provided by proxying the client-tracker traffic via an encrypted tunnel to a point outside of the Comcast network. Another unofficial feature is an extension to the BitTorrent metadata format proposed by John Hoffman [93] and implemented by several indexing websites.

It allows the use of multiple trackers per file, so if one tracker fails, others can continue to support file transfer. Trackers are placed in groups, or tiers, with a tracker randomly chosen from the top tier and tried, moving to the next tier if all the trackers in the top tier fail. Torrents with multiple trackers can decrease the time it takes to download a file, but also have a few consequences:. Even with distributed trackers, a third party is still required to find a specific torrent.

This is usually done in the form of a hyperlink from the website of the content owner or through indexing websites like isoHunt , Torrentz , BTDigg , Torrentus or The Pirate Bay. The Tribler BitTorrent client is the first to incorporate decentralized search capabilities. With Tribler, users can find. It adds such an ability to the BitTorrent protocol using a gossip protocol , somewhat similar to the eXeem network which was shut down in The software includes the ability to recommend content as well.

After a dozen downloads the Tribler software can roughly estimate the download taste of the user and recommend additional content. In May , researches at Cornell University published a paper proposing a new approach to searching a peer-to-peer network for inexact strings, [96] which could replace the functionality of a central indexing site.

A year later, the same team implemented the system as a plugin for Vuze called Cubit [97] and published a follow-up paper reporting its success. A somewhat similar facility but with a slightly different approach is provided by the BitComet client through its "Torrent Exchange" [99] feature. Whenever two peers using BitComet with Torrent Exchange enabled connect to each other they exchange lists of all the torrents name and info-hash they have in the Torrent Share storage torrent files which were previously downloaded and for which the user chose to enable sharing by Torrent Exchange.

Thus each client builds up a list of all the torrents shared by the peers it connected to in the current session or it can even maintain the list between sessions if instructed. At any time the user can search into that Torrent Collection list for a certain torrent and sort the list by categories. When the user chooses to download a torrent from that list, the.

The BitTorrent specification is free to use and many clients are open source , so BitTorrent clients have been created for all common operating systems using a variety of programming languages. For example, this can be used to centralize file sharing on a single dedicated server which users share access to on the network. The Opera web browser supports BitTorrent, [] as does Wyzo.

BitLet allows users to download Torrents directly from their browser using a Java applet. An increasing number of hardware devices are being made to support BitTorrent. Proprietary versions of the protocol which implement DRM , encryption, and authentication are found within managed clients such as Pando. SET, proposed by researchers Pucha, Andersen, and Kaminsky, works by spotting chunks of identical data in files that are an exact or near match to the one needed and transferring these data to the client if the "exact" data are not present.

Their experiments suggested that SET will help greatly with less popular files, but not as much for popular data, where many peers are already downloading it.

Oversi's ISP hosted NetEnhancer box is designed to "improve peer selection" by helping peers find local nodes, improving download speeds while reducing the loads into and out of the ISP's network. Although the protocol itself is perfectly legal, problems stem from using the protocol to traffic copyright infringing works.

There has been much controversy over the use of BitTorrent trackers. BitTorrent metafiles themselves do not store file contents. Whether the publishers of BitTorrent metafiles violate copyrights by linking to copyrighted works without the authorization of copyright holders is controversial.

Various jurisdictions have pursued legal action against websites that host BitTorrent trackers. High-profile examples include the closing of Suprnova. The Pirate Bay torrent website, formed by a Swedish group, is noted for the "legal" section of its website in which letters and replies on the subject of alleged copyright infringements are publicly displayed.

On 31 May , The Pirate Bay's servers in Sweden were raided by Swedish police on allegations by the MPAA of copyright infringement; [] however, the tracker was up and running again three days later.

In the study used to value NBC Universal in its merger with Comcast, Envisional examined the 10, torrent swarms managed by PublicBT which had the most active downloaders. After excluding pornographic and unidentifiable content, it was found that only one swarm offered legitimate content. In the United States, more than , people have been sued for filesharing on BitTorrent since To achieve high bandwidths, the underlying protocol used is UDP , which allows spoofing of source addresses of internet traffic.

This can be used for Denial-of-service attacks , where users running BitTorrent clients act as amplifiers for an attack at another service. As BitTorrent is a collaborative distributed platform, there is a section of the community that wants solutions to punish and discourage such behaviour. Several studies on BitTorrent have indicated that there exist files, containing malware , available for download via BitTorrent.

Another study [] claims that as much as Due to SHA1 collisions, an attacker can alter the execution path of the executable by serving altered chunks when the victim is downloading the executable using the BitTorrent protocol. Despite the fact that a proof of concept exists, the attack may succeed in very limited cases: By selecting larger chunks i. From Wikipedia, the free encyclopedia.

This has fueled ongoing controversy [ specify ] in the syndication development community as to which entity was the proper publisher of RSS.

One product of that contentious debate was the creation of an alternative syndication format, Atom, that began in June In February , Opera Software followed suit.

In June , the board revised their version of the specification to confirm that namespaces may extend core elements with namespace attributes, as Microsoft has done in Internet Explorer 7. According to their view, a difference of interpretation left publishers unsure of whether this was permitted or forbidden. The RSS format itself is relatively easy to read both by automated processes and by humans alike.

An example feed could have contents such as the following:. When retrieved, reading software could use the XML structure to present a neat display to the end users. Later versions in each branch are backward-compatible with earlier versions aside from non-conformant RDF syntax in 0. Most syndication software supports both branches. The extension mechanisms make it possible for each branch to copy innovations in the other.

For example, the RSS 2. Likewise, the RSS 2. There are also several common outside extension packages available, e. The most serious compatibility problem is with HTML markup.

This behavior has become expected of readers, to the point of becoming a de facto standard, [ citation needed ] though there is still some inconsistency in how software handles this markup, particularly in titles. The primary objective of all RSS modules is to extend the basic XML schema established for more robust syndication of content.

This inherently allows for more diverse, yet standardized, transactions without modifying the core RSS specification. To accomplish this extension, a tightly controlled vocabulary in the RSS world, "module"; in the XML world, "schema" is declared through an XML namespace to give names to concepts and relationships between those concepts.

For example, applications that rely on the Common Feed List of Windows might handle such files as if they were corrupt, and not open them. Interoperability can be maximized by keeping the file size under this limit.

RSS feeds which provide links to. Some services deliver RSS to email inbox, sending updates from user's personal selection and schedules. Both RSS and Atom are widely supported and are compatible with all major consumer feed readers. RSS gained wider use because of early feed reader support.

Technically, Atom has several advantages: The following table shows RSS elements alongside Atom elements where they are equivalent. Several major sites such as Facebook and Twitter previously offered RSS feeds but have reduced or removed support.
