In the article indexing is better described as in BitTorrent index. merging or splitting it? mabdul 0=* 14:11, 24 October 2008 (UTC)

List of file transfer protocols

should we add bittorrent and other P2P protocls to this list? mabdul 0=* 16:55, 4 February 2009 (UTC)

I think the BitTorrent protocol would fit in there. The other P2P clients are a bit more complex, as FastTrack and Gnutella both use simple HTTP for the actual file transfer. Rurik (talk) 14:47, 5 February 2009 (UTC)

The section Implementations should be updated based on information about the unofficial fork of torrentflux, torrentflux-b4rt. The functions "ZIP compression, RAR decompression and Playstation 3 streaming & download support" are in torrentflux-b4rt, along with other functions. —Preceding unsigned comment added by (talk) 03:50, 18 February 2009 (UTC)

ratio - how it exactly works?

There is "ratio" mensioned in article (in "The leech problem" subsection) but nowhere is described how trackers count it. Is client application sending information about how many data it down- and uploaded? So why it sholdn't report fake amount of uploaded data? So maybe trackers take information about one client from other peers? —Preceding unsigned comment added by (talk) 21:37, 23 May 2009 (UTC)

When clients "check in" with the tracker, usually every 30 minutes, they send information about how many total bytes they've uploaded and downloaded. Rurik (talk) 22:59, 23 May 2009 (UTC)
Ok, so maybe you write this to article? (talk) —Preceding undated comment added 23:42, 23 May 2009 (UTC).

elaboration needed on article

explain the "swarm", it is still a rather unknown concept without description. Murakumo-Elite (talk) 08:44, 25 June 2009 (UTC)

The swarm is the collection of peers that are participating in a single torrent. I can't see a good place to put this in the article, though. Theymos (talk) 18:03, 25 June 2009 (UTC)
I ask about this because there are times where I run a torrent with 0(96) and 20(187)[or relative numbers] and I have NEVER once gotten a clear lock on the complete files, weeks would go by and still no chance at completing it. This was always something I needed to understand to curtail any frustration. Murakumo-Elite (talk) 07:11, 26 June 2009 (UTC)
The tracker is sending you the locations of peers in the swarm, but they are not able to connect to you because your firewall/router/proxy is blocking them. I can't be more specific than that without more information about your configuration, and this talk page is for discussing the article. Ask at the reference desk if you can't figure it out. Theymos (talk) 07:55, 26 June 2009 (UTC)

checksum or SHA-1 hash code?

Not consistent (talk) 22:38, 26 June 2009 (UTC)

It is a SHA-1 hash code but it is only used as a unique identifier for the swarm. It isn't used to verify the contents of the data, so technically not a checksum. Rurik (talk) 00:07, 27 June 2009 (UTC)
Each 64-4096MB piece also gets a SHA-1 hash, which is used to verify the data's integrity. Theymos (talk) 00:59, 27 June 2009 (UTC)
You're right, I misread the content. In terms of consistency, the two aren't really interchangeable. The checksum is the 'what', the SHA-1 is the 'how'. Rurik (talk) 01:29, 27 June 2009 (UTC)
I agree. The article is fine as is and there is no consistency problem. Theymos (talk) 02:05, 27 June 2009 (UTC)


Many files can not be downloaded due to lack of seeding. —The preceding unsigned comment was added by Ergn (talkcontribs) 01:06, August 23, 2007 (UTC).

To address the problem, section "Content unavailability" was added. —Preceding unsigned comment added by (talk) 15:45, 27 January 2010 (UTC)

Are Animated gifs really a good idea?

This is the second time in a few days I've had to put my hand over part of the screen so I don't have an irritating flashing image making the article really difficult to read. Can't there just be a static image linked to the animation? I'm not sure the animation really illustrates much anyway. See, all that flashing has made me bad tempered! —Preceding unsigned comment added by (talk) 00:04, 26 April 2008 (UTC)

The concept of the animated gif doesn't really bother me, but it would be a lot more useful as an article supplement if it went slower. Right now, I feel like it cycles through too quickly to be a good illustration. I have no idea if this is something that can be changed or not, though. Anneagain (talk) 22:24, 30 September 2009 (UTC)
Hitting the escape key in the Firefox browser halts any animated gifs. Quite handy. :) (talk) 17:18, 2 April 2010 (UTC)
Good idea - this works in IE & FF. It's an accessibility issue. I've added "To stop animation, click browser Stop or hit ESC key." to the Image box caption. --Lexein (talk) 00:39, 3 April 2010 (UTC)
Anneagain, you're not meant to 'understand' all the transfers - most of them are random. It's just to show the idea that once the file is 'out there', the original server has little to do while others exchange parts of the file, and many users each end up with a full copy. --Nigelj (talk) 21:02, 2 April 2010 (UTC)
I'm not sure this is the best solution, as not all users are going to be using IE/FF, and some don't use a browser with a 'click-able stop button', some don't have a mouse at all, etc. I really think that this thing is an eyesore, like the first poster, and I think that it should be added as a small thumbnail of the 8 frames shown in 'film roll style', as in one below another, in small thumbnail size of course, which upon clicking leads to the animation. If there isn't some way to have this picture be non-animated, at least to start with, I don't feel it should be on this page, it doesn't add enough to the article.
If anyone agrees/has any more thoughts, I'm perfectly fine with doing all of the legwork with the image and article editing, seeing as there are several opinions, all equally valid, maybe I'll wait for a response or the very least, can I at least shrink it? Nigtv (talk) 22:04, 7 April 2010 (UTC)
Edit the image and make the cycles bigger so that the image at the end is slower. Wonder why it should be so fast: in my opera it is really slow (a bit to slow for me)... But i wouldn't remove the animated image! mabdul 14:38, 8 April 2010 (UTC)
As soon as I have a free second or two, I'm going to try that, as well as lowering the number of clients and pieces in the image. This image would work much better with only 3-4 clients and 3-5 pieces. kifo 09:25, 15 April 2010 (UTC) —Preceding unsigned comment added by Nigtv (talkcontribs)

What goes inside the torrent

I think this article could be improved if an expert can add information regarding what goes inside a .torrent file. I was looking it up myself but is really complex, but I am sure someone familiar can add this information so more people could get knowledge on what is inside the torrent file itself.--Camilo Sanchez (talk) 17:23, 5 August 2009 (UTC)

I've started working on this: User:TomFitzhenry/.torrent
On the talk page I've posted a todo list and some things that I'm unsure how to present: User_talk:TomFitzhenry/.torrent -- TomFitzhenry (talk) 10:29, 21 October 2009 (UTC)

Does a protocol really have a logo? You quite sure it isn't the logo of the BitTorrent INC or perhaps of the official client (also by the same name)? (talk) 20:24, 20 September 2009 (UTC)


The text says SHA1 is used for the hashes, however this is demonstrably incorrect. Create a file with a single null in it (SHA1 hash=5ba93c9db0cff93f52b521d7420e43f6eda2784f), create .torrent file, open in client (i.e. Transmission), click on properties and note the hash given is different. This should be explained here. —Preceding unsigned comment added by (talk) 17:16, 12 October 2010 (UTC)

Really? You guessed at the behavior (getting it wrong) and then changed the article instead of, say, looking up one of the many copies of the spec? Here's one copy. Here's a Google query you could have used. Brian Geppert (talk) 10:15, 20 November 2010 (UTC)


I'm probably going to cut out the Sandvine part for inaccuracy.

Sandvine has CLAIMED for a long time that their products effectively identify and block Bittorrent traffic. While this statement is technically true, it also blocks huge swaths of other applications because of false positives. The cited article used this equation for traffic shaping uploads only:

For a period of time(x), from on single IP, fixed UDP port -> many destination IP(y), fixed or random UDP ports

Of course, this is not what Sandvine was doing. Sandvine ONLY blocks TCP, as there is no equivalent to the TCP RST command in UDP. So they used something like the above equation for TCP traffic. And lots and lots of legitimate TCP traffic (XBOX Live, for example) uses this pattern. So when deployed on Comcast, Sandvine initially blocked or throttled LOTS of applications.

This kind of pattern analysis is desirable because (as per the article) it's much cheaper than deep packet inspection(DPI). The problem is that it doesn't work in practice. —Preceding unsigned comment added by (talk) 20:13, 15 March 2010 (UTC)


I note the ACS:Law article is marked as semi-orphaned. Seems a link from bittorrent would be highly appropriate. ;-) —Preceding unsigned comment added by (talk) 11:36, 10 April 2010 (UTC)

Legal Issues

The article states that Mininova has been shut down. This is not entirely true. While Mininova has removed all content that infringes copyright in a manner not pursuant with the law, they still distribute torrents using a content-distributor model using a verification system to make sure the uploader of the torrent does in fact have legal rights to distribute said content [1]. A good majority of the content is available, if I'm not mistaken, under some sort of open-content licensing (such as some Creative Commons license). Alex (talk) 10:48, 1 February 2011 (UTC)

  • The Legal_issues_with_BitTorrent page reflects that Mininova hasn't been shut down but has redirected its efforts. The legal issues section of this article needs someone more articulate than I to summarize that for this article so that both are in agreement.Alex (talk) 12:41, 3 February 2011 (UTC)
