The Centralization of BitTorrent Networks

Writes writes writes writes "A group of graduate students from the University of Washington have posted a a new independent report about the extent of centralization in regards to BitTorrent communities. The report indicates that irrespective of the recent damage dealt to global torrent sites, the communities are still very active, even despite their large degree of centralization (and perhaps exposure/liability). Furthermore, the report attempts to determine if the torrent communities follow the 80/20 rule, by measuring the Long Tail of torrent distribution."

    So seriously, is BitTorrent dead?

    No. Well, we don't think so, at least.


    That should have read, "is BitTorrent for Warez dead?" And no, it's not, but it probably won't appear like suprnova.org did again...

    Is BitTorrent dead? No, it will never die. Just as FTP for Warez dwindled and other transfer services took over (IRC, Napster, Kazaa, BitTorrent, foo) it didn't kill it. FTP, IRC, BT, foo, all have valid reasons for existing other than warez.

    BT though, above all the others, is actually really useful for trasferring large files quickly. Yeah, it's not good for the long term but I'm sure someone will come up with something that will make the protocol attractive for use outside of the Warez arena.

    It's just that the warezkids are all about picking up new tech and using it. It's their nature as they are generally tech oriented.

    I wish I could be a grad student and publish a bunch of bullshit with graphs and get my degree!

      I personally hope that the public sites die, since they don't use registration, people shamelessly leech files and don't even come close to the 1:1 ratio that's needed for the network to thrive. I'll just stick with places that require registration, track stats, ban leechers, and thank me for contributing. There's probably 4 or 5 sites that I use for that sort of thing(thing being TV or movies). Besides, on smaller sites, there's more of a community, and the speeds stay good, much like yours did :)

      A 1:1 ratio for everybody is mathematically impossible. For every byte uploaded, you have a byte downloaded. You also have at least one person who doesn't download anything at all, the original seeder. The average ratio of the entire network is always 1:1, and the average of the entire network minus original seeders will always be less than that. You will always have people who don't have a 1:1 ratio even if everybody is super-nice and lets their torrents run forever after they finish.

  2. A matter of access and exposure by teiresias · · Score: 4, Insightful

    This isn't really suprising.

    Whether it's FTP ip's, P2P network names, or in this case centralized BitTorrent servers, it all matters on who has access to these sites and how much exposure that site has.

    If say SuperNova was a registration only site it might have stayed open for another couple months. If say SuperNova was a registration site which only registered friends and known people, there's even less of a chance of being taken down.

    Any large publicly available distrobution method for illegal digital products will attract the attention of the authorities and be brought down. Small, regulated, private networks will continue to run despite a crack down. This has always been true.

    But than, for the authorities, it really is more important to take down the larger sites not eliminating the problem.

      It's like anything "illegal". There's always a thriving underground arena to trade your stuff. The authorities can easily bring down the large and open ones cutting off the general unknowing public to it. That will eliminate 95% of the "problem".

      The other 5% would find out how to get it regardless of whether it was public or not.

      I guess they just hoped they could scare most people into stopping.

    Sure people are easily tracked who use bit torrent. I doubt they really care. Bit Torrent allows easy ways to find files. It may not be mainstream easy, but it is very easy to use. You can get tons of movies/music/tv shows/warez with little effort, much easier than tracking down ftps and getting access from someone/ using kazaa and hoping what you download is really what you think it is, etc. People want easy access to filez! THey don't care about getting caught

    What's the harm in a C&D, though?

    Seriously--say you consider setting up a torrent repository. What's the deterrant in "maybe they'll ask me to stop later"? I'm no worse off later than I would have been if I had never started the repository, and I provided a service for a little while.

  6. This changes nothing by Jahz · · Score: 4, Insightful

    It is true that the closing of Suprnova.org was a mighty blow to the availibility of torrents, but it changes nothing in the long run. In a few weeks there will be a new uber-big torrent directory. Actually, there already are a few.

    In my opinion, BitTorrent is still a new and wandering technology. It is being employed in many different way and still has plenty of undiscovered potential. It is already an excellent way to cheaply distribute free software (i.e. linux distros). It is also a great way to distribute 0-day files with minimal liability and cost.

    BitTorrent is still the best way to get less-than-legal new (...brand new) tv show episodes, movies and multi-platform games. There are many reasons for this. Namely, it spreads liability across hundreds or thousands of individuals, not a single server. Secondly, .torrent files are very small and easy to spread. Finally, even if every peer has a slow dialup connection, a broadband downloader can still reach some very respectable speeds. Not to mention that most of the clients preform superb error checking on each peice of data.

    As a protocal, BT is perhaps the most promising for large file distribution. There are some faster, and some even less centralized protocals, but in the end BT beats them all.

    If you are concerned about BT's future as a method of underground file distribution: worry not. The torrent underground has its roots firmly planted in IRC. In fact, some of the best sites for well seeded torrents are just web-front ends to IRC channels (i.e. tvtorrents). BT will exist until something better comes along. That is the way of things.

    note: this is not directly in response to the articles, rather it is in response to some of the other /. posts.

  8. Re:BitTorrent's usefulness? by Morosoph · · Score: 2, Insightful
    The thing about bittorrent is that it is a trading protocol. Your upload is your 'bid', and you can receive a corresponding download. The trouble is that if your upload 'bid' is high, there won't be download 'bids' of equal magnitude, so you have to accept what you can get.

    It might also be, as others have suggested, that your upload is choking your download.

  9. That's nice, but ... by magicianuk · · Score: 3, Insightful

    ... it's really hard to meet the 1:1 etc. requirements unless you get there early.

    The number of torrents I start downloading and then find that there's no more seeds etc. so I get 90% of a large file and then I'm stuck ... I can stay up and be prepared to feed that 90% downstream but that just means more people with an incomplete RAR/ZIP/AVI whatever.

    And if I get to a download late, I can sit there and download, say 100Mb fairly quickly from all those nice seeders (say 10 seeders and just two new downloaders), but then anyone new that comes along has 12 sites feeding and since 10 have 100% and then there's me with whatever I've downloaded so far, I hardly ever get a chance to feed downstream, so I sit there for days and never get anywhere near 1:1)

    There needs to be a better way of rating people who want to be good torrent users ... for example, keeping a torrent open should count for 4% an hour, so that if you keep the torrent open for a day after you've finished downloading, even if no-one feeds from you, you still get credit for making the torrent available.

  10. Re:There are better ways to spend your money. by Cereal+Box · · Score: 4, Insightful

    Watching a poor-quality .avi of a movie is a completely different experience than seeing a much better version - even a rented VHS.

    You must not have gotten the memo. Movies on DVD are ripped to MPEG4, and generally look indistinguishable from the DVD itself (and many times include the actual Dolby Digital 5.1 audio track). In essence, you're downloading a copy of the movie that many are hard pressed to differentiate from a DVD.

    In the case of movies running in the theater, ones shot from camcorders are watchable but not in excellent quality, whereas those ripped from a screener DVD (this practice may have been discontinued recently, I'm not sure) are quite excellent.

    The same is true with music uploaded at 128 kbs as compared to straight off the CD.

    Of course, no one releases albums in 128Kbps anymore, it's all 192Kbps or VBR. Throw those tracks on a CD and most people would be hard pressed to tell the difference.

    The "downloaded copies have poor quality, so that's why people will still buy the product" argument doesn't hold that much water in a lot of cases. Most people would gladly take 99% quality at 0% price rather than 100% quality and 100% price. THAT'S what the movie studios and record companies have to compete with. There are far fewer altruistic downloaders than you may think.
