Microsoft Reinvents Bittorrent

Anon E. Muss writes "Microsoft has a new Secure Content Downloader tool that sounds an awful lot like a Bittorrent clone. It's described as a 'peer-assisted technology' where '[e]ach client downloads content by exchanging parts of the file they're interested in with other clients, in addition to downloading parts from the server.' Right now MSCD is just a time-limited preview, intended to support downloads of select Microsoft beta releases (e.g. Visual Studio 2008). If this test goes well, Microsoft will probably start using MSCD for all their large downloads. How do you feel about subsidizing Microsoft's bandwidth costs?"

Blizzard even lists alternative (third party) download sites on their patch page because of this. Besides, they didn't re-invent bittorrent. They stated from the beginning what protocol they were using.

      I see nothing wrong with MS doing this just like I see nothing wrong with bittorrent.

      "How is it a double standard if someone doesn't want to support Microsoft while wanting support a company they like, such as Blizzard?"

      The definition of a double standard is to apply one standard to judge two groups differently for the same infraction because of issues external to the matter at hand. In this instance you want to condemn MS and give Blizzard a free pass because of your stance on open standards. (this seems a bit dubious, every standard Blizzard has is closed, they have sued people in the past for trying to make servers that do the same thing as battle.net and so forth, but I digress) So what you are doing is prettymuch the classic example of a double standard, judging one group differently than another for the same infraction because you dont like them for whatever reason.

      I am not sure if you were being sarcastic or not by asking how applying different standards to different groups based on whether or not you liked them constitutes a double standard. If you were joking then my bad. :)

Only evil packet (protocol) shaping would prevent you from downloading a mere 4 MB file in a few minutes, even if you aren't uploading anything. Fortunally blizzard has alternative ways of downloading patches, but it really shouldn't be nescessary. Bittorrent is not much different than a http/ftp download, except that it is also possible for clients to exchange parts of the file/files between themselves when the server is overloaded.

There are plenty of screwy things that Microsoft does and always a contingent claiming double-standards, religious zeal, reality of business, ignorant-basement-dweller, and whatever other non-argument they can to justify or detract from the issue.

      I don't buy your figures. But I do agree that there are certainly times when articles or comments are beyond the pale. Microsoft does occasionally get skewered over non-issues. I'm 100% behind calling those out. They detract from the real issues.

      Which issues are "real" is probably the point where we would disagree.

      Of course Microsoft does "bad things." The problem here is that, on Slashdot, the term "bad things" is basically defined as "Microsoft does it." It's self-fulfilling. Hell, when Microsoft gave a free 3-year warranty on Xbox 360s, somehow that was construed as a "bad thing" on Slashdot... Great example. You say "free 3-year warranty on Xbox 360."

    Since I downloaded the last MSDN library no less than 9 times and each time got a corrupted file (yes, a 1.9GB corrupted file), I would have welcomed an official MS P2P download route - one of the more useful feature of BitTorrent on large files is that each chunk is hashed, and thus has good integrity.

    Instead, there was just an MD5 checksum buried in the small print on the page, which is no help at all. The checksum validation in the install routine can detect that the archive is corrupted. Ok, it's nice to be able to tell if you got a pirate zombie MSDN library (presumably with some pages containing subtle advice on how to implement code with security holes - now we know why Windows is so insecure....) But what I really needed was a download protocol that provides for more error correction than HTTP.

    From that article that you linked:

    Peers do not need to find specific pieces in the system to complete, any subset encoded piece will suffice.

    Huh?

    Also, no peer becomes a bottleneck, since no block is more important than another.

    In bittorrent, no block is more important than any other.

    And the only bottleneck in bittorrent is when a specific block is only available from a single seed with limited bandwidth. The moment that block is uploaded to another machine the bandwidth expands.

    Finally, network bandwidth is efficiently utilized since the same information does not travel multiple times over bottleneck links.

    I'm not understanding that either. You need updates as to who has what. This will be changing constantly as different peers download different blocks.

    One possible solution is to use a heuristic that prioritizes exchanges of "locally rarest" pieces. But such local-rarest policies often fail to identify the "globally rarest" piece when peers have a limited view of the network.

    Why would you need to? All the client has to do is connect to as many peers as necessary to find each block a minimum number of times. The only time there is a problem with this is when there is only one seed with limited bandwidth.

    There is no way that a "globally rarest" will appear more often in your peer group than it does globally. This seems more of a seeder issue than a swarm issue. And it has been solved with the "super-seeder" enhancements. The seeder feeds more blocks to the guy who seems to share them the fastest.
