Comments on: Redundancy search: faster p2p downloads

Oh for a dumbness filter on comments. Everybody please RTFA. Yes, you can download the _same_ file from multiple torrents, even from different networks, but if you just do that by hand you’ll end up downloading most of it twice because of different chunk sizes and overlapping chunks. This technique could do that automatically and with much less overhead. And it goes much farther than that. The “S” in SET stands for Similarity, not Sameness.

Why there should always be some idiot, with egocentric attitude like X or Eriol, saying “I knew” on whatever post ? Guys, go looking for some pu****s and spend your time out of the chair… leave us alone, if you don’t like something, just shut up and change site…

I agree with z_o_z_0 (nice analogy btw), what this system is aiming to do is allow us to not only benefit from loading from other tackers containing the same exact files, but to also allow us to download from those that contain only a certain percentage of the file we need, thus greatly improving the rates at which we will ultimately receive our downloads.

For example, if I were to be searching for a file containing a particular television episode, I would not only be able to download from the trackers with that exact episodes filename, but I would also be able to download from those tackers that contain the entire season from which my episode is a part of.

Some of you have the wrong idea. It is not about two trackers having the same file. It is about one tracker having two different files. Example:

file 1: The quick brown fox ran
file 2: The brown fox jumped up

Totally different files but with quite a bit of common information. In the SET idea if you were downloading file 1 you could get “The, brown, fox” from anybody with file 1 or file 2.

Yeah I’ve been reading about this technology. Funny i think i kinda beat them to the punch, with Utorrent you can add multiple trackers to a torrent.

Example:

23 dvdscr appears on NTi and torrentleech and demonoid. Same release, you simply download each torrent, open with utorrent and it asks you if you wish to add the trackers. If the file is slightly different, like an added sample or nfo, you simply tell it NOT to download the different parts.

This takes it a step further as they are making it possible to use peers that have a similar, but not the same file. I’m very interested to see this in action and understand how it works, as there are various formats and settings when it comes to music and video files, so I’d have to assume the file would need to be the same format/bitrate for it to use it.

Unless it allows for on the fly over the net encoding, which I doubt!

Whatever if this doesn’t turn out to work. You can also boost download speed a lot just by adding more trackers to the file yourself. I do that all the time, and it works perfect.

Sounds like the idea of emule / edonkey..

That worked ! but not as fast as everyone thought !

There are tools like shareaza that combine p2p networks…

so that redundancy is already taken care of ….

lets see what future has for us

What a great idea…. Who up for the math?

X is right. I have seen this on several sites days ago. And no private site will ever allow this.

just imagine the possibility of mixing chunks… woa!
let suppose I get a chunk for a MP3 from another MP3 which share the same chunck, or a video that get a chunk from a rar file… I know that it too much dreaming, but if we can get a sharing system like that, there won’t be a prosecution for getting illegal content, because you got a file from differents chuncks, chuncks from different files… you got: a frankestein file!

how can anyone probe that the file you get is the original one? because you got it from parts of other files.

just food for tought..
