Which network is best coded?

[eilveron_esp]

Which P2P network is best written in terms of speed, efficiency, not wasting bandwidth, scaling, etc?
I didn´t include Bittorent or DC because they´re too different.
And I´m really up for discussion here. G2 has been the most immpressive for me so far, but I´m not programer!

fastrack has swarming , but no partial filesahring
so this is not good for fast downloads especially for large files.

Edoneky has enourmous long queues.

So gnutella 2 is the best.

And WASTE of course.

[isus]

i think g2 is, bc it has message compression, and a lot of other useful features.

current downsides:
lack of users (less than winmx and kazaa and edonkey)
unreliable download system...

Gnutella2 is not the best coded p2p stack at all. It has proven to not be scalable. It's dead, fasttrack has always been the best coded, then i would say that overnet follows. Fasttrack does need PFS but besides that it is very efective and proven scalable, G2 transfers just flat out suck. You can't beat kademlia nor fasttracks routing. G2 is based on the old gnutella routing alogorithm, perhaps minor changes and G2 downloads suck. WASTE is just IM with file transfers, it has no routing and is not really a network, it is a group of a couple of people talking directly. IMO

Fast Track wins hands down....

Theres a load of others with better content such as DC, but FT is a good system with the exception of Kazaa looking/workin' kind of bloated plus the fakes and the partial CRC checking results in files being fucked up over time...

G2 is no where near the best....

Edit: I'd have to say...Napster's system....even though it was central and got shut down. When I searched Napster...I searched pretty much the WHOLE user base...Kazaa may have 6 million, but you search bits of the network....with Napster I could type in some odd ball artist who never made it past 1 or 2 LP's back in the 70's and SOMEONE would have recorded it via line in somewhere along the line...

Napster fucking owned when it came to really rare audio content.

Need anymore be said about G2? Without a decent download mechanism then there is no file sharing network. Shareaza just looks good because mike got an MFC toolkit to make it look fancy like office xp....

Like everything else in life, looks matter. If it doesn't look good 99% of all people are not going to try it. If Kazaa had been released today, no-one would use it because it has this ugly Win98 GUI. But maybe KMD 2.5 has the XP GUI?

the fastrack protocol does seem to have two serious flaws like: high file corruption rate and the way it identifies files (for instance when you search for a song, say something that delivers many results, it groups several versions of the same file with different lengths and bitrates, as if it was the same file so when you click on a file whose tag is a 4:03 mp3 at 256kbs you might actually be downloading something totaly different) these kinds of problems are imo way to serious to consider fastrack as the best protocol around.

[Foreverboard]

they are all good depending on what you use them for and the options you want out of your downloading program.

Yes, the FT netowrk is NOT reliable for file downloading. And their hashing algorithm is totally useless. It's way too easy for someone to introduce fake files and still have the file have the same MD5 hash value. The reason is simple, Kazaa/ft clients only hash the first 300K of a file, so the rest of the file is not very well protected... It's possible that the files you mentioned have the same MD5 hash (first 300K) and that could then be the reason why Kazaa groups them together. If so, then it's probably the RIAA/MPAA or whatever who's doing it.

ALL the file networks are useless when it comes to preventing file corruption.

There is no way that anyone is going to put up with hashing the file every time it has had the potential to be tampered with.

It takes several minutes to a half hour of heavy disk activity for example to hash a 700 meg movie. Any time that file is not write locked, it can be tampered with. That means if the P2P program doesn't actually keep the file open with exclusive write access it can be corrupted on purpose. That means the file cannot be moved, deleted or potentially viewed (if the viewer is coded badly to open the file requesting all access instead of just read access).

You can test your p2p program by renaming (upper case to lower case) files you are sharing while it is running. If you can do that, the files are capable of being messed with even though they are being presented as if they were verified. Be sure to check them ALL. Those that are currently being uploaded might be locked.

And don't say you can look at the write, read, create dates on the file as a tip off that the file was altered. Those can be set to any value the corruptor wants, included the values they had before he messed with them.

Do you have any compalints about Shareaza other than it looks good?

A user only needs to hash his files once, that's it, one measly time. No more, no less. Whenever the file is changed and detected by the p2p program, it will re-hash it. And it doesn't matter if the user manages to modify the file w/o the program detecting it. It will be detected later by another user. The automatic re-hashing is just a nice feature by the program, and not there to protect from someone tampering with files.

Whenever user A is trying to download a file from user B, user A will (when all/parts of the file is downloaded) verify that the file/chunk is correct. If it is not, then it will block user B, and possibly also notify all of user A's friend p2p'ers about user B. At least that's what a good p2p program should do. There's an algorithm (Tiger) that can do that. Probably a bunch of other hashing algorithms exist as well that can do the same thing.

Well DUHHHH. The point of hashing is so you don't download corrupt files. If you have to download it to check if its corrupted, you missed the whole point.

Weird you guys get unreliable downloads in gnutella2.. my downloads always finish if they have at least 3 sources. But other than g2 I like filespree's network the best. it's built very well for a udp network.
