Interview Responses From BitTorrent's Bram Cohen
from the download-popular-ISOs-without-waiting dept.
1) Bit-Torrent browsing... by CashCarSTAR
Has any effort/thought been put towards bit torrent page distribution?
Specifically, a way that one can use BT to mirror webpages. A way to get around the /. effect, and as well would work wonders the next emergency that comes out (see 9/11).
Bram:
Images in web pages are very small and require very low latency. BitTorrent is designed for much larger files, which download on the order of minutes or hours rather than seconds. BitTorrent uses the significant amount of time those downloads take to try out and compare different connections. This process has inherent latencies which make it unsuitable for images on web pages.
Certainly it would beis possible on paper to dramatically reduce the cost of hosting an ordinary web site using peer transfers, but the logistical problems of handling many small files at low latency have yet to be solved, and will probably require a protocol which looks significantly different from BitTorrent.
2) Forward successful download stats to originators... by gsfprez
Many freeware/shareware folks like to keep download stats for marketing purposes, so P2P software and mirrors really irk them....
In order to foster more love from freeware/shareware distributors, could BitTorrent be made to inform the end user (me) that BitTorrent was going to send a "notice of download" (not including any personal information, such as an IP, etc) upon sucessful download (that I could preview before sending of course)?
If *I* was Warner Bros, and eveyone offered to distribute and pay for all the bandwidth for the next version of the Animatrix, while I still got to see download statistics, i'm not sure I'd even would need to provide a direct link to the 150 meg QuickTime files.
With this kind of feedback mechanism, the software/media providers get all the love - download stats, far far far less bandwidth used - and we get all the goodness - their free movies, software, freeware, data, etc. Its the ultimate mirror.
Or am i missing something?
Bram:
I'm happy to report that you are, in fact, missing something. Clients report very detailed statistics to the BitTorrent tracker, including the number of complete downloads and the total amount each peer uploaded and downloaded. If you host a file using your own tracker, all of this data is readily accessible, the same as if you hosted it via http.
By the way, many people find out about tracker statistics reporting and falsely think that hacking their client to exaggerate their upload rate will increase download speeds. Clients actually decide who to upload to based strictly on the transfer rates they experience directly; Tracker statistics are never even sent to them.
3) Comparison to other P2P... by jfmiller
As far as I can tell the genius of BitTorrent is allowing peers who themselves do not yet have a complete file to share the parts they do. With all dew respect to the effort taken, the rest is just functional glue that allows the system to work as it should.
The eDonkey protocol used the same basic premise. How is BitTorrent different to it and other P2P protocols and why did you make that choice?
Bram:
That 'functional glue' is extraordinarily difficult to get to work well. Ever-changing network conditions and very high rates of peers disconnecting produce a very thorny logistical problem. Most existing swarming implementations don't even manage to fully utilize all the upload capacity available to them.
That said, there are other decent swarming implementations. For example, the one in eDonkey is quite serviceable, and Furthurnet's works okay as well. BitTorrent handles the little details of file transfer better than all of the others, but if that were the only difference its advantage would be relatively minor and subtle.
What sets BitTorrent apart is its very robust technique for rewarding specifically the peers which upload the most, known as leech resistance. On the highest level, this prevents a long-term meltdown of the system from being caused by people running leeching clients. It also causes upload and download rates to be somewhat correlated, so peers on good pipes get decent download rates, which increases general good feeling about how the system behaves. Overnet, the follow-on to eDonkey, may start using BitTorrent's peer protocol in the future specifically for the leech resistance properties.
By the way, people sometimes run clients hacked to not upload at all and still experience good download rates. Usually this is because they're downloading a file which has been available for a while and there are many clients which have finished downloading but been left running, so there's plenty of excess bandwidth to go around. Not uploading in a swarm which is still ramping up is generally ruinous for download rates.
4) Improvements... by BJH
Bram,
Do you have any plans for improvements to BitTorrent to improve some of its (few) weaknesses, such as searching for torrent files, bandwidth usage by trackers and inability to download if the tracker goes off the air?
Bram:
I have no plans to add search functionality, since that can be handled at a higher layer, such as google, and finding content via links is considerably more versatile and widespread than keyword searching anyway.
Bandwidth used by the tracker is currently around 1/1000 the total amount of bandwidth used. With some tweaking, I can get that down to around 1/10,000. Going lower than that would require sacrificing the tracker's ability to collect statistics, since those get significant at that scale.
Relying on a single tracker is really no different than relying on a single web site. Any well-colocated machine is plenty reliable enough, and if you really need failover you can do it at the DNS level.
5) Impending doom... by damu4a) Re: Improvements... by ichimunkiI would like to refine this question because I have some specific nits that I'd like to pick: why doesn't the client/server open a single port and listen on that instead of opening a new port for each file? Second, why don't the peers maintain and share information about other peers once the download has started-- going through the central tracker provides a central point of failure. Wouldn't decentralizing allow for a .torrent file to have a list of seeds, and then each of the seeds would be able to share information about peers, eliminating the need for a tracker altoghether?
Bram:
Single port has been high on my list of things to do for a while now but keeps getting put off as more immediate concerns pop up. It mostly hasn't been done yet for a highly technical reason. The way BitTorrent currently shuts down is with a hack where the entire event loop is terminated; To support multiple downloads a cleaner technique which only stopped events and sockets related to a particular download which one of them terminates would be necessary. This is reasonably straightforward to implement, but requires a lot of surgery.
By the way, my mail load has made getting actual development done rather difficult as of late. I'm hoping to offset this with contributions from other developers. While there's been plenty of interest in contributing, and a significant amount of contribution to the tracker, to date noone other than me has made any significant changes to the core download functionality.
If anyone really wants to make a significant development contribution to BitTorrent, you should read over the codebase enough to understand it all (the irc channel can be helpful with this) then ask me what's on the to do list. I suggest you do not start implementing your own BitTorrent client. There are already several of those being worked on, and they're all very far from being as mature as the main line client. What's really needed is more development on the main branch.
Are you taking any precautions for your clash with the RIAA/MPAA?
Bram:
I don't expect to run into any legal trouble. BitTorrent can be used for any kind of content, and several web sites have used it for their own files. Also, all the etree usage (live show recordings of bands which permit it) is completely legal. BitTorrent's total bandwith usage would be quite substantial even if the etree distributions were all it was used for.
6) Future Considerations... by pgrote
Do you feel that BitTorrent's core functionality can one day be integrated in the operating system as a file system? The ability to share files among disparate systems in remote locations can be seen as extension of what was started with HTML, et. al.
Bram:
No. BitTorrent's API is one of starting a download and later being notified that the whole download is complete. File system APIs very specifically involve open(), seek(), read() and write(), which are completely different and wholly incompatible with the way BitTorrent works.
The same is true of http by the way. Attempting to make certain protocols act like local file file system access is kludgy at best, both as a literal concept and as a metaphor.
7) Panhandling for internet dollars... by Matey-O
You've got a paypal dontation button to help compensate you for your non-trivial expenditure of time...how well is that working? Is it an adequate revenue stream, or just enough for a pizza or two?
Bram:
So far, more than a pizza, but less than a living. The donations definitely help though.
8) Re: most obvious question... by Noksagt
...what do you think of what people have done with what you have created. I'm sure you might be sick of people asking you how to obtain a torrent for the latest movie, but are you troubled that it is being used for copyright infringement? Pleased? Apathetic?
Do you wish that it was used more for distributing legal ISOs and other files? If so, do you believe you should promote it more for this purpose or promote development of tools to push it in this direction (perhaps automatic creation of torrents on a successful build, etc.).
Bram:
I'm amused mostly. I find humans highly entertaining.
My attempts to promote BitTorrent for any specific purpose basically failed. It's grown almost entirely through guerilla marketing. That said, I'm hoping that in the future BitTorrent starts being used directly by content producers to distribute their own works.
9) Success... by pgrote
BitTorrent has seen a wide array of usage since it debuted. Many have been surprising and it has caught the fire that makes sofwtare a success. How do you personally measure the success of BitTorrent? Has it achieved the goals you first set?
Bram:
I generally measure software success by how many machines it's deployed on. In that sense BitTorrent has done very well, but it will probably become much more widespread as publishers make their content available using it. My current hope is that BitTorrent will one day be installed on almost all end user machines.
10) Commercial Interest... by Noksagt
I think that bittorrent can be of significant commercial interest. It might be used for software updates for instance. Have you pursued this path or have companies approached you? I certainly hope you'd keep a free version available, but a more feature-rich version would surely land you a great deal of money with the right pitch.
Bram:
So far there hasn't been much commercial interest, but I expect that to change now that large deployments have proven the technology so dramatically.
Starting a business is very tempting. BitTorrent has the potential to create such incredible amounts of value that if I manage to make even a tiny fraction of that I could do very well.

The 'open source' crowd - which I'm a part of, mostly out of paranoia - recognizes that software can be worth paying for even if it's GPL'd. For example, I've purchased copy after copy of SuSe and Redhat distributions, even though there's absolutely no reason I would *have* to do this (and as a programmer, I don't need support, so I have no incentive to purchase in order to get support). Why? In part out of laziness (box, manuals, CDs) and in part because I think the product is worth money.
Being something of an optimist, I think most people in this arena are 'open source' and not 'free software'. Which means that Bram might very well make a bundle. In fact, whether or not he did make a bundle would go a long way to proving or disproving my belief.

Other languages cover some of these requirements too, of course. But Python is a great choice.
As for reducing the slashdot effect using a distributed mechanism, I'd like to see something like this: Slashdot runs a BitTorrent server and provides a "package" for every story. Users run a small local HTTP server that fetches web pages from Slashdot story packages, downloaded via BitTorrent. Slashdot lets users set a preference that converts all front page URLs to fetch from the local HTTP server instead of the real site.
The net effect is Slashdot provides a "cache" without actually using up bandwidth. We wouldn't even have to change the BitTorrent protocol. Slashdotters unite!

Python can also be fairly well optimized; I have a strong suspicion that the slashdotting of trackers is more a bandwidth issue than a processing capacity issue. It's also quite possible (caveat: I haven't read the code yet) that the internal structure placed a higher priority on readability and maintainability than on processing efficiency - I know I've written server applications using that approach, because I'd rather spend an extra $500 on hardware upgrades if more power is needed than an extra $5000 later on additional maintenance, debugging and testing.
Finally, on the issue of speed: a lot of what a tracker does involves managing lists, hash tables, etc. - the type of thing that's built into Python and highly-optimized. It's like someone's discovery when VB5 or VB6 came out that a VB program was faster at some tasks than a corresponding C++ program, because all the processing was being done using very heavily optimized builtins - if you're running a relatively inefficient scripting language but using it to call highly-optimized native code, you may not see the performance degradation that you might expect.

this way the first few people on the thing would be getting it from the corporate client, then after that from other peers, but then when the file becomes unpopular, people would then basically be getting it from the corporate client again.
This would a little improvement. Though this may just show my ignorance of how bittorrent works as well. Currently I download some files using bittorrent (wolfenstein enemy territories) but when all the seeds go away it can cause issues.
So basically make it so that there is a relatively permanent seed, and he is always requested from LAST. that way if the file is popular the site doesnt have to worry about losing bandwidth.
also, stats tracking should be "ramped up" a little, to where someone would have to register to use the torrents on a specific site, this way the tracking per user could be used. Now this wouldnt interfere with anyones right to privacy, but could be used as a "bonus" system, to provide incentive to keep the torrent open. IE the more you upload the more "credit" you are given. If you think of it in slashdot subscriber terms, perhaps people that have a high "credit" (ie they leave their client open after being finished) would get earlier access to files. maybe have a 3 teir file access. top teir (high uploaders) would get the file as soon as it was served. second teir would get at it 20 minutes later, and 3rd teir get it 45 minutes to an hour later.
this would allow sites to reward those that are high quality users, and maybe allow them to track site benefits based on participation.
maybe call it "sitetorrent" or such.

I think a "startup" nowadays needs to go ahead and have a sellable software product in hand before expecting to go anywhere, much as a startup free software product needs to have something that does usable work before it will attract a developer community.
The only thing that would concern me about this business model is that bandwidth prices are kind of artificially inflated right now because of really crappy leadership by our Federal government. If any FCC administration ever figured out what they were doing, or suddenly had an attack of ethics and remembered that they're supposed to server the people rather then corporate interests, the bandwidth situation could significantly improve, which would lower (albiet not eliminate) the need for BitTorrent technology at the corporate level. There may be a relatively narrow window where this sort of thing is economically viable (as opposed to useful; they are not the same thing at all!). Still, said "relatively narrow window" in all likelihood is at least three or four years (I can't imagine the bandwidth situation being sorted out on a large scale in any lesser time period) and you can still make a respectable amount of money in that time, plus you have that time to refine the product into something that may be able to continue to be usable even after market conditions change.

I don't think he gets it. First, we've already discussed the virtues/sins of DNS round-robin. But basically, when DNS round-robin doesn't solve your problem, you have to go to Big-IP. Which means 'free' tracker sites will need complex setup for failover/redundancy.
If the Tracker itself, had this built in, i propose it could do it more efficently, and with less setup hassle. Imagine being able to setup a mirror by simply having the admin place your new "cluster-able" tracker IP:Port on an approved mirror list. The main tracker could refer clients to a mirror after behind-the-scenes communication to determine which mirror has least load.
A step below this, but better than DNS round-robin, would be to give the client an array of tracker addresses. This is better than DNS because you don't get the stalled server mixed with cached DNS record causing inaccessibility. The clients could try connections randomly to the servers in the array, and prevent cached dns records for altering distribution.
