back to article BitTorrent busts Comcast BitTorrent busting

Unhappy that Comcast is busting BitTorrents, BitTorrent has decided to bust this BitTorrent busting. On Friday, as reported by TorrentFreak, a quartet of BitTorrent developers - including three staffers at BitTorrent Inc. - proposed a new extension to the popular P2P protocol that would circumvent Comcast's self-described " …

    They could just

    Start off a conversation between two people on bittorrent with http and put the data in a jpg format for instance. Unless the filters can discern what consitutes a picture for humans which is unlikely, or they stop people uploading their holiday photos.

    The headers would take a couple of bytes, run it all over port 80 with a faked apache talking in the background for extra realism.

    Forgery has always been a crime

    Comcast's "management" procedure consists of forgery and forgery has always been a crime. A simple criminal or civil case based on this should be pursued by EFF. They can argue the merits of management all they like but management accomplished by illegal means such as forgery is still illegal.

    So now you are against Comcast's network management???

    In this article The Register sounded like they were on Comcast's side:

    Hey you are allowed to change your mind, but you have to admit to it and explain why. So is Comcast in the right or not?

    Comcast should quit while they're ahead... They're gonna lose customers this way... and they've got the whole torrent community thirsting for their blood.

    BT is the same with it ridiculous overselling of "ultra" high speed lines, only to find out that there is a contention ratio of up to 25, and that even in the quiet parts of the nights you will never reach the top speed. Bastards. Its this sort of scummy practice that makes me fully endorse absolutely screwing over their "network management" as much as possible. Can somebody invent a protocol that waits until the important parts of the day when all the Comcast board members need to do their phone calls, and video conferencing, and then only uploads BitTorrents at these times? Unencrypted BitTorrents of just random pictures of crap, so that the comcast people can see?

    Doing everything we can

    "But don't let Comcast fool you. The BitTorrent community should do everything it can to bust Comcast's BitTorrent busting."

    Step 1 should be to not even consider using this new extension. It fails to prevent anything but a very specific means of throttling, and is beaten hands down by simply implementing SSL on the server.

    I've posted reasons on TF, same username there.

    If this extension is accepted, and coded in by many admins and client devs, only to fail within 2 days, they may not take too kindly to the next extension proposal in 6 months time when come up with something else. If nobody is implementing the next fix, and the one after that, comcast gets away with it.

    If we implement SSL on the trackers instead, we get protection against the throttling this extension sets out to defeat, plus protection against other forms, and it requires no new code for the clients and just a very quick SSL cert install for the tracker.

    Later version of clients just need to add support for certificate validation then, and possibly the ability to add trusted certs (so we don't all have to buy one from verisign), to prevent man in the middle attacks. MITM is not unique to SSL either. The same thing is possible with an ISP that uses transparent proxies (if they can read your plain http page, they just broke the so called shared "secret" for this whole extension).

    whenever I have my torrent client running (even in encrypted mode) I can not open any webpages.

    close the torrent client and everything works fine after a minute.

    I don't know if Yahoo BB - Softbank is "managing" their network because every question you dare to ask as a foreigner is replied to with a "we only accept Japanese questions and do only Japanese support". Even when the mail is sent in readable Japanese but not in a perfect form.

    The only fair way to manage p2p networking is with caps and throttling AND being up front about it. I can easily see how p2p could put huge strain on an isp but if they as a buissness can't make money by giving customers unlimited access to the internet, then don't sell unlimited access. Tell the customers what they are buying and let them decide where they want to spend their bandwidth and when. If there must be throttling at peek usage hours, tell the customer and let them decide whether they want to maintain their torrent activity or postpone it so they can get some decent web surfing speed. If there must be a cap let the customer decide what is more important; 24h of voip to that new russian wife they ordered, or the latest version of every linux distro out there.

    My isp switched from unregulated bandwidth to one with a monthly cap. They sent me e-mail explaining what they were doing. I wasn't overjoyed but I knew I was using far more of the pie then most of their users and all in all it seemed fair. There website gave me statistics on my usage, and I managed my activities according.

    Ultimitly, they probably just don't like torrents because people are watching downloaded movies instead of comcast's on on demand movies.

    No effort to conceal torrent throttling here

    In Canada, Eastlink Cable openly admits to trying to "manage" torrent traffic as, I believe, do most Canadian service providers, but encryption seems to be effective so far. To me, it's shameful but unfortunately, it's a choice between crap and crappier.

    Some of their techs are total shits. I had one tell me, "We don't provide speed, we provide bandwidth." Guh. I wanted to reach through the phone and slap him. Next, while asking him to work on a problem I am having right now with my service and call me back, he said his shift had ended 2 minutes ago and basically declined to do a thing. If I was caught doing that where I worked I'd be marched out the door.

    It's no wonder to me that people are willing to take any step possible to sidestep every effort made by ISPs to limit service regardless of the reason. Competition is limited and customer service is piss-poor across the board. I'm only posting because I think the more bad press, the more chance of putting an end to this disgusting practice.

    Nice balanced article, until the last sentence.

    Let's take this game forwards 10 moves or so: BitTorrent becomes indistinguishable from, say, encrypted web traffic. ISPs aren't going to roll over and admit defeat - their business models won't support that - so all ISPs limit (or charge) any customer who generates more than a moderate amount of traffic in either direction. End of 'flat rate' tariffs for anybody other than a very light user.

    This doesn't sound much like progress!

    Surprise at "overselling"

    What you have to remember is that Telco’s and hence most ISP's have graduated from the analogue telephone exchange where, in order to maximise the return on their investment in equipment, oversubscription is standard.

    no-one is going to offer domestic users 1 to 1 contention and guaranteed speeds unless you pay a high price for it. Now it could be argued that for most domestic applications a 25-1 contention ratio is fine since most households don’t use their connection all of the time anyway and when they do it's for simple applications such as email, web browsing and uploading a few bits and bobs to mytube or facespace.

    In short the major ISP's are all struggling with lack of capacity, also with a lack of funds to increase that capacity so they will take the easy route and attempt to throttle traffic which they deem to be infringing on it's fair use or network management policies.

    It's Just business, I'm guessing here but for every 1 ComCast customer who worries about their torrents being affected by this policy there are hundreds who just don’t give a toss because they don’t use it and the policy of throttling this traffic actually improves performance for the MAJORITY of customers.

    I don’t have a business degree or the benefits of a university education but, given the choice of upsetting thousands upon thousands of people who suffer increasing degradation of service or upsetting a couple of thousand people who cant download the latest Linux distros (because, as far as I can tell that’s all torrents are ever used for?) I know what I'd be doing!

    Where is the reasoned argument icon please?

    I hope both sides loose on this one.

    1) If you are using ADSL/Cable, it's a contended service, if you are a *big* p2p-er you will impact other users of the network. Why should they suffer for your pirac^h^h^h^h^h legitimate hosting of files?

    2) Comcast are in a bit of a bind here, becuase I don't think anyone would object to them performing normal traffic shaping at peak hours to preserve 'normal services' such as web surfing etc. (not sure if this is effective against p2p, my networking is a bit rusty) but why should they fire off their own packets to mess with customers p2p software?

    Nicely put.

    It seriously pisses me off when I see my 8MBbs connection drop to a 250KBps ( or less!) crawl in peak hours knowing its mostly down to p2p-ers. Doubly pisses me off as my legitimate use of bandwidth is being hampered by file sharers.

    And lets not be under any illusions, here. Despite the whinging about legitimate uses of BitTorrent, 95% + of BT file sharers *are* sharing copyright material.

    SSL isn't the answer

    Encrypting torrents won't help. The ISPs will simply assume that anything encrypted is a p2p exchange, and will block/throttle it. All the legitimate telecommuting users of, say, SSL-encrypted email, https or VPNs will suffer as well. This is exactly what happend with Free in France a year or so ago. Lots of my colleagues who normally work from home found that they couldn't do the job they were being paid for. On my 1Mbit/s line I got 800kbit/s with unencrypted port-80 traffic, but had to resort to 24kbit/s dialup to read my work email. There was zero throughput of encrypted traffic on the ADSL line, even with a VPN configured to use port 80.

    The only solution is tariff-based. Unthrottled service up to a cap, and if you want to pass the cap you pay more. That way those who want 100% utilization pay more than those who want 1%. Seems fair to me. The only real complaint I can see about Comcast's behaviour is that they aren't being up-front about it.

    Really???? Wow, you should work for I dunno, some encyclopedia or something, you are so insightful!!!! Of course they are, but the "legitimate use" argument is being used as a legal loophole to prevent blanket bans etc.

    A while back, there were statistics about the amount of pr0n being downloaded from the net. I'm sure that hasn't changed, maybe there's a lot of pervs in your neighbourhood?

    To the Cowherd

    P2P distribution is one of the major ways communities have been able to distribute data. Yes there is Piracy but it also enables many community and open source projects to get off the ground which wouldn't have otherwise due to otherwise prohibitive hosting costs.

    As trite as it sounds it is currently the best way to put the distribution of data into the hands of the people. Looking at how much power people have gained from controlling information and so forth I don't want an elegant way of distributing it to be destroyed.

    If you want to get upset about your poorly performing internet connection complain to the ISP for over promising and under delivering. They knew damn well they couldn't provide the speeds promised and now they are handily blaming it all on the evil, data stealing filesharers.

    Why are *all* ISPs so dumb?

    If a seller has a product in limited supply, they could put a price on it and sell it by the kilo. Alternatively, they could put it out in a big room and charge a flat rate to come in and take as much as you like, and if some people look like they are taking too much then they could beat them up on the way out. (That assault probably qualifies as a criminal offence, but it's for the common good, isn't it?)

    One of these models is legal, sensible, and used in almost every industry. The other is how nearly every ISP on the planet has decided to market broadband. Why?!?

    Capped at peak hours

    I'm on virgin here in the uk, they operate a policy of only allowing 2 or 3 gigs download at peak times (4 till 9). If you go over the limit your speed drops considerably. From 20meg to 5meg i think, and stays that way for 4 hours.

    Virgin however haver hidden this nuance deep in the depths of their website, i had to call support to complain about my quarter speed line before i found out.

    Thing is, it seems fair to me as there's no real need to download more than 3 gigs in the early evening. It does suck when you go over it but it doesn't take much effort to rack up any large downloads you want to do to run after 9 or overnight.

    A bit more transparency please, if it's a reasonable policy we as consumers should be given all the facts, something about fair trading...

    NB they don't throttle torrents/uploads at all. Why should they be bothered by uploads when its less than 5% of the total bandwidth supplied!

  21. Ash

    Skirting around the real issue...

    Why is BlueYonder (Now Virgin) allowed to sell me an "Unlimited" 8Mb connection which throttles down to 2Mb after 1GB of traffic?

    Why are they allowed to sell a portion of my 8Mb of bandwidth to someone else, simply because they don't expect me to make full use of the whole 8Mb?

    Why do we keep paying them?

    Of course I know the answers to all these questions; They can do what they want because the competition does exactly the same thing, and the bodies that oversee their practises agree that it's fair.

    It's a choice of taking it up the wrong'un by a baseball bat or a bowling pin.

    Most of that is down to either excessive bandwidth throttling imposed by the ISP and/or them vastly overselling their capacity. I had similar speeds to you when I was with Pipex(Tiscali), suddenly I had enough and moved to IDnet (managed to argue with Pipex and get out of my contract too) and my speeds went back up to something more respectable.

    At the end of the day having such harsh contention on connections is a flawed system due to the nature of the business working day meaning almost everyone comes online at roughly the same "peak times" per day. Those being in the evenings and weekends, and with ADSL and Cable being "Always on" connections you shouldn't be surprised when someone does max out their usage.

    I get tired of all the "Unlimited" this and that talk from ISPs combined with the false "Up to" speeds we will never ever reach, no other industry is allowed to get away with such blatant misleading of its customers.

    Average speeds or a minimum speed we can expect at peak time please, no more "up to" nonsense, and if you Throttle me then remove the word "Unlimited" as well. Bloody ISps.

    Also remember BitTorrent has legal uses as well before you spout the Piracy argument... WoW Patches, Linux Distros the list goes on.

    @AC "SSL Isn't The Answer"

    "That way those who want 100% utilization pay more than those who want 1%." So if I have the audacity to actually want to download at 8mbps and upload at 448kbps as advertised 24/7/365 I should pay more?!

    How's that outside the advertised "8mbps download, 448kbps upload, Unlimited" service that I'm already paying for? And, come to think of it, how can using my bandwidth- which I'm paying for, remember- to the full extent that I can possibly be considered unfair (as in violation of a "Fair" use agreement)?!

    Can you imagine a car that stopped after every 1,000 miles travelled in a month "to ease traffic congestion" selling?! Can you imagine that if they didn't tell you about it but just hid it away in the fine print of your contract that the company would not be successfully sued?

    FUPs and traffic management does just mean "hey, we're overselling".

    Sidenote: Doesn't that mean that- since all P2P traffic's clearly pirated material (the RIAA told me so...)- and ISPs are knowingly letting P2P traffic pass they're aiding and abetting criminal activity?

    Re: Eponymous Cowherd

    Clearly you're an idiot who hasn't thought through what he's saying. When people get in from work and want to browse or game, do you honestly think the first thing they do is to turn on all their torrents and use up their bandwidth? Anyone who has ever downloaded files using P2P knows full well that most downloading is done either overnight, or when you're out (ie 9-5 or 7 onwards in the evenings for students I guess), but the loss of speed you're seeing is nothing to do with P2P unless your idea of peak time is not 5-9pm. This is purely down to your ISP providing a connection to you that cannot meet the requirements it suggests it can.

    I've got the cheapest of the lines, seeing as I don't do much downloading at all any more (I'm not going to rehash the fact that I download legally 99% of the time these days), and imagine what 2Mb is like when it's throttled by VM. I reformatted recently and it took hours upon hours, because they cut back my net after the first few updates. Nice.

    my connection in oz is 16 GB then flat rate of $4/GB, charged pro-rata per Mb, but they still _reserve the right to_ shape p2p between 4pm-1am if the network is saturated. It is, however, clearly in the ToS. Also, 1am-9am is counted at half the speed i.e download 2gb only 1 is counted. Also i have a fixed IP and they explicitly permit running servers on the website frontpage. <rot13>nnarg</rot13> if anyone is interested.

    @AC - Capped at peak hours

    I think that VM are one of the most communitive of the UK ISPs. If you want to find out about their AUP, then sign in to their "Customer Zone" and get details of your package. On that page will be a link to their AUP. Follow that, and you will find a link about their traffic shaping. Alternatitivly, look through their FAQ on broadband.

    If you believe it verbatim, then it is only the top 5% of users during peak hours who get traffic managed. Their peak hours are defined as 16:00 to 24:00.

    Having praised them on their openness, I find myself sceptical about what they say actually being what they do. My 8Mb/S line rarely goes over 25% of it's potential bandwidth for any traffic. My DSL router actually gives me a connection speed of about 7.4 Mb/S. This could be as a result of the upload speed of the site I am receiving from, but I have recently got a HSDPA modem which often downloads faster that my landline, even when only in 3G mode (my home is not in a "Turbo" enabled region). I suspect heavy contention, but can I get them to respond to mails asking what the contention ratio is?

    Still, I could change, and I havn't. Must say something.

    ISPs and telecos are are getting their just deserts for the classic airline trick where they deliberately oversell seats on flights as a usual percentage don't turn up. However this sometimes bites you (the customer) on the ass as they say tough and you get bumped off the flight.

    So using that analogy on an 8mb ADSL line with a contention of 50:1 all you can be guaranteed is 8/50. OOps the telecos have just oversold the flight. Before telecos invest anymore increasing speed they really should look at increasing capacity to deliver what they sold you in the first place. Ps and a message those people who have 'Free/Cheap Broadband ' and whine when it is crap - I've got some magic beans here for sale ! Also for those hardcore gamers out there who complain about ping - try going out and meeting people it's a good incentive to wash.

    "contention ratio of up to 25"

    No, try 50-1. dialup was about 25-1 to 30-1.

    For web browsing and email, dialup meant it took about the same amount of time to download a large page as it took to read it (unless it was mostly text). People often read the page as it was downloading. So your modem was on full-speed nearer half the time.

    At broadband speed, you didn't read 120x faster but your data could get through 120x faster, so your connection was idle for these low bandwidth tasks most of the time, so (despite telling you you could download movies, play games and so on [all of which took longer to download than view]) they upped the contention ratio.

    After all, since your ISP pays for the size of the connection, rather than the amount of data passed, any unused bandwidth is a lost opportunity to get another paying customer to use it.

    So, when people started using YouTube and other media sites, they had oversubscribed because they'd hoped nobody would be going back to the connection profiles they had under dialup. Rather than pay the frankly piddling cost of halving the contention ratio, they decide to throttle your connection.

    I've apparently got a 2Mbps connection. I have checked available connection speed on many occasions and I generally (~95% of the time) see less than 1Mbps. Once on Sunday I saw 1.5Mbps.

    NOTE: an OC3 with 155Mbps connection costs about £2500 a month. 50 people at 8megs is a couple of quid a month (about £2.50).

    Verizon ADSL JUST AS BAD!

    My only Torrent use is for Linux distros. I could clearly see the throttling taking place on my uploads. I kept changing the parameters to conform to their expectations/limits. They caused my seeding to time out eventually. I could watch the participation die out, one at a time.

    I could only requeue by restarting my DSL modem, which reassigned my IP address. Then I could watch it die again. I used to be able to participate (a couple of years ago), but lately they have been throttling.

    I hate to think the movie-stealers are screwing up our open-source sharing system.

    I wonder if they can tell what type of system is being used. The ones that went through were on Linux; the throttling is on the Mac. No, it can't possibly matter!

    A bit of common sense

    I'm on Virgin and a fairly heavy torrenter. Aside from Ubuntu Gibbon and Open Office (for Windows) a few months ago, everything I download is copyrighted content - usually tv shows (Lost etc) that I can't get around to watch / want to own and 'unobtainable' stuff like anime fansubs.

    I live in a shared house where there can be up to five of us trying to get on the net (for Facebook, IM, general surfing) at any one time in the evening and I do think it's unfair that their usage should be impacted by me either caning the bandwidth or putting us into the throttled zone. So I put my downloads on in the morning before I go to work or leave them on overnight. Everybody's happy.

    Some people here might complain that they're not getting the full value out of their connections, but seriously, would you expect to be able to drive a car at full speed down the motorway, all day, every day, even at rush hour?

    Personally, I'd be happy to pay by the GB - bit torrent is not an inviolable right and in most cases it's not even legal. I know that and you know that, so get real.

    Simple Answer

    Torrents are only really used to commit crime (and you all know that is true!) Simply require ISPs to block the traffic, whether it originates on their network or not.

    Also have them report any user who uses torrents to the police, failure to do so will be considered aiding and abetting.

    It's not about freedom of speech or anything. It is about theft. Pure and simple.

    Contention on dialup is a completely different thing. Dialup contention was the number of ISP modems per subscriber (well subscribers per modem), and had nothing whatsoever to do with bandwidth.

    According to Ofcom a 155MB central from BT costs £316200 annually or £26,350 monthly. 19 customers downloading at 8Mbps 24/7 constantly would fill that, making the cost per customer £1387 per month in BT charges alone.

    People don't want to pay for unlimited bandwidth

    I'm a very heavy user of bandwidth - 150Gb a month some months, I have absolutely no problems with my ISP, a mixture of VPN, ssh file transfer and BT traffic.

    The reason is I pay for the service - £75 a month, plus VAT for an 8Mb (up to) unlimited connection, with 20:1 contention on my exchange and garunteed zero contention on the ISP's end, no limits and no traffic shaping.

    The majority of the time I get the full use of my connection with little or no contention on my local circuit.

    Most people complaining are paying £9.99 a month or less, and then wondering why they get end up getting throttled.

    Sorry but you get what you pay for.

  46. b166er

    Why it's not price per GB

    Because then, they'd have to provide what they advertise; ie 8Mb/s.

    Obviously they can't do that, so they throttle under the guise of 'unfair' usage.

    If they could provide service at price/GB, then they would.

    Extreamly annoyed

    I admit that the majority of torrents are probably copyright material (even Linux distro's are copyrighted, but the license allows free distribution), and much of that will be illegal use. But those "anonymous cowards" who claim it should be completely banned need lining up and shooting. Banning torrents outright would only mean that other tools would be used. And those people who *DO* use bittorrent it for legitimate purposes (and for what it was originally used before being hijacked) would be the victims.

    And with iPlayer downloads (which are P2P) legitimise use for *SOME* commercial material.

    It will become a constant technological war between RIAA and MPAA through the ISPs to stop illegal distribution of copyright material. Let's seperate this from the bandwidth/contention debate, and encourage the ISPs to sell more realistic services that charges for use. Cap according to purchased allowance, encourage heavy users to take out higher tier packages, and invest the money in ensuring that we get what we pay for!

    Can anybody post links to credible information about traffic use statistics at any representative point on the 'net?

    You want all downloaded "pirated" content to stop, presumably so that the content that WAS pirated should make money.

    Porn is probably the biggest single product distributed over the internet (by volume: spam beats it by far as counts are concerned).

    So therefore you're asking for changes to make porn more profitable.

    (as to prove it isn't, *I* don't use it for that, one poster says it's mostly legal ISO's and Lost [which isn't much compared to linux isos] so most of the BT stuff would seem from these concrete examples to be NOT illegal in the main. Also, two of my sisters play WoW a lot and that patches up over BT. AFAIK, neither distribute pirate material over BT. Are you a massive seeder?).

    "Contention on dialup "

    The reason, AC, why dialup had a 25-to-1 contention ratio was because dialup was so slow and if your users could not connect most of the time, you lost your customer PDQ. The contention ratio was IN THAT CASE the number of modems per customer. But that's because there was no shared line.

    With packet-switched networks and shared pipes, you never *fail* to connect, so that may be a contributing factor to getting away with a 50-1 contention, since if someone complains about being slow, they'll only notice during a large download. Telling them it is their fault gives the ISP a chance at keeping their customer. All ISPs being the same crud also helps.

    Re: Simple Answer

    Well another simple answer would be that the ONLY reason to want broadband speeds is to download videos and, since the expense of legal download is so high, you can't afford enough to fill a few gigs a month (see how much it costs to fill an iPod with iTunes content...).

    Therefore anyone asking for broadband is trying to "steal" content. Anyone supplying broadband is trying to profit from someone *stealing* content. Arrest them all and lock 'em up.

    And we all have a guaranteed 56k connection with no contention.

    £1387 per month...

    ... but how many people want/need to download 2.5TB in a month, which is approx. how much you can do with 100% of 8Mb/S line.

    I pay a premium for my line at this speed, and I would like to be able to get the speed I pay for, but only in bursts, and not necessarily during the peak hours. I clearly don't get it.

    Looking at my firewall traffic graphs, it looks like during busy times, I average about 40KB/S, which equates to about 320Kb/S, which is something like 24 times slower than my theoretical maximum. And the peak (averaged out over 15 minute periods) is only 125KB/S, which equates to about 1Mb/S. Still 8 times less than I pay for.

    And now, it is very suspicious that my incoming SSH sessions hang within seconds of me starting them, which looks like VM is doing something antisocial with my traffic.

    Vuze (built on Azureus) and Bittorrent sells copyrighted Hollywood and network TV content to their users. The reason it is possible and cheaper than DVD: There is no need to run/rent a huge datacenter for distributing files over HTTP, a protocol which was NEVER designed to serve that.

    ISP Bittorrent caching

    I've said it before and I'll say it again. ISPs should be caching bittorrent traffic for the benefit of all their users. They can capture the downloaded packets anonymously, and force feed them to future requesting users of theirs.

    Let's face it - at a large ISP, users are probably downloading and uploading the same single file thousands of times, and costing a lot. A few Linux/Unix boxes and a few TBs of storage are nothing compared to the ongoing bandwidth costs. My guess is that they could reduce their traffic by up to 40% overnight with an effective system. Frankly, I think it's irresponsible of the likes of Bittorrent the company to not have included easy support for caching proxies from the start.

    Additionally, caches are almost always exempt from legal responsibility for copyright infringement because they are indiscriminate about their content, service only their customers, and are for network performance reasons.

    I'd also like to see end user dumb indiscriminate caches & proxies, to provide reasonable deniability in the event of lawsuits. As a point: Onion router users don't normally get successfully prosecuted, unless they're poorly represented or the law of the land is specifically against these kind of services, which most aren't (law enforcement loves onion routers, too!).

    Of course, this potential windfall benefit will not eventuate if most bittorrent traffic starts to be encrypted. They're shooting themselves in the foot in the long term.

    There is one proprietary BT cache that I know of, but they claim to only cache legitimate content...... I don't like the implications of such a statement, even if it is just marketing. But it shows that the technology is out there.

    "According to Ofcom a 155Mb central from BT costs £316200 annually " - this seems a bit steep, but then it is BT. So, lets max this sucker out. 155Mb/s = 19.375MB/s, so over the course of a year you can grab 19.375*3600*24*365=611,010,000 MB of data. That works out at a cost of £0.53 per gig for the ISP, assuming they can saturate their connections. If a heavy user grabs 150GB a month, then they are costing the ISP close to £80 before other business costs.

    The best traffic shaping I've been subjected to is PlusNets (not sure if its been changed since), where if you shifted more than a certain (high) amount in a month in peak hours, you were warned. If you went over again the next month, you got moved onto the "heavy users" pipe, where you still had the same contention ratio, but everyone else on the pipe liked to download too. If you spent a month under the cap, you went back up a level. Simple, easy, and relatively fair.

    See both sides

    Several years ago I was the chair of a citizens group that tried to implement Fiber service in our community. Comcast and the local Bell dumped hundreds of thousands into an effective marketing campaign that shut the initiative down.

    But, it got them off their asses and forced them to start infrastructure upgrades in the several communities involved in the effort. So I have little sympathy for the ISPs that let the infrastructure languish for generation after generation until finally forced to institute an upgrade policy because of the potential for third party competition.

    On the other hand, I've suffered at the hands of "shared bandwidth" being "hogged" by the inconsiderate users in my neighborhood. I don't care what services they are using, if they are grabbing a significant portion of the available bandwidth and monopolizing that bandwidth consistently in any given billing cycle, they should be throttled or caps should be put in place and they should be forced to pay for exceeding the cap.

    The same principle can be applied to any shared service like water and electricity. And circumventing the controls that legitimate businesses are placing on the services they provide will only result in everyone getting hit with pay as you go business models.

    But finally, I'm back in the camp with the BT crowd. Although Comcast has a right to do what they want in relation to controlling the product they provide, they should create a policy, publish the policy and enforce it consistently. If they keep trying to backdoor the process, they will continue to be forced to fight a game of one-upmanship with a very determined and capable foe.

    Regarding the new BitTorrent extension, I don't get it either. Their overall strategy has not been shared with me, but for the very reasons you have mentioned here -- both the effectiveness and the lifetime of this BitTorrent extension seem to be limited.

    And maybe THAT's the plan. Every time one of these DPI devices needs an upgrade, the Cable-Internet companies bleed. Comcast and its CableLabs cohorts now have no choice but to pony up.

    I suspect that the Cable-Internet industry has relied on DPI for so long to keep their bandwidth costs down, that to ditch it now would mean having to spend the time and unacceptable amounts of money to do the upgrades that DPI has enabled them to "delay." (heh, interesting word, isn't it).

    So by upping the anti in the war for a neutral Internet, perhaps the BitTorrent people really only intend to show them that the industry has left itself vulnerable. By making a minor change on the users end, major outlays have to be made at the ISP end.

    Hm... nice for kicking on online gaming, but you know ... gaming isn't the only thing that uses incoming connections, or UDP.

    Point in case: VPNs. Blanket dropping of all incoming connections and UDP effectively kills any VPN entry point, and well VPN endpoints actually require UDP (not TCP) traffic these days.

    Cable internet operators nationwide (this is Mexico) use NAT, so every single cable internet subscriber has a private IP (the standard class A private network range is their favorite) which means they can't play games with non-cable users (if they're hosting), and well with some recent portblocking and traffic shaping that went into effect around mid-2007, p2p is practically dead.

    Telmex's ADSL service, on the other hand, has been stable for some time now, with 1Mbit for residential (and REAL 1Mbit: 1024Kbps) while having 2Mbit and 4Mbit options for commercial lines. I get a real, public and routeable IP, no firewalls, proxies or anything else. Somehow I'd think it would be easier for other telecom giants to be able to provide something like this in the US, UK and similar places.

    Wasn't one of the major reasons behind the dot-com crash the "overexpansion" of backbones over what was really needed? I remember reading something like that, and asking "Gee, if that's true, why do I still have to pay $300/month for a DS0 link?". While most web-surfing wasn't that demanding, my Quake, Quake2 and TeamFortress needs were complaining about 400+ms pings, and the term "LPB" was fairly common. Remember that???

    Doing it in small steps may cause the ISPs to at least invest time in improving their rulesets, but this extension requires tracker admins to implement RC4 into their tracker.

    With SSL, all we have to do is let openssl and the webserver handle it. With the extension, we either have to code in our own RC4 algorithm or call in an external library/program. On a c/c++ tracker, it shouldn't be that big a deal to call in a library, but in a php tracker (think every copy of tbdev) we'd have to make calls to a program with exec() or similar (slow).

    One thing you should clarify, Robb, is that the only trackers that care about seeding/leeching ratios are private trackers used predominately by pirates.

You shouldn't have misled poor Cade about that, he's a trusting soul who admires and respects you. So be honest with him.

    I did another experiment on Comcast with BitTorrent last night, downloading a talking book version of the King James Bible I found in Mininova. After the download completed, I seeded quite successfully all night long. I started this around 8:00 PM and the pure seeding started at around Midnight and ran at 160 Kb/s.. I had no problems at all, and it's on my OGG player right now.

    @Richard Bennett, Re: Private Trackers

    Well, you can ask Cade for verification should you doubt me, but I actually said during this interview -- practically verbatim -- the words that you thought I should say. I also mentioned that the very thought of 'private trackers' seemed antithetical to file sharing. While I have little use for private trackers, they are more popular than public ones. I did not mislead Cade at all. I said those things.

    But neither you, nor I, nor Comcast are in the business of collecting royalties for copyright holders. Comcast's actions are network management to ensure a positive user experience, according to its response to the FCC. It doesn't mention copyright or piracy as any motivation. Neither Vuze, the Free Press, Comcast, or I seem to believe that copyright enforcement is relevant to this conversation. It is an issue that only seems to distract from the issue at hand. This is probably why (I'm guessing) that the subject of copyright does not appear in Cade's article -- it is a distraction from the issue.

    The issue is whether Comcast's actions affect downloads -- and, yes, they do in exactly the ways I described.

    But as for the talking KJV, while the text may be in the Public Domain, the recording is likely covered by an active mechanical copyright. I accidentally run into that myself, from time to time, with some of my downloads -- when the musical composition and arrangement are old enough to be in the Public Domain but the recorded performance is not. Again, it's not relevant and is an easy mistake to make. Mistakes are mistakes and have no nefarious intent -- I'm not accusing anybody of anything. In my case, when I figure it out, I delete the file and move on. (Since it's the Bible, maybe the performer/publisher intentionally avoided mechanically copyrighting the work -- so it might be okay after all.)

  83. Richard Bennett

    @Robb Topolski

    OK, Robb, let's be very clear about what we're saying. You seem to believe that it's impossible to seed on the Comcast network, and therefore BitTorrent downloaders are severely affected across the whole Internet. If this were true, we'd have reports from all over about how Vuze and BitTorrent, Inc. were having trouble delivering HDTV and movies to their customers, but we don't. To the contrary, Vuze said in their FCC petition that they haven't been affected by Comcast in any way.

    And moreover, Linux distros are still moving quite nicely across the net, even inside of Comcast. My last Fedora 8 download ran at 4 Mb/s the whole way to completion. So your argument is obviously lacking substance.

    In fact, there's no relationship between your MIDI seeding and the kinds of transactions that are typical of legal uses of BitTorrent. You've had trouble seeding because you don't have enough of a swarm going to reach the critical mass that BT needs to run really fast. And in fact, BT is not even the appropriate tool for the job you're trying to do. You'd have much better luck putting your music files on your free Comcast web space and letting people download them with HTTP.

    So why don't you do that?

I've also told you and the public that I cannot upload at all on Gnutella.

    Richard, stop being an ass. I've tested this. I've published my results. It's observable and reproducible (and it subsequently has been independently reproduced by the AP and the EFF and finally even admitted by both Sandvine and Comcast itself). You're the only one left -- well, you and George Ou -- who seems to be in denial and deflection mode.

    I'm done with you. I started with a fair amount of esteem for you, but I have none left. You've outlasted me, for whatever that is worth to you.

    the torrent client I use (I am not saying for what) randomizeses ports every time it oppens unless they block all ports it will work and if they did that they might as well not have a connection I know for a fact that almost every program execpt browsing uses diffrent ports and for yor infomation there are a LOT of online gamers

    just make an 'Encrypted Multicast Tunnel' and be done with it.

    it seems quite simple really if the open coder java developers were to just extend the torrent protocol and just make an 'Encrypted Multicast Tunnel' and be done with it.

    make it an experimental Azureus Multicast plug-in, tell people about it or get it included in the base package, and setup some trials , a simple small 4 to 1 ratio of peers would save masses of bandwidth and you could be happy knowing its Encypted at the same time.

    Encypted Multicast P2p tunnels are good for everyone , just make the thing.
