BitTorrent and End to End Encryption

An anonymous reader writes "As ISPs like Shaw and Rogers throttle their bandwidth to counter the growth of BitTorrent, BitTorrent developers are fighting back with end to end encryption. Oddly enough, Bram Cohen, the original brains behind BitTorrent, doesn't support this direction. Is there really anything he can do about it?"

  1. Sniffing shape-able streams by Jon+Luckey · · Score: 5, Interesting

    FTA:

    "...a wire protocol which transfers a lot of data bidirectionally and consistently looks like line noise with no header is only marginally more difficult to identify then one which uses fixed ports."

    Sounds like a call to camoflage the traffic as several pipes between peers. Not just one tcp/ip connection, but several, with a jitter function to pick which pipe is used at the moment so it does not look consistant

  2. As a Rogers customer... by abscissa · · Score: 5, Interesting

    I would like to say I am totally fucking furious that Rogers feels it can do this.

    I appriciate that Bitorrent constitutes a gargantuan proportion of network traffic. I appriciate this is a problem.

    However, the reason that I feel this is unfair, which nobody seems to have mentioned yet, is that Rogers customers are limited to 60 GB of transfer total, both ways, each month. (Unless, of course, you upgrade to the $50 account + modem rental which is 100 GB). If you exceed this limit, it's not just a matter of waiting until next month -- it is a matter of having your account shut down.

    I think it is fair to do one or the other, but not both. I once wasted three days trying to figure out why Bittorrent wasn't working, only to find out it was thanks to Rogers. This was just as they had started shaping network traffic so I had no furious posts on message boards to turn to for the origin of the problem.

    Sadly, there is no alternative to Rogers for high speed access in my area. It's Rogers or dial up.

  3. Also because by Sycraft-fu · · Score: 5, Interesting

    If Bittorrent goes out of it's way to become unthrottleable and hard to detect, it will lead to it being outright banned in many places, and the ban enforced through more draconian means.

    Like here on campus, we would prefer not to tell people what they can and can't do, however bandwidth is finite. We cannot afford to buy gigs and gigs of bandwidth just to allow people to P2P all the time, at least not without a tuition hike. The solution is to use a packet shaper, which puts P2P at a lower priority than other traffic. Usually, the line isn't maxed so P2P works as normal, however if the connection is slammed, non P2P traffic gets prefernce.

    Works very well, P2P works and is generally very fast, and other traffic doesn't get bogged.

    However, if it starts hiding from the packet shaper, things may be made a bit more compulsory like "You will make no use of Bittorrent unless it is for an approved research project. Failure to comply will result in a referal to the dean of students and possibly expulsion." Now I'd hate to see it go that way, but it will if it there's no reasonable way to keep P2P from clogging the network.

  4. I'm a Shaw BT user by 0xA · · Score: 4, Interesting

    I use Shaw so aparently I'm a "victim" of this traffic shaping. I can't figure out what everyone is so up in arms about his for. I'm not a heavy BT user but I use it to grab a couple TV shows evey week, it works fine, usually takes me a few hours to ge a BSG episode tops. I got the entire second season of the OC for my g/f in 2 days. It's not like BT doesn't work anymore, if nobody told me about this I wouldn't have noticed.

    With cable you still share a certain ammount of bandwidth with the people on your trunk, espescially on the upstream. Unfortunately some people are bandwith hogs. I see this as protecting me from the guy down the street with the warez fetish more than anything else.

    Has anyone found themselves unable to use BT because of this?

  5. Re:Encryption isn't the solution we need, or want. by Shinaku · · Score: 5, Interesting

    No.. No they're not. My ISP, TalkTalk, lied about the service they were providing me - even after I enquiered about p2p (GNUtella, Bittorrent) which they assured were totally unrestricted, they were quite happy to sign me up to a 12 month contract and totally restrict all traffic from the p2p clients. Don't worry, I've complained about a month ago and I'm intending to get out with out paying theur £70 cancellation fee. This is for users like me, who have been screwed over by greedy ISPs. And I welcome our new encripted overlords.

  6. Transfer limits per month? by blankoboy · · Score: 4, Interesting

    Wasn't the appeal of 'broadband' advertised to be 'always on, high speed, and unlimited transfers'?

    It sure seems like all you folks in North America are getting a seriousl wallet raping by the telcos/cablecos.

    Here in Japan (and I'm sure it's the same in S. Korea), we don't have any such tranfer caps. Bandwidth is also a non-issue here with 50MB ADSL and 100MB (up and down) FTTH. Also, the pricing is quite reasonable and ususally comes bundled with VOIP services. Some providers even offer TV over IP (Softbank BB).

    Japan and S.Korea are living the broadband pipedream that North America had dangled in front of it but never got (until GoogleNet shows up, seeing as they are buying all the remnants of that pipe dream - unused dark fiber).
