ISP Rise Against P2P Users 574

bananaendian writes "Spencer Kelly from BBC's Click program writes about the emerging backslash against high bandwidth P2P users. Apparently it has been estimates that up to one third of internet's traffic is caused by BitTorrent file-sharing program. Especially ISPs who are leasing their bandwidth by the megabyte are more inclined to resort to 'shaping your traffic' by throttling ports, setting bandwidth limits or even classifying accounts according services used. What is your ISPs policy regarding P2P and is it fair for them to put restrictions and conditions on its use."

    Unless it's spelled out in the contract, artificial restrictions should not be allowed.

    Just curious, have you ever read the service contract with your ISP? I know I haven't. My guess would be that they include a paragraph to the tune of, "If the user is doing something we don't like, we can do whatever we want about it."

    BT protocol already favours the faster seeds and peers in a swarm. Since those closest to you on the network are likely to give you the highest speeds, indirectly it already does what you ask of it.

    Since i started to use Bittorrent, it seems they put me on a "blacklist" of some sort- now whenever i seed anything for any period of time they throttle or turn off my internet for some time to "punish" me. At any time of the day, its hard to get download speeds past 300kbs and upload speeds past 100kbs. Optimum Online is the only broadband thats around here, so i just have to deal with it. When calling them to find out what exactly i was doing wrong, they told me not to seed for a long period of time. When asking at what rate i was allowed to seed before they bothered me, they were EXTREMELY reluctant to give me an exact upload ratio. Eventually one guy broke down and told me that they monitor anything over 20kbs thats been seeding for an hour! I can barely play an MMO without them shutting off my internet...

    Unlike in the states where you subscribe to broadband directly through your Incumbent telco or Cable co. The majority of people in the UK buy their broadband connection through a retail ISP who in turn buy their bandwidth through the wholesale provider namely British Telecom. This has the advantage of much greater competition so people can switch from one provider to another.

    If you don't like the service that you are getting from your ISP or Cable Company you can always switch to another ISP who offers a better service though maybe at a higher price.

    Given that DSL subscribers in the UK have recently been given the choice to upgrade to an 8Mbit service at no extra cost, an all you can eat service model is not going to be sustainable as the few bandwidth hogs will saturate their connections and leech all the bandwidth. There has to be some sort of fair use policy and this differs between the ISP's

    PlusNet has taken to use traffic shaping to effectively block all p2p traffic once a user had gone over a rather small usage limit. This has resulted in a large migration of users away from PlusNet and onto my ISP Nildram. Nildram do not traffic shape and they give a generous 50gig per month download limit which only applied during peak times. After 12am to 8am it's all you can eat. They also role your previous months unused allowance over to the next month.

    It remains to be seen if my ISP can cope with the extra demand but the point is this is a good example of the free market and capitalism. If a provider gives bad service or poor value for money their customers will simply migrate to another provider.

    It's unfortunate the people in the U.S don't have such a free market for broadband.

    Why couldn't bittorrent be modified to use HTTP for the downstream, or operate on HTTP entirely? IANABTH, but that would certainly get around any port-throttling issues.

    I can tell you have never managed a network. The problem with bittorrent is apparent even if you share your connection with 2 roommates. It is extremely aggressive, does not respect bandwidth limits, and opens a ridiculous number of connections. I have had to resort to blocking popular bittorrent ports on my linksys router just to keep the 5MBit cable connection from choking. Once the connection is close to being saturated, _nothing_ works because too many packets are getting lost or timing out.

    On an ISP scale, you _never_ want to get to the point where you are using 100% of your bandwidth, because the network will slow down to a crawl. All of your customers who play online games, have Vonage, or just browse the web will immediately start complaining, because those services simply aren't usable when the network is congested. Neither car engines nor networks are designed to run at 100% load, all the time. The exact reasons may be different, but the analogy itself is spot-on.

    I agree with you. Technology & Freedom is always one step ahead of businesses and corporations.

    One example is DVD Encryption which was cracked by a 15 year old so he can watch movies in Linux. Its going to be the same with p2p software. Users will find a way around any restrictions imposed on them.

    You think bandwidth use is high now? Wait till all p2p traffic is encrypted and then overhead will be noticeable. Who knows, maybe it won't be noticeable since bandwidth lines and router technologies are constantly being updated.

    I heard CISCO has already made routers capable of dealing with optics directly and not having to convert them before interpretation and redirection saving valuable time and obviously increasing bandwidth speeds. Cool... :)

    Actually with a large enough ISP network Bittorrent ain't all that bad, since you're likely to find many peers within the ISP. It's not local bandwidth that's scarce, it's the uplinks that are strangled because Tier-2 carriers have to pay for bandwidth to Tier-1. Here's a simplified example:

    Example 1: Let's say you're on X-National-DSL provider, and you're linked to 5 people on your torrent. If 4 of those hosts are behind the same peering point (your ISP), and that last one's stuck in Norway, then your ISP only pays for bits going to the Nordic fellow, everything else stays within their private network.

    Example 2: Let's say you have a home network of 5 PC's on a 100mbit switch, and each of those hosts is running Bittorrent. If the data you want is on one of your roommates' PCs, you will download at full speed from the local network, hell you wouldn't even need internet access, you're just using your own bandwidth to its fullest potential. On the other hand if you're getting a file from the outside world, you have to go over the DSL modem which you pay for.

    Bittorrent generates lots of traffic yes, but the only difference now is that the traffic is coming from all over the place. I don't think there's that much more file sharing going on, it's just decentralized whereas in the past things came from FTP servers and Usenet, but they used just as much aggregate bandwidth. There's no way around it, if 100 people download a 700mb ISO, there will be 70 gb uploaded and 70gb downloaded in total. The benefit of Bittorrent is that the 70gb is shared more or less equitably among the participants, instead of serving it all from one central host, which allows it to scale to thousands of clients very easily without hosing the file server.

    There is one main difference with Bittorrent, which is maximizing the total bandwidth. In my previous example, if 100 people downloaded the same file from an FTP server, the combined speed of all transfers was limited by that FTP's uplink, i.e. 10mbit, and everyone got a small slice of that bandwidth so it took longer to finish the transfer. Bittorrent does the opposite, while the initial seeder might only have 10mbit available, there are 99 other peers with anywhere from 1 to 5 mbit each, yielding an aggregate swarm speed that is several times faster than the FTP host could put out. This means the ISP has to deal with more bursty traffic, which for some puny small guys might be cost-prohibitive. It's more expensive to use up 10% of a 100mbit line, than 100% of a full 10mbit line.

    It all points to the flawed model of bandwidth pricing. In my opinion the carriers are artificially restricting the evolution of the network by prioritizing money over progress. A gigabit uplink doesn't cost significantly more than a 10mbit link, you just need a faster router. The only reason we don't have plentiful bandwidth for everyone, is because it's more profitable to artificially limit supply. The flaw in this model is that bandwidth is not a mercantile commodity like oil or produce, so why should it be priced that way ?

    Here's a question, though... Do you rate-limit P2P use, or do you rate-limit an ACCOUNT perpetually when you think P2P use is getting too high?

    I wouldn't mind one bit of P2P use (or any other high-bandwidth/quasi-perpetual bandwidth activity) is choked back, but unfortunately it seems most providers do not put intelligence into it. I've been choked by my ISP before, and when I contacted them to see what was up (and get the restriction removed) I got the following:

    A) Yes, sir, you've been flagged and your bandwidth throttled.
    B) No, we can't tell you why.
    C) No, we can't tell you what bandwidth habits trigger it.
    D) Do it two more times and we can toss you on your ass.

    Basically, they take a hardline and dumbass stance, IMHO, and are trying to fearmonger your bandwidth use as opposed to a more sensible regulation. There are plenty of P2P problems out there, but there still seem to be plenty of problems on the ISP side as well.
  • now let's assume that the p2p software that i use, uses 'hiding' into other protocols and just to cover it's real purpose, switches the cover now and then. so no connection will stay up longer than ... let's say 30 minutes ... how exactly are you going to track this down ? it is impossible for the isp to understand if i'm downloading tar.gz file of opensource projects over the net as the http headers apply, or is it actually smth else hidden in there :p.

      they can't ever filter this out, even if they could, you can always use a 'massive xorring' encryption that makes it almost impossible for them to discover what you are receiving or sending.

      and since they have no proof that you are doing anything illegal in the first place (well it may seem weird that a person reads 1.2 gbytes of news daily and receives 3.2gbytes of email, but it's not illegal) there's no legal reason to limit the bandwidth that the client has paid for.

    over & out.

    No matter how bad you think the analogy is, if you get his point it's still a good analogy.

    Dead right. The thing is, I'd already gotten the point before the analogy. The analogy just made me weep for anyone trying to use it to understand aspects of the network issues they didn't quite have a handle on already.

    The analogy helped me not at all. :>

    Throwing in my opinion as to ways in which the analogy was flawed was probably just asking to have people respond with how my points were technically flawed more than anything else. I had a niggling feeling that people would pick on the 100% utilisation point.

    The real killer for me, perhaps, was that the original poster (whose technical point was spot on, I still state!) used what could be a massively-faceted analogy (is it the mechanics we should note? is it the transport-network vs. computer network similarities? the inherent dangers to life & limb of running flat out all the time?) and unfortunately didn't state what aspects of the car analogy he was particularly pointing at.

    Anyways, it was a glorified rant. I promise to close my end of the discussion on car analogies with this: Arrrgh!
