P2P Bandwidth Hogging the Net 539
zymano writes "zdnet has this article about bandwidth hogging p2p." I'm sure we'll see more rate limiting in the future and per-gig charges. The article says 60% of ISPs bandwidth is P2P, and that seems high to me, but not unrealistic. Besides, since most broadband is pretty seriously hamstringed in the upstream department, I'm not sure where they can go with this.

One afternoon the network was crawling. Our remote site was complaining the VPN was atrociously slow. The connection to the web was slow, and our firewall was blinking like mad.
I reprogrammed iptables to block a few key ports and a few subnets where the P2P master nodes live and it was like a shadow was lifted from the network.

Eh, I wouldn't go that far... if anything, I'd expect the "all-you-can-eat" rates go up, but I don't see telcos and ISPs abandoning the idea any time soon.
Additionally, if metered rates do in fact go into effect, we may be on an accelerated path to widespread deployment of wi-fi clusters in more populated areas as a means of circumnavigating the limitations.
Personally, I'm optimistic. History shows humans to be fairly resistant to various roadblocks being thrown at us, so should your prognosis come true, I'm sure we the geeks will find a way around it somehow, wi-fi or otherwise.

Unless you reinvent the medium somehow. Take telephones for instance. Would you pay metered costs on a landline phone? Probably 98% of the people pay a flat fee for local calls, yet these same people most likely pay for metered cell phone access. Why? Most likely they have no alternative. If all the phone companies in the country switched to metered local calling then you'd just have to STFU and accept it or stop making phone calls. Same with the Internet. Sure, you'll hop around carriers for a few years until that last unmetered ISP dries up and you're left with AOL/EarthLink/TimeWarner/MSN as your only ISP choice.

It's the nature of political reality and really big brand money now. And even if a few major ISPs hold out, they'll eventually go under if all the rest of the ISPs are back to making money with their restrictions and filtering efforts. Isn't the very large bandwith more or less a similar priced commodity now? Once you get far enough upstream it's roughly the same, or am I wrong on that? If it's similar, there's no way the unlimited flat rate providers could compete with the limited but significantly cheaper providers, if they are paying the same bulk rates.

I used to work on the helpdesk at a small ISP. We decided to get into ADSL, since we were losing a lot of dialup customers to high-speed (like, when I left we had half the customers we had when I started). It ended up being a lot of headaches -- dealing with the Big Telco, learning how to debug connections, figuring out how the network was set up (don't even get me started) -- but the biggest thing was dealing with people's preconceptions about bandwidth.
We went through another company for our ADSL, rather than dealing w/Big Telco, and we got charged for bandwidth -- anything over a gig per customer per month. But you can't go around saying that your customers only get a gig per month, 'cos very few other companies even mention that. So we upped it to 1Gb up, 5Gb down. The idea was that most people wouldn't even get close, and those that would, would shoot right over and pay for the rest, at $20/Gb.
For the most part, that was true: most people never did get close; the ones who went over tended to go 'way over, and we'd send 'em bills for a thousand dollars (no lie). But have you ever dealt with anyone handed a thousand-dollar bandwidth bill? My sympathies if you have.
There were two things working against us and everyone else who wants to switch to metering bandwidth:
And another thing that just occurs to me: it's really hard to explain how much a gig is, or isn't. It's a fair question from someone checking out your service: You offer x bandwidth per month, so how much is x? But it's nearly impossible to offer a real answer ("It's as long as this here piece of string"), so we offered bland platitudes ("For most people it's never an issue.").
I realize that not everyone was innocent, and we found it hard to believe that anyone could possibly use up 75Gb in a month and not know what the hell they were doing. But even if someone does understand what we were talking about, factor #1 kicks in: Shaw/Telus/Whoever doesn't charge me, so why are you?
We cut deals, of course -- better to get some than none, better to keep a customer than lose one, and the $20/Gb charge had a lot of leeway built into it. And then we tried calling people up once we noticed they were above, say, 4Gb for the month. But eventually the boss told us that if these people left -- the ones using the really insane amounts of bandwidth -- that was fine. We weren't going to get the money (no matter that they signed the agreement), and it would cost too much to either keep 'em on or pursue the matter. They'd quit, and we'd let 'em go.

I don't think those few ISPs will go under, because I don't think the other ISPs will be making much money with restrictions and filtering efforts. Then again, it all depends on skillful marketing.
The way I see it, the fewer of those unlimited ISPs are around, the more popular they will become, even if they impose otherwise unimaginable restrictions such as p2p filtering. My current ISP limits me to 10GB combined in/out / month, and charges per every gig over limit. If I could for example opt for a plan that keeps my rate the same, removes the cap but blocks all p2p ports like kaaza (sp), gnutella etc., I'd switch. Even though I don't come close to using up the bandwidth I'm given right now (at least I don't think so). It's the principle of things. I don't need to have access to p2p networks. I'm willing to give up that freedom voluntarily (as opposed to a host of others, which would be OT here). You can bet your internet that the minute my ISP raises prices and/or imposes additional port blocks to those they have in place already (25, 443) without offering me an alternative, I'll start looking for alternatives. Very quickly. And if I don't find any, I'll suck it up and go back to dial-up. Let them drive away their customers. Let them issue earning report warnings to their stockholders. Let them burn a bit. I'll come back when they change their ways.

Sure, the 10-per-second was an extreme case, but even 1/10 that result is still unacceptable for metered bandwidth. What legal responsibility does the ISP have to keep their network from hitting you with spoof data and other such unwanted/uncontrollable-from-your-end packets? From what I've seen in the agreements people sign with ISPs, none. It always seems to be a "we can charge you what we want and cut off your connection when we want and you can do nothing about it" agreement.
What about if their network is having problems somewhere away from your node that causes packet loss? You have to transfer more data from your node because their network is losing alot of it. Do they charge you for that?
Metered bandwidth is fine if they can keep control over their service. The Internet is still going through alot of development and, honestly, I've yet to find an ISP that can handle it. Whether it's over-booking broadband and cluttering the network, having little or no security policies in place for dealing with infected user machines (or infected servers... AT&*cough*), or having a generally unreliable network, "bandwidth" is a big picture that includes a hell of alot more than the upstream/downstream between me and their nearest switch.

Next, if the P2P bandwidth carried 95% legal content, would there be an issue here if a peak of 60% bandwidth was used? Is this really about the bandwidth?
Are those who share their files via P2P really bandwidth hogs, or are those who download the files the bandwidth hogs? Merely providing the files for download would produce zero bandwidth (aside from protocol overhead) otherwise.
Near the bottom of the article, they say that intra-ISP and intra-country bandwidth is the most expensive and is what must be kept under control. So what brings us all together should be regulated?

Consider this: Call up Sprint, AT&T, MCI, etc. and ask them what their price is for a DS3, including loops. You'll probably end up with something around $500/month. per Mbps. Negotiate a bit and you might get below that a bit - maybe even down around $200/mo. per Mbps if you buy enough capacity. Now, turn around and sell that same sustained Mbps/month for $35-$40 to a cable modem user.
Good business? Don't forget, you've got local transmission, switching/routing, customer support, billing, fixed costs/backoffice, equipment capital & depreciation, etc. So, for $500/mo/Mbps or so, you're making big profits on that $35/mo. customer?
Now, excuse me, but shouldn't providing BANDWIDTH be a primary focus of an ISP.
Actually, you're in the minority of broadband customers. More than 80% want fast web pages and quick email. That's not directly corrolated to bandwidth (caching servers, for instance, and high performance local network, can provide for those).
Since you're obviously not paying true bandwidth costs, and aren't in the majority, expect to pay your fair share or be pushed off of your provider's network.

Yeah, but remember this bandwidth that you, as an ISP, pay for and are assured by your backbone provider that you will be allocated at a sustained rate, is usually contended at your customer's end at a minimum of 20:1, and here in the UK you're more likely to be looking at 50:1. So your $35/month. figure gives you an income of at least $700/month if you're feeling reasonably generous towards your customers, and $1750/month on the business model in place here. That should cover your overheads quite nicely.
If you're seeing a sustained throughput anywhere near the maximum possible on your DSL line, then you're a very lucky person, and you should make hay while the sun shines, 'cos you just know that soon enough some local idiot's going to sign up and start hoovering animal porn and bangin' hard house choons, and knock your throughput for six.

The old statistic is that 2% of users make up 50% of network utilization. If true, that means metered access would result in 98% of users paying half as much, and only 2% of user going elsewhere. Personally, that sounds appealing to me, and I imagine the subscriptions would skyrocket if people heard they could get broadband (hence free their phone-line, and surf faster) for as much as dial-up.
However, it looks to me that the price of bandwidth is the least of the ISP's costs, and it's quite possible they are just using bandwidth costs as a red herring, as an excuse to force people to pay more for the same level of service they were getting before. I happen to believe that, because I've personally seen this with DSL. Verizon had one DSL plan, for $50/month, and as much bandwidth as you could utilize. Then, they decided to spin-off multiple DSL plans, and the only way to get people to pay more, was to reduce the speed of their base offering (and most people assumed it was faster because previous commericals that were nearly identical touted the faster speeds).
Meanwhile, unlike cable broadband, telco DSL has competiton from 3rd parties, and I found that Earthlink (which I had wonderful experience with) was offering unlimited bandwidth, and to top it all off, were happy to allow you to hook-up any network devices you want, including routers and multiple computers! Since I had know Earthlink to be a bit on the more expensive side as a dial-up ISP, I know they aren't curring corners, and other ISPs could be providing just as much bandwidth for less. The fact that nobody is, just shows that bandwidth is likely not a significant broadband cost for the ISP.
