How Much Broadband Usage is Too Much?

Semprini2k asks: "I just came home from work to find a letter waiting in the old snail mail box from my Broadband ISP. It has very nice titling on it: 'Notice of Acceptable Use Policy Violations' and also has an 'Abuse Ticket Number' associated with it. Has anyone else received these from their Broadband ISPs lately? Are they being overly cautious or are they working towards throwing off any users who might possible tax their network? I am trying not to be paranoid about this, but what are other people seeing and/or doing in this situation?" The "proper" bandwidth is liable to vary by region, but it would be interesting to note usage patters of people who are getting these letters versus those who aren't.

"'Oh, no!' I think to myself, 'They think I'm a spammer!!!' But further reading sheds more light on the subject:

According to our aggregate bandwidth usage records, during December 2003 your [...ISP...] account exceeded [ISP's] bandwidth usage limitations. The activity associated with your account was more than 100 times the national median. This level of activity violates [ISP's] AUP.
"I freely admit to using a lot of bandwidth. From the day Fedora Core was released via BitTorrent I have kept an active BitTorrent session going to help others get it too. So I find this a bit of a concern.

I called their toll-free number to inquire whether I could get access to their data. No, I cannot. All I can do is try to use less bandwidth and hope I do not see any more of these letters. 2 more and my service will be terminated."

    Look through their AUP and see if what you are doing is indeed a violation. I had a warning via email several months back from my (cable) ISP which claimed I was using "above average" amounts of bandwidth even though they advertised "unlimited" when I signed up years back. I replied to the supplied human-read address saying basically "An average is made of of highs and lows, right?" to which I never had a reply or a warning since. That may just be coincidence but I do generate a fair amount of traffic...

      By definition, half of their customers are using above median bandwidth. In a case with an average, one user using 10 GBs of bandwidth and nine users using 1 GB of bandwidth, the average is 1.9 GB/user. One user is above average, and the rest are below.

      Ok...no problem. We won't oversell our ADSL bandwidth at all.

      Now...about your bill. That 768/128 line is going to cost, oh...$300/month.

      Oh, yes...and I really do work for a small ISP, and our cost for our outbound bandwidth really is $500/mbps.

      Not overselling bandwidth would be the stupidest thing any ISP ever did. It would make it absolutely impossible to profit. This thing only works because at any given moment only 5% of our customers are downloading.

      In fact, a typical distribution is indeed exponential, so in real life many fewer then half their customers will be above average. The cited example is very close to reality.

      The fallacy of course lies in the implicit idea that if you get rid of all of the "above average" customers, you won't still have "above average" customers. ;-)

      Still, eliminating or significantly reducing the bandwidth used by as few as 50 or 100 people can significantly improve the performance of the system for many, many thousands of others. (Without going into details I will claim without evidence that I've seen the numbers in a real life example to back this up.) If those thousands of others are experiencing difficulties and complaining (and subsequently terminating service), guess who's gonna get it?

      It may suck if you're one of the 50 or 100 people, but if you look at it abstractly, there's nothing else an ISP can possible do. Not even increase the bandwidth, since things like Gnutella and Bittorrent can grow their bandwidth use to match the expansion. Sooner or later, the top folks need to curb their use, and for better or for worse, the ISP folks will have to be the heavies.

      FWIW, they don't necessarily enjoy it, it's just the way life is.

      Amen, jusdisgi.

      Several years ago I worked for a large (who I will leave nameless) ISP who liked to advertise their "Awesome ADSL speeds! Over a 1.5Meg a second down! Guaranteed to our router!"

      Why guaranteed only as far as their router? The router in question was a RedBack 1500 with 8000 users provisioned on it, all fed by a pair of OC3's running 145M/Sec.

      You do the math. 8000 users expecting 1.5M/sec from 290M/sec worth of pipe?

      As you so well point out, the ISP's oversell bandwidth to survive. They know that most users will only use a tiny fraction of their alocation, so most of the time they never realize how bad the situation is.

      Also, as other people point out, the ISP's have an interesting way of defining "Unlimited" to mean what they want it to mean - usually something like "Full speed for 5% of the time." Worse, for us users anyway, their business model doesn't WANT users who are savvy. They want Lemmings who'll knock off some emails, do a little surfing, and not use more than a fraction of the advertised bandwidth they're sold.

      It's the way the business works.

      You want 1.53M/sec bi-directional 24x7 that you can actually USE? Get a T1. Want a decent pipe, at a price per month less than the lease on a BMW M3? Get cable or DSL and be willing to deal with some ISP bullshit from people who don't really want your business unless you're like the other Lemmings...

    It's nice you are sharing legal software with others. Kudos to you. But don't expect them to beleive this is nothing illegal, and don't expect them to allow you to pay $49.95 or whatever for 100 times the average. I'm sure if you were 2 or 3 probably even 10 times the average, you'd be ok, because, after all it's an average. But when one or two people are sending that much traffic over their network, it's raising their cost, and eating into everyone's pocket, because the only way to recover would be to raise all subscribers prices.

    If you have another choice for a provider, check their AUP. If not, either accept the terms of the AUP and not leave Bittorrent open for the whole month, or go back to dailup.

    Remember, you don't have a right to broadband, so use it wisely.

They said that I'd been downloading about 37GB and uploaded about 20GB.

    If you cut off the top 1% of your users and sample the remaining it will still look like you should cut off another 1% since they are now the top talkers.

    I think the original poster is saying the ISP is correct to trim the unprofitable customers, not that you should constantly be trimming your top 1%. If you're running a software company and one of your clients is constantly tying up the free tech support line, you might think twice about continuing their contract...

    It's a little funny because this turns normal marketing tactics on its head. The 80/20 rule of marketing is that 20% of your customers will require 80% of your volume. This is probably roughly accurate with cable modem service. Normally, companies kill to acquire these 20% (high value customers). However, when you're operating in a fixed fee structure, these are your worst customers and (if they cost more than their incremental revenue) they should be moved out of your franchise.

    The problem with providing the carte blanche of true unlimited service is kind of infamous: Proper pricing creates a death spiral. If you raise prices to compensate for increased usage, the only folks left will be the bandwidth hogs. You'll then need to raise your prices even more, but then only the worst offenders will be left. Health Insurance works the exact same way. If prices are very high, only the sickest (most expensive customers) will remain on a plan because the price is still advantageous for them. This in turn makes cost of coverage higher. and so on...

If you think that's only worth $49.95, methinks thou doth protest too much. I mean, really, a 155Mbps OC-3 costs, what, $30k/month? That would support roughly 500 people with a sustained suck of 300kbps.

  11. Comment from an ISP... by dybdahl · · Score: 4, Insightful

    I know the rules for one ISP that provides "free traffic as long as it doesn't conflict with other terms". This very unprecise definition of "free traffic" should be understood like this:

    - They allow some customers to use extreme amounts of traffic compared to how much they pay. The turnover for some customers is as low as $1 per 1000 GByte bandwidth (!).
    - A lot of the bandwidth is free, because they are peering with other ISPs, so the customers can actually use enormous amounts of bandwidth and it doesn't cost them anything.
    - They don't want to kick customers because of bandwidth usage, because it gives a bad reputation.
    - Only those customers that use big amounts of bandwidth that costs them money will get warnings and eventually kicked.
    - It differs a lot from market to market (country to country), how many customers an ISP can kick without getting a bad reputation. It also differs, how much bandwidth costs - for instance, bandwidth is much more expensive in Germany than in Sweden and Denmark.

    I believe that many other ISPs think the same way. This means that:

    - Things like BitTorrent might be more acceptable to ISPs, if more bandwidth stays within the same ISP or to geographically close ISPs which have a higher probability of peering with the user's ISP.
    - Since users don't know who their ISPs do free peering with, it can be very difficult to determine, what amount of bandwidth that the ISP doesn't like.
