Have You Fought Your ISP Over Bandwidth Limits?

serutan asks: "Recently, a DC++-related mailing list I subscribe to has been buzzing with posts about letters from various ISPs in the U.S., UK, Australia and NZ, warning customers to curtail their download bandwidth usage to an 'acceptable' limit (generally 200 hours/month for three straight months). These are people who thought they signed up for unlimited access. Some of the letters hint that high bandwidth usage may imply illicit activity. All are vague on possible consequences, and nobody has mentioned actually being cut off by an ISP. One guy received an apology after talking to a supervisor about the meaning of the word 'unlimited.' Is this a growing trend? Have you received similar threats from an ISP? What was the outcome?" Of course, would it be so difficult for ISPs to stop advertising "unlimited" access, and instead include in the small (or not-so small) print exactly what the "acceptable" bandwidth usage is? If you did sign up for "unlimited" services and find yourself in this predicament, what have you done to get your bandwidth issues resolved?

    Apparently "unlimited" has been redefined w/o our knowledge. I wouldn't mind paying extra to have really "unlimited" access if that's what it took to not have to worry about this. I have "unlimited" newsgroup access which I pay extra for, and it is well-worth every penny.

      It's NOT in our best interest for "Mr. Bandwidth Hog" to pay the same amount as "Grandma Smith" who only checks her email once a day.

      Actually, it is.

      You see, when "Grandma Smith" realizes that AOL is a crappy service, she will call her nephew, a.k.a. "Mr. Bandwidth Hog", and ask him who the best ISP to use is. He will reccomend the ISP which treats him best, and she will pass that reccomendation on to her entire bridge club.

      A mom & pop that loses the geek mindshare goes out of business in under a year. Every time.

    Comcast has a limit. It is unspecified. Right now, there is a movement within the ISP to send letters to users who are using 'excessive bandwidth'. And I do agree with them, almost. Actually, not at all.

    See, the whole "it's always on" thing doesn't apply. It's NOT unlimitted. We don't know what the limit is. We aren't told. We aren't allowed to know. Customers are not allowed to know what this 'limit' is unless they go over it. Do you know why? Let me tell you why.

    Because this limit only applies to those who are in an area where there are a lot of people. If you are on a headend with very few people, you can download to your heart's content, because it just won't affect that many customers. If you try to do the same amount of activity on a node that already has too many users - UH OH! You're being excessive!

    So, by not naming a limit, they can impose one as they see fit - not by your actual usage, but by how you work as a unit within your geographic area.

    Working for Comcast (though not for much longer) gave me some interesting insights into ISP mentality.

    The issue with cable and uploads is that the FCC won't allow transmitters of more than a certain power on cable television lines w/o a license. When you upload, your cable modem is using its builtin low-power transmitter to push the data onto the wire. The cable company's central office does have an FCC license, so they can broadcast a much more powerful signal down the line to you, and in fact just broadcast everybody's downstream packets on the same channel (so in the past you could sniff the network and see anyone else's traffic, but they have added a little bit of logic to prevent that). The problem comes when multiple customers are trying to upload at the same time, each with their weak signal. In order to prevent multiple transmissions from colliding with each other, a time slicing multiplexing scheme is used. In other words, each cable modem attached to a given central office (Cable Modem Termination System, or CMTS) gets a certain time window to transmit. Quoting from How Stuff Works' article on How Cable Modems Work:

    The downstream information flows to all connected users, just like in an Ethernet network -- it's up to the individual network connection to decide whether a particular block of data is intended for it or not. On the upstream side, information is sent from the user to the CMTS -- other users don't see that data at all. The narrower upstream bandwidth is divided into slices of time, measured in milliseconds, in which users can transmit one "burst" at a time to the Internet. The division by time works well for the very short commands, queries and addresses that form the bulk of most users' traffic back to the Internet.

    A CMTS will enable as many as 1,000 users to connect to the Internet through a single 6-MHz channel. Since a single channel is capable of 30 to 40 megabits per second (Mbps) of total throughput, this means that users may see far better performance than is available with standard dial-up modems. The single channel aspect, though, can also lead to one of the issues some users experience with cable modems.

    That is why uploads with a cable modem aremore limited than downloads.

  4. Your ISP at Work by Azure+Khan · · Score: 5, Interesting

    Having seen a lot of feedback here, I'm not sure that I understand what it is that people want. Here are the things that people have said: "Don't offer speed if you can't deliver" and "don't offer unlimited if you can't deliver". Let's take a look at the way that most ISPs work, and then address those.

    Your standard ISP pays not for bandwidth, but for pipe density. T1, T3, DS3, OC3, etc. They pay for 1.5Mbps up/down 24-7 if they need it. NOw, obviously, this costs them much more a month than your 1.5Mbps download connection, by an order of magnitude of 20 or so. If you're on a dial-up service, most ISPs don't pay much to maintain infrastructure, unless they are also the phone company. It's some servers, a few banks of digi-cards, and a local dial-in number. In the case of high speed access, they generally also have to pay to maintain lines and equipment along the lines, such as repeaters and routers. A few web servers, a couple of mail servers, and you're an ISP.

    Now, here's where the issue comes in. Normally, an ISP expects that some people will use high-speed very sparingly, probably depending on it for a few small critical tasks and the rest is email. And then they know there will be a few gamers and downloader making up some slack. This is expected by your broadband ISPs.

    The problem comes in when you have someone who demands to use their connection for 1.5Mbps, all day, every day. The same connection, bursting, might serve six or 7 heavy usage customers, or 40 light usage customers, but now you have one single customer, attempting to consume $500 worth of download bandwidth for $50.

    Obviously, there should be some sort of common sense applied here. Capping the top speed lower would be a poor idea, because those who download the occasional large file or movie trailer or whatnot enjoy access to the full speed. Changing the access hours seems silly, since some people play games for hours a day but never come close to consuming full bandwidth. Does it seem right to penalize this MAJORITY of the customers because a very small percentage of customers who seem to be of the opinion that if you have a 1.5Mbps connection, you MUST use all of it. If you gave them more bandwidth, they would simply find something else to do with it, not content unless they are pushing their connection as hard as possible, obviously lacking any idea of the economics behind it all.

    Some have said that hard limits should be imposed in the contratct. This makes me sad, because it means that you are telling the company that they cannot trust their users, that they cannot use reasonable judgement, or expect that from you. Sometimes, you might have customers who never go over the limit, but might have a school project one month that pushes their usage up high once. As an ISP, I'd prefer to be able to use my discretion in this situation rather than hear the "told you so" of users crying about "lax enforcement of rule".

    DISCLAIMER: I work for a mid-sized ISP.
