Comcast Outlines New Broadband Policy

Slatterz writes "US cable provider Comcast has presented its long-term solution for managing broadband traffic. The new system is set at putting to bed a minor scandal that erupted around the company when it was found that Comcast deliberately limited traffic for certain applications. The company said that under its new system, traffic will be analyzed every fifteen minutes. Users who are found to be occupying large amounts of bandwidth will be placed at a lower priority for network access behind users with less bandwidth-intensive traffic. The new system will not replace or be related to the company's earlier installment of bandwidth caps, which limited a user's data intake to 250GB per month."

      The solution then is to rate-limit at the router or TCP stack, or for applications to start being more careful about how much bandwidth they use -- just because a user has 6.0Mbps available for peak speed, doesn't mean that applications should assume that they can or should use as much of it as possible, all the time.

      P2P applications have had rate-limiting controls for a long time; it's probably about time for Skype and video-chat applications to have them too. Skype is particularly bad in this regard because it automatically defaults to the highest-quality codec that a connection supports. While this might make sense on fixed-bandwidth connections, it's not great for the majority of broadband connections, which have the capability of pushing a high peak speed, but shouldn't be expected to sustain that peak for very long. (And this isn't a bad thing or rare, either; lots of "real" internet connections are the same way. You can buy a 100Mb pipe because you occasionally need the full 100 megabits, even though you can't afford to saturate it 24/7. I'd wager most SLAed connections at .coms and .edus are like this.)

      In general, it's a pretty fair policy, especially because it only goes into effect when a neighborhood node starts to become congested. (Unlike their 250GB/mo cap and their old policy, which didn't care whether you were actually competing for resources with anyone else.) If I'm using huge amounts of bandwidth for Skype or video-chat, to the point where my neighbors are being affected even though they're just trying to check their mail and log off, they're not going to care what application I'm using. It's fundamentally no different, to anyone else in my neighborhood, if I'm taking up all the bandwidth on the upstream node with VoIP calls, Linux ISOs, or midget porn. They all have the same effect on my network neighbors, and all should get me throttled.

      What needs to happen, is applications need to get smarter about their bandwidth consumption. If a VoIP program finds itself getting throttled (increased latency), it should try dialing down its bandwidth usage -- by choosing a tighter codec, perhaps -- and seeing if the situation improves.

      Yup. As someone who usually complain about these companies not doing things neutrally, I don't really have anything to stand on this time. This is basically how it should work. It is the network neutral way of doing things. Don't analyze the type or destination, but instead just look at the traffic you are causing. If you are using more than your fair share, you get put behind the one who has used less.

      There only is so much bandwidth during primetime and to divide fairly among all users you have to do something. The system mentioned in the article is about as fair as you can get. It doesn't matter if it is video streaming or bittorrent, you shouldn't be able to use more than your fair share. Yes, high quality video streaming is probably hit, but that is because it is an incredibly wasteful type of technology, requiring high bandwidth during primetime when the user online.

      Of course, you can still complain about comcast not providing enough last mile bandwidth, having a too high oversubscription ratio, but that is a different matter. As an actual packet prioritizing scheme, this is a good one.

      when I don't need much bandwidth, they're going to give me more?

      Prioritization is not the same as giving you more bandwidth. You packets are just dispatched through their servers faster than the lower priority ones. The net effect is that you get less bandwidth when the routers are overloaded (which is VERY sensible), but when the routers are not overloaded then you will get the quicker speeds (at least, that would be a fair understanding of how it *should* work).

      The theory is that casual users are more deserving of the higher speeds and more appreciative of getting content quicker, whereas somebody who is spending 15+ minutes downloading a single thing is going to be more forgiving that it takes 4 hours instead of 2 hours to arrive.

      Personally, I think Comcast's goal is to degrade internet streaming video to the point where it matches their cable services with the "Occasional 5 Second Pause" (TM) where the service goes apeshit and becomes unusable.

      Full disclosure: I won't give Comcast a dime, and am waiting patiently for more capable internet to come to my neighborhood. Value = price + quality... and IMHO Comcast is simply a bad value.

If they can not support speeds that they are advertizing, they should not be selling them.

    Let me give you an example to illustrate my point.

    Lets say we have a service that costs $20 for the average person. But instead we charge $21. So if 1000 people pay 21$ instead of 20$ for a service, that subsidizes the 1% of people who uses $120 worth of service. Are you with me?

    So costs are: 990 people use $20 worth of service ($19800) plus 10 people use $120 worth of service ($1200) = $21000.
    While revenue is: 1000 people * $21 = $21000.

    So the low end users are subsidizing the high end users, and we 'break even'.
    That's more or less how the subsidy works in reality.

    So if we start charging those 10 people $120 directly. We can afford to knock a whole dollar off everyone else's plan? Big flipping deal. That gets lost in the noise.

    (The "noise" being price increases due to inflation, cost decreases due to modern technology, it gets used to cover some new 'feature' like anti-spam on the server, or free antivirus for subscribers, etc, etc).
