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.

      From: "Livingood, Jason"
      Subject: Clarifying Misconceptions of the New Comcast Congestion Mgmt Syste

      Hi Dave

      I wanted to try to clear up a misconception about how the new Comcast congestion management system works. I believe we have both heard people complain that they fear that they will be unable to use their provisioned speeds during off-peak hours, for example, or at all times of the day, or that users are somehow throttled to a set speed. Neither of these two things are correct. Part of the problem appears to be confusion over how a user's traffic enters a lower priority QoS state, so I hope to clarify that here

      In order for any traffic to be placed in a lower priority state, there must first be relatively high utilization on a given CMTS port. A CMTS port is an upstream or downstream link, or interface, on the CMTS in our network. The CMTS is basically an access network router, with HFC interfaces on the subscriber side, and GigE interfaces on the WAN/Internet side. Today, on average, about 275 cable modems share the same downstream port, and about 100 cable modems share the same upstream port (see page 5 of Attachment B of our Future Practices filing with the FCC, available at http://downloads.comcast.net/docs/Attachment_B_Future_Practices.pdf). We define a utilization threshold for downstream and upstream separately. For downstream traffic, a port must average over 80% utilization for 15 minutes or more. For upstream traffic, a port must average over 70% utilization for 15 minutes or more

      When one of these threshold conditions has been met, we consider that individual port (not all ports on the CMTS) to be in a so-called Near Congestion State. This simply means that the pattern of usage is predictive of that network port approaching a point of high utilization, where congestion could soon occur. Then, and only then, do we search the most recent 15 minutes of user traffic on that specific port, in order to determine if a user has consumed more that 70% of their provisioned speed for greater than 15 minutes. By provisioned speed, we mean the "up to" or "burst to" speed of their service tier. This is typically something like (1) 8Mbps downstream / 2Mbps upstream or (2) 6Mbps downstream / 1Mbps upstream

      So how does this work in action? Let's say that a downstream port has been at 85% utilization for more than 15 minutes. That specific downstream port is identified as being in a Near Congestion State since it exceeded an average of 80% over that time. We then look at the downstream usage of the ~275 cable modems using that downstream port. That port has a mix of users that have been provisioned either 8Mbps or 6Mbps, so 70% of their provisioned speed would be either 5.6Mbps or 4.2Mbps, respectively. So let's use the example of a user with 8Mbps/2Mbps service on this port. In order for their traffic to be marked with a lower priority on this downstream port, they must be consuming 5.6Mbps in the downstream direction for 15 minutes or more, while said port is highly utilized

      Once that condition has been met, that user's downstream traffic is now tagged with the lower priority QoS level. This will have *no* effect whatsoever on the traffic of that user, until such time as an actual congestion moment subsequently occurs (IF it even occurs). Should congestion subsequently occur, traffic with a higher priority is handled first, followed by lower priority (and this is not a throttle to X speed)

      I hope this helps. You can others can feel free to contact me directly if you have any questions

      So yes, people watching a lot of YouTube will get throttled. It's even possible that people watching a lot of YouTube will even be throttled before people downloading warez, if the people downloading warez keep their bandwidth under control.

For them to determine what content is legal and what's illegal would require intrusive deep-packet inspection, and maybe even blocking encrypted traffic or performing MITMs to get around it. It's far better not to go there and to just count packets.

      Plus, it doesn't matter to your neighbors what, exactly, you're doing with the bandwidth -- if you're hogging the upstream to the point where there's contention, it's irrelevant what happens to be inside your bits, just that there's too many of them.

      Well, the interesting thing to consider is that there are situations where a node might get congested, but nobody would get throttled. I'd hope that if that situation occurs, Comcast will realize it's a sign that the node is oversubscribed and break it up.

      The QoS deprioritization only kicks in if the whole node is "Near Congestion" (to use their term), and if an individual user is close to pegging the needle for 15+ minutes. It's entirely possible that a node might become congested without meeting the second criteria.

      E.g.: Lets say a node has 300 users connected, and it has a 1Gb/s backhaul. (We'll imagine that all the traffic is either symmetric, or only deal with one direction, just for clarity.) Users only get throttled when they're at 70% of their allotted peak. If each of those 300 users has a 6Mb/s plan, they could all be holding steady just under 70% -- low enough to avoid throttling -- but still saturate the node. In fact, they only have to each be at around 56% utilization for full saturation of the upstream link.

      If Comcast sticks to its word about the throttling cutoffs -- and I admit that coming from Comcast that may be a bit too much to expect -- they won't be able to use it to stave off equipment upgrades forever, in the face of new services that cause large numbers of users to start sucking down bits. If everyone in the neighborhood decides to watch IPTV or do video chat at once, there's going to be contention, and the throttling setup they've created won't do a thing about it.

    I can't speak for everyone, but I do bioinformatics/computational biology and often telecommute when consulting or to continue the days work at home when deadlines are tight. Depending on the project or analysis task, having local copies of public scientific databases is very useful (eg. http://www.ncbi.nlm.nih.gov/Database/). These databases are rather large and are growing rapidly. Since terabyte drives have become affordable, it's become feasible to maintain up-to-date personal copies at home rather than accessing them via NFS at work or working with representative subsets.

    Perfectly legal, legitimate and probably more useful to society than streaming HD content. This is the kind of stuff we used the internet for back before it hit the bigtime, so as legitimate a use of the internet as what people now consider "normal use" (web browsing, shopping, watching video, streaming music, and yes I do those too).

    Uh, let's see:

      - Downloading F/OSS software?
      - hulu.com?
      - Various TV networks?
      - Netflix?
      - VOIP?

    Face it: (IMHO) Comcast is afraid of streaming video sites, and are using P2P as an excuse to curb competition. They do not want to happen to them what happened to land line telephone companies when cellular and VOIP took off.

    Then shouldn't the people who use 10 or 15 a year pay considerably less than they are now?

    After all, the only reason pricing is at this point is because they reasoned that the people using the service at only 5% capacity would effectively subsidized the others who use it at 100% capacity.

    If you're now making those who would use it at 100% capacity pay more for service, shouldn't those who are only using a fraction of the network capacity get a major discount to their connectivity?

    Perhaps a bit less, but not necessarily considerably less. (After all, there is considerable fixed overhead to a DSL line on top of the bandwidth, those 5% bandwidth users consume telephone support, need their "modems" fixed, have line trouble, etc at the same rate as the 100% users.)

    After all, the only reason pricing is at this point is because they reasoned that the people using the service at only 5% capacity would effectively subsidized the others who use it at 100% capacity.

    That's true to a point, but its a gross oversimplification.

    If you're now making those who would use it at 100% capacity pay more for service, shouldn't those who are only using a fraction of the network capacity get a major discount to their connectivity?

    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).

    He's not talking about syncing up a 15gig home directory. He's talking about producing 230gigs of data per month in deltas to whatever he's generating (I hope he's using rsync and not something naive).

    Backing up 230 gigs/month is certainly business class usage. If "business" isn't a good adjective use "large" if you want. You don't have to be making money to need "business" features.

    How is me wanting what I was sold unreasonable?

    You were sold a resedential service with residential terms and conditions.

    Your terms include:

    • The Service is for personal and non-commercial residential use only. Therefore, Comcast reserves the right to suspend or terminate Service accounts where bandwidth consumption is not characteristic of a typical residential user of the Service as determined by the company in its sole discretion. Common activities that may cause excessive bandwidth consumption in violation of this Policy include, but are not limited to, numerous or continuous bulk transfers of files and other high capacity traffic

    So you bought a product that bulk transfers of files may be restricted. Why are you complaining when Comcast are giving you exactly what you bought? As others have said, they probably also sell products more suited to your needs.

    The system (based on everything I've read) does not care, or try to detect, the contents of your packets.* It doesn't care whether what you're downloading is legal or not.

    This is exactly as it should be, since it doesn't matter to other people on the local node what you're doing, only that you're hogging bandwidth. Legal movies, illegal movies, videoconferencing, a totally opaque VPN connection ... it doesn't matter. They all have the same effect on other users of the network, and should all be treated exactly the same way.

    * Or so they claim. Some people have noted that the hardware they're using comes from a company most noted for its sophisticated and purpose-built DPI products, which seems like a bit of an odd choice of vendor for something that's really quite simple. I don't have a dog in that fight, but I'm taking them at face value for now.
