Neutral Net Needs Twice the Bandwidth of Tiered 271

Posted by Zonk
from the we'll-need-to-craft-fewer-packets-overall dept.
berberine writes with a link to Ars Technica, straight to an article discussing the differences between a net neutral internet and one that supports tiers of content. As you might imagine, our neutral internet is far more bandwidth-intensive; AT&T estimates it might require as much as twice the bandwidth of a tiered internet. From the article: "Corporate sponsorship of research doesn't automatically invalidate that research; what's needed is a close look at the actual results to determine if they were done correctly. According to David Isenberg, a long-time industry insider and proponent of 'dumb' (neutral) networks, the research itself is fine. In his view, it's simply obvious that a dumb network will require more peak capacity than a managed one. But extending that banal observation to make the claim that running a managed network is cheaper is, to Isenberg, not at all intuitive. For one thing, doubling the peak volume of a network does not mean spending twice as much money as it cost to build the original network."

      Even then, let's suppose you were willing to accept a tiered Internet. How you tier makes a difference in whether it is maximally efficient for a given application. The reason we used managed networks in a corporate environment is because of corporate priorities -- financial transactions are more important than e-mail, so we segment off financial transactions and then give those transactions that must run over the same network as e-mail a higher priority over the e-mail, for instance.

      The question is: How do we decide what traffic is more important on the Internet? Who pays? Who pays more? That's stupid. The benefits of a a free and open Internet far outweigh the inefficiencies of working with a basically unmanaged network. (Not that the Internet actually is completely unmanaged -- that's just not true. ISPs shape traffic on their own networks to improve customer connectivity to mail or webservers within the ISP's own network). The point of the Internet is to have a network where anything is possible. Tier it off and you'll make it about as useful as the television networks.

      To put it differently, unmanaged traffic where the drivers get to decide which road they use themselves is less efficient than a traffic net where a central authority dictates to you which highway you're allowed to take. Of course an unmanaged net needs more throughput capacity overall, but in exchange the traffic doesn't require micromanaging. Part of why highways and trucks beat out rail service is because of that flexibility, of not being at the mercy of the switching stations and schedules.

      Or consider an irrigation network with multiple sources and multiple outlets. You could either build all the pipes so that any of them could deliver maximum capacity, or have workers actively controlling the valves to distribute the water across the entire net so that one side doesn't overload. The latter solution doesn't require as robust a pipe, but requires a more complex valve system and somebody controlling it.

        That's a horrible analogy - It just doesn't hold up. The trains are actually far more efficient than highways as a system, but since the U.S. spends more on cleaning roadkill of the highways than total funding for Amtrak they don't have enough staff or working trains so things get off schedule which causes the entire system to break. Just because the U.S. can't manage a switched system doesn't mean it is bad... try telling someone in France that the highway is faster and more efficient than the train!

        Unmanaged networks are inefficient and pointless. There is no damage in routing things to avoid network congestion, but tiered networks are bad too. A tiered network is like a toll road that has restricted carpool type lanes, but the number of passengers doesn't matter - how much you pay in tolls does.

          Trains and highway have different efficiencies, though. A train is an excellent way to move a lot of something a long distance. Highways are excellent for non-linear, lowest time transit, or local distribution. I couldn't take a train to my home, for example. I would need to take a taxi, bus, or personal car to get there from the train station. I couldn't take a train to work, since the time lost getting to the train, getting on the train, getting off the train, and getting from the station to work far exceeds the travel time to just drive.

          Going between cities is where trains are the most useful. Moving about inside, or around, a city is where the highways are most needed. Rural areas, and there a lot of them in most every country, still need highways nearly all travel.

          The unmanaged system of highways allows for all of the same things as trains, though less efficiently, but also allows for *substantially* more freedom of movement and independence of travel time. The right answer, as it always has been, is to use both.

          BTW - it isn't just Amtrak that has problems in the US. Nearly all public transit systems are doing their best to approach complete uselessness. It is still faster and less expensive, for me to own, insure, and operate a car where I live than it is to use public transit. This is in metrowest Massachusetts, for reference. NYC is better, but the subway is still no picnic, and light rail can be hell there, too, but it's still a lot better than driving, usually.

          For what it's worth, if rail was the better option in the US, business would use it more. As it turns out, you get more for your money by moving things around with trucks and planes. Transit times are much lower, and you can deal with changes in volume and the need to reroute things much more easily.

      I even agree with the sentiment, but the study incorrectly implied or stated that doubling the peak capacity would double the costs. Even if that were true, not doubling the peak capacity would _not_ halve the "speed" of the internet. For what it's worth here's a selected quote from Ars quoting Isenberg, commenting on the study.

      ...
      doubling the peak volume of a network does not mean spending twice as much money as it cost to build the original network. "The failure of the authors to extend the conclusions from capacity to raw costs of capacity is deliberately misleading," Isenberg says, "especially when the researchers invoked 'economic viability' and 'cost of capacity' in their introduction to the work." ...
      According to Isenberg, the cheapest and best alternative is simply to build out dumb capacity: to "overprovision" by as much as 100 percent.

      The study is flawed from a number of perspectives. First, as you mention, the current costs to consumers vastly exceed the costs to provide this mythical doubling in bandwidth. Secondly, network neutrality (to me) means that everyone gets the same experience and access as everyone else. This means that if you implement user-neutral traffic management (packet dropping schemes to minimize retransmits, throttling streams at congested points, fair service to ensure no connection is stagnant, smarter routing algorithms that avoid segments that are basically dead in the water) and user-neutral methods of improving data distribution (web caches, multicasting, SRM) then you gain virtually all of the benefits AT&T claim for their non-neutral system - and more besides - without harming a single user.

      The above remedies would give all of the smoothing at peak times on heavily loaded routers, but in a manner that is entirely equitable and - get this - doesn't actually reduce the service provided to anyone. The peaks that kill the backbones are not particularly long-lived and contain a vast number of unnecessary retransmits, inflating the traffic levels. Schemes already exist that can potentially halve the retransmits and diffuse the load over just enough time that it can be handled. Other schemes already exist that can eliminate unnecessary repeat transmissions from source, massively reducing the load on the most burdened segments.

      None of these require that any user be given priority or special privileges. None of these require that neutrality be compromised. Yet none of these require that either services or end-users experience any detectable delays (at worst) - and most of the time, both services and end-users will experience a much faster, smoother Internet.

      Of course, you'll never get AT&T to admit that the reason they can't do any better is that they're not only greedy but also technologically incompetent. Nonetheless, that is the reality of the situation. It is also something missing from said "study".

    Researchers at AT&T were very concerned that bandwidth would be further commoditized if the government does not act to prevent it. If At&t is required to treat everyone the same, then the consumer is free to choose the services that they want based on something called "quality of service" rather than a more practical method of choosing.... say... oh I don't know... uhm... a method of choosing based on how profitable it is for At&t. Having the consumer choose services based on what benefits At&t is a much more practical and convenient way for the consumer to purchase services over the Internet.

    At&t is very concerned about the bewildering number of options that the American consumer has available, and with the best interest of our customers at heart, At&t should assist the consumer by limiting the number of choices immediately.

    Spokesmen for At&t quickly said that "We do not want to the consumer to get the full unfettered benefit of the Internet because then we would have to actually add infrastructure to meet demand.

      Um...yah. I do. Your example is not tiering, but rather simply paying for bandwidth.

      Tiering would allow your ISP to define their traffic shaping, so that maybe Vonage VoIP packets get dropped while AT&T's VoIP packets get through because AT&T owns the network. Or they decide that newsgroups are unimportant and so now they take forever to access. Or maybe your neighbor fires up his TV-over-IP and all the sudden your dropped packet rate s
      • No, what you are describing is content based tiering (which is evil). I meant tiering, just on the consumer side. For instance, I would love to have a guaranteed connection of X, with an up to Y ( Y > X ) connection speed when bandwidth was available, assuming it was cheaper than just Y bandwidth. That is, have a tier 1 connection of X, and a tier 2 connection of Y-X. As long I can use my VOIP and some small webbrowsing on the side.

Enlighten us as to why this is now a problem considering the major Telecom bust that occurred a few years back was due to the overcapacity you had built into your networks? Google is going around buying up dark fiber from you guys while you're complaining about lack of infrastructure? Nonsense.

    It should be obvious that if you don't prioritize traffic based on QoS requirements that you will need more bandwidth. This has been a basic given for many years now. The question is what will it cost to prioritize the traffic to meet a given QoS level vs. just adding bandwidth.

    There are a lot lot of people who think the various prioritization schemes that have been proposed just won't work because they are not scalable - while a fast dumb core is.

    To me the problem with prioritization is that it is just harder to implement, and once it is in place it makes management harder. Also it tends to place limits as to what you can do on the IP network. Fast-dumb doesn't have these problems.

    What this research really proves is that a neutral network needs only double the bandwidth to replace a tiered one . Doubling the bandwidth is a lot cheaper, faster rollout, and more manageable than a tiered network. And it's more scalable than a complex tiered network. Plus, it has twice the bandwidth. And it doesn't have the flexibility and openness of a neutral network.

    Twice the bandwidth is an amazingly small multiplier. Its the sort of growth factor that one can reasonably imagine being accomodated with improvements in technology and build-out over a short period. So one has to ask what was the motivation for coming up with that number.

    Seems to me what they are thinking is that all the managed stuff will fit within existing capacity and then the unmanaged stuff requires new capacity. Or, to put it another way, all the available capacity needs to be managed.

    So the real statement here is "we need to close down the internet as it exists today so we can repurpose the network in order to generate greater revenues".

    What the big ISPs want isn't just a two-tiered Internet where some traffic gets priority over another. They want two distinct Internets. One were you have control and another where they have control. They'll probably share the same tier-1 backbones but everything below that will be separated (imagine a router configured to send packets from their sources directly to you via a hyper-speed backbone whereas all other traffic gets routed through a dozen or so more hops on the "economy" backbone).

    If you want a practical example of precisely how they they plan to violate network neutrality look at the DOCSIS 3.0 spec. It reserves about 80% of the bandwidth on the coaxial cable for video and telephone services that are exclusively provided by the cable company (i.e. no one else is allowed on). The other 20% of the bandwidth is provided as general Internet access (with the usual limited upload speed). This way they can be the gatekeeper for high-bandwidth content (i.e. video) and low-latency applications (i.e. VoIP) while every other business that wants access to their customers has to either pay to get on their high-speed channels or get stuck with the slow lane.

    The telephone companies are already rolling out technologies that divide up fiber connections in a similar fashion. The "big plan" is to get paid extra for that exclusive, high-speed and low-latency channel into people's homes. It is a hugely anti-competitive situation.

    If you provide streaming video to anyone on the Internet you will not be able to compete with the speed and quality of the video coming over Comcast's, AT&T's, and Verizon's dedicated pipes. If you're a VoIP provider that provides telephone service to anyone on the Internet you will not be able to compete with the low-latency and high quality of the big ISP's dedicated pipes. If you provide *any* service over the Internet all it will take for you to be crushed out of existence is for the big ISPs to start offering the same service on their dedicated, exclusive channels.

    It isn't about prioritizing traffic. It is about dividing it up and destroying the free market that is Internet access in people's homes. It is literally "divide and conquer".
