Neutral Net Needs Twice the Bandwidth of Tiered 271
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."

Analyzing the situation and pluggin in numbers,
Assume that the bandwidth available is fixed. What they're essentially saying is that either all of us can get 50BjBps (Bajillion Bps) regardless of the importance of our packets, or using a pareto distribution, 20% of us will get 80BjBps and 80% will get 20BjBps effectively?
I know these are rough numbers, But damn if I know which one I'd prefer... I think at the end of the day, a clearly defined set of standards for prioritization needs to first be developed by an independent body (ICANN/ISO/IEEE?). Once that is done, we can debate net neutrality. Right now, none of us actually know what is going to be prioritized. If streaming video for doctors performing live surgery is prioritized, I'm OK with that. If companies can buy priority for commercial, then I am kind of opposed to it unless I am guaranteed that these priority purchases will subsidize my connection.
Maybe they can have two levels of internet access: Neutral internet access (~$50 p.m) and Tiered access (~$10 p.m). Then let these levels fight it out. Of course, the implementation is unclear to me as I am not network engineer. To think about it, isn't this tiered in itself?
Cheers!

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.

To look at it another way. A provider desiring to guarantee QOS... latency, jitter and minimum bandwidth for services such as VoIP, without having the benifit of having control over that bandwidth, would need to have a lot more bandwidth to meet those expectations.
This is just restating the idea that QOS enforcement becomes irrelevant with enough bandwidth.

Heh, heh. I can remember when the phone companies wouldn't allow modems because (it seemed to those of us who used them, anyway) it allowed you to do things that the phone company hadn't thought of. "Sending bits across voice lines? NO! You'll have an expensive leased line installed if you want to do that. And you'll lease equipment from us, too. Or we'll cut off your service!"
You've hit the nail on the head. That's the model the phone companies are trying to emulate. It explains their ridiculous subscriber plans that include "Content by whoever".
I'm not at all surprised at the difficulty that the phone companies are having with the Internet. They had to be dragged -- kicking and screaming -- into accepting packet switched networks in the first place. My guess is that an entire generation of managers (or two) at these companies need to retire before we'll see anything like a basic understanding of the Internet in these companies' actions.

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.

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.

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.

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".

A net neutral network provides a level playing field on which content providers can enter without barriers and compete against anybody.
A non-neutral net does not provide the ability of content vendors to enter the market on an equal basis without setting up a special deal with a network bandwidth provider. In practice, this means content is bundled with service, and that the network providers provide a poor selection of content.
If you want to see what a non-neutral net looks like, look know further than cell phone companies, who have all lame proprietary multimedia and information services.
