Neutral Net Needs Twice the Bandwidth of Tiered

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."

And sometimes it is worth pursuing an outcome that is not maximally effecient for other reasons, a fact that people seem to overlook sometimes. So what if the internet is half as fast as it could be; that is an acceptable trade-off for a free and open internet.

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.

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!"

Tier it off and you'll make it about as useful as the television networks.

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.

Show me the bandwidth

[Anonymous Coward]

But we're already paying eight times the cost of neutral net bandwidth, so in what way is this study relevant to the consumer?

Re:Show me the bandwidth

[enrevanche]

It is relevant in that this study can be used by the congressman that have been paid for by AT&T to oppose net neutrality.

It is relevant because it will allow AT&T to make a system for which they can charge vastly more than they do now.

It is relevant because it will allow AT&T to reduce your choice more and more over time and to take bigger and bigger pieces of the internet pie.

It is relevant because it will allow AT&T to force more and more companies to deal directly with them for connectivity if their customers want any access to the AT&Ts customers (or shall we call them victims.)

Wait a second...

[vigmeister]

When I am looking at leasing an internet connection at home, I equate bandwidth with speed and this is a reasonably rational assumption (today).

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!

The new way to spin "net neutrality is bad"

[grev]

Majority of people don't know what net neutrality is, they don't care, and they never will. Now, whenever the issue is brought up in the mainstream news or whatever, big business can talk about how it's half as efficient, in addition to being communist and un-American. I can only imagine how this will turn out.

Bandwidth

[Renraku]

Bandwidth is a funny resource.

Imagine if you had a tree that bore fruit once or twice a day. But if you did not eat the fruit within an hour, it spoiled. There's no point in trying to conserve the fruit unless your demand is higher than the output of the tree.

Its always good to have say, 10% free. Out of ten fruit, leave one so that any surprise visitors might have a quick snack as well.

Of course, the other reason you might try to conserve it is to create artificial demand. Now, half of your crop goes to waste. You sell the other half for very high prices saying that your supply just can't keep up with demand and that you must sell them at a higher price due to the whole free market thing.

Point is, every fruit you don't sell will be useless in an hour. But its better to let a fruit rot than to sell it for a decent price, after all.

What Happened to All the Overcapacity?

[rbegga]

To the Bandwidth Providers:

We keep hearing these arguments from the Telco's and Cable COs about how much more difficult it will be to build and maintain an open Internet because of the bandwidth requirements that imposes. 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. I don't believe you guys can't figure out a model to make this work for you and us without getting the government involved.
