See A monkey hanger’s guide to Net Neutrality:

During the Napoleonic Wars, 1805, legend has it that citizens of Hartlepool tried and hung a monkey … believing it to be a French spy.

Last year, the US Congress almost “hung the monkey”, too.

The piece is both entertaining and informative. Britain’s take on net neutrality: “an answer to problems we don’t have, using a philosophy we don’t share”

The first major debate on net neutrality before members of the British Parliament was held today, and more or less elicited yawns all around:

The first significant Net Neutrality debate to take place in the UK was held today at Westminster. Chaired by former trade minister Alun Michael and the Conservative shadow trade minister Charles Hendry, the event attracted the chief Telecoms regulator and ministry policy chief, a clutch of industry representatives, and a sprinkling of members of both houses.

What emerged from the sessions is that ‘Neutrality’ is one of those incomprehensible American phenomenons, from which we’ve mercifully escaped. Your reporter was one of those invited to give a briefing – having reported on the issue from both sides of the pond – and said as much. But in the expectation that this would be the heretic view, rather than the near unanimous consensus opinion.

Summing up, Michael described the clamour for pre-emptive technical legislation as “extreme… unattractive and impractical”.

It was, he said, “an answer to problems we don’t have, using a philosophy we don’t share”.

That wasn’t the only surprise.

Google was invited to appear on the panel, but declined on account of fears that it wasn’t neutral enough. That’s sad, but probably indicative of the on-line giant’s change of heart on the subject of a smarter Internet.

This is some very encouraging news:

Technology Review, which jumps on the Web 3.0 bandwagon in its current issue, reports that Stanford’s Clean Slate Design for the Internet program will be holding a coming out party this Wednesday. The interdisciplinary program seems to take the end of “net neutrality” as a given. Its thrust, in fact, is to make the Internet less Internety (at least as we’ve come to define the term) by redesigning it to be “inherently secure,” by making it possible to “determine the value of a packet … to better allocate the resources of the network, providing high-value traffic with higher bandwidth, more reliability, or lower latency paths,” and by “support[ing] anonymity where prudent, and accountability where necessary.”

The current Internet is chock-full of the vestiges of its heritage as an academic research network, lacking mechanisms for security and authentication and practically inviting abuse. A new Internet, redesigned from the ground up with a realistic assessment of use and abuse, has been needed for fifteen years, so this effort is long overdue. Internet2 could have done this, but didn’t have the technical firepower needed to take public networking to the next level.

Who does? Well, lots of people:

A growing number of researchers are acknowledging that the Internet is fundamentally flawed and needs an overhaul. The Stanford program is just one of a number of initiatives to fix the Internet. (See “The Internet Is Broken.”)

Bob Metcalfe, inventor of Ethernet and founder of 3Com, believes that there needs to be a way to ensure dedicated bandwidth. “The Internet was designed to get teletype characters echoed across the U.S. in under a half second,” Metcalfe wrote in an e-mail interview. “Soon we’ll have to handle [high-definition] video conversations around the world. The Internet must now allow bandwidth reservation, not just priority, to carry realtime, high-bandwidth communication–video in its many forms including video telephone.”

Metcalfe thinks the Clean Slate project is a great idea but believes that significant challenges lie ahead. “When you’re dealing with infrastructure, in reality, off the Stanford campus … nobody gets a clean slate,” Metcalfe says. “After the brainstorming, the project will have to work on migrations, transitions, compromises, and clever hacks to get the Internet moving gradually toward their ideals.”

And that, my friends, is why I’m against Network Neutrality: I’m an inventor of network protocols (twisted pair Ethernet, wireless LANs and PANs) and my job is find bottlenecks and eliminate them. Needless regulation falls into that category.

This is the kind of work that David D. Clark does (Clark was the principal author of the “End-to-End Arguments in System Design” paper cited by pro-neuts as gospel), and he’s no more sanguine than I am about the Internet’s fragility:

At the same time, the Internet’s shortcomings have resulted in plunging security and a decreased ability to accommodate new technologies. “We are at an inflection point, a revolution point,” Clark now argues. And he delivers a strikingly pessimistic assessment of where the Internet will end up without dramatic intervention. “We might just be at the point where the utility of the Internet stalls — and perhaps turns downward.”

Indeed, for the average user, the Internet these days all too often resembles New York’s Times Square in the 1980s. It was exciting and vibrant, but you made sure to keep your head down, lest you be offered drugs, robbed, or harangued by the insane. Times Square has been cleaned up, but the Internet keeps getting worse, both at the user’s level, and — in the view of Clark and others — deep within its architecture.

Over the years, as Internet applications proliferated — wireless devices, peer-to-peer file-sharing, telephony — companies and network engineers came up with ingenious and expedient patches, plugs, and workarounds. The result is that the originally simple communications technology has become a complex and convoluted affair. For all of the Internet’s wonders, it is also difficult to manage and more fragile with each passing day.

Network neutrality isn’t just a distraction, it’s a positive danger.

I’ve written dozens of posts on net neutrality since the debate started in the American media last spring, and yet another dozen on Internet regulation before the public debate started. Most of my recent writing has been reacting to press reports, political events, and other people’s blog posts, and it’s fairly hard to follow, I expect, to those who haven’t been reading all along. So I decided to to collect the relevant considerations into a single post.

Main points:

• Everything we know about regulating networks we learned from telephony.
• The Internet is radically different from the telephone network, hence traditional regulatory models don’t fit.
• The Internet is in its infancy and more experimentation is needed.
• Any regulation that’s not guided by empirical evidence of specific harm (not simply speculative, “what if?” scenarios) is likely to be wrong.
• The technical challenges to keeping the Internet running are so great that we don’t have the luxury of adding reams of unnecessary regulations to it.
• The appropriate regulatory stance is to watch for marketplace harm and be prepared to react to it.

These are some of my better posts on the subject:

How Much Bandwidth is Enough?

Toward an Accountable Internet.

And the complete archive is here.

I work in the network systems business, for a company that competes with Cisco. I like to point out the failings of the companies my company competes with, and I also like to highlight the instances where they get it right. Cisco has lately been in the getting it right camp, and here are a couple of examples.

The public policy lead, Bob Pepper, has written one of the better pieces on net neutrality:

The supporters of net neutrality regulation believe that more rules are necessary. In their view, without greater regulation, service providers might parcel out bandwidth or services, creating a bifurcated world in which the wealthy enjoy first-class Internet access, while everyone else is left with slow connections and degraded content.

That scenario, however, is a false paradigm. Such an all-or-nothing world doesn’t exist today, nor will it exist in the future. Without additional regulation, service providers are likely to continue doing what they are doing. They will continue to offer a variety of broadband service plans at a variety of price points to suit every type of consumer.

Depending on their requirements and preferences, some consumers will choose to pay more for premium service. Others will decide that they don’t need such high service levels, so they will pay less. Inevitably, the market will adjust, just as it has in the past, to this varied population and its preference for a highly diverse mix of services, quality, bandwidth and price. This is the hallmark of a competitive market.

This is so good, it was banned from Wikipedia.

And on the business side, this makes a heck of a lot of sense:

Cisco Systems (CSCO) on Thursday announced plans to acquire online conferencing service WebEx (WEBX) for $3.2 billion in cash.

WebEx’s subscription service allows customers to share presentations and host video conferences online. Cisco will pay $57 for each WebEx share. The deal is worth about $2.9 billion, after WebEx’s cash reserves are subtracted.

The deal has been approved by the boards of both companies but still must get the OK from regulators. It is expected to close in early summer.

Contrary to some uninformed commentary, WebEx is not a “Web 2.0 company,” it’s a high Quality of Service Internet bypass for small and medium size companies who want on-demand QoS for occasional use. I’ve worked for several companies who use the WebEx service, and find that it does exactly that it’s claimed to do, and does it well. Cisco can expand the market for its routers by increasing the size of the WebEx business, and generally move more data to IP networks, and that’s the key to success for them.

Some critics have charged Cisco’s Pepper with “not getting it”, the usual complaint that net neutrality fans make against others:

While I agree with him that more rules may not be necessary, I disagree with the framing of his argument. The Net is not just a service, users don’t just consume it, the market is hardly competitive, and many choices are overpriced or just not there.

First, the Net is a vast set of connections on which countless services can be deployed. Telephony and television are just two. Because telephone and cable companies offer Internet connections as a secondary “service” on top of their primary businesses, customers tend to think of the Net in the same terms — something extra you get from our phoen or cable company. This is wrong. In terms of what-runs-on-what, the Internet will in the long run become a base-level utility, and we will come to regard telephony and television as two among many categories of data supported by that utility, just as we now regard Fedex delivery as a service that runs on roads, but does not control them.

The error here is failing to realize that all communications services aren’t about the Internet, whatever its many virtues may be. Cell phones are not about the Internet, cable TV is not about the Internet, and private corporate networks are not about the Internet. And it’s certainly no more fallacious to talk about the first-hop Internet subscriber service as a service than it is to talk about it as “the Internet.” The Internet is a system that interconnects private IP networks, not the system that connects the Searls household to a default Internet gateway, nor is it the be-all and end-all of communication.

It would be nice, I suppose, if the day came where live telephone and television services were to migrate to the Internet, but that would hardly signal a significant advance in human civilization: television will still suck, and the Internet will remain far behind the cellular telephone network in terms of convenience and mobility.

So the score this week is Cisco 2, Utopians 0.

Jay Sulzberger is a loopy open-source advocate from New York and essentially a Marxist. His contribution about net neutrality to the FTC is about the funniest attempt at advocacy I’ve ever read. Here’s a little:

Now cable TV is not the Internet, but most speakers at the FTC’s workshop spoke of the Net in ways that treated it as if it were just a form of interactive TV, with some extra special services bundled with interactive TV, “web viewing”, email, and doubtfully, voice over IP.

Questions around building another, perhaps several other, cable TV networks, are not part of the issue of Network Neutrality, because the Net is not TV of any kind.

Use of the word “broadband” to mean both the Net and cable TV helps perpetuate the fundamental confusion.

He goes on to throw a lot of dirt at a “duopoly” and tout the wonders of the Quote of the Day port. How this guy manages to feed himself on a regular basis is a complete mystery to me, but David Weinberger calls his rant “lucid.” Clearly, that’s a relative term.

Sulzberger is confused about the scope of net neutrality in particular and broadband regulation generally. When AT&T said Google wasn’t going to be allowed to use its pipes for free, the issue under discussion was IPTV, a broadband service that is perhaps easily confused with Internet subscriber service, but not actually identical. IPTV runs alongside voice and Internet subscriber services on residential broadband networks, but not through the Internet service. AT&T couldn’t care less about messing with QOTD, but they’re very serious about making money from IPTV.

Misguided and nonsensical ravings of this type aren’t really helping anybody, but they’re never going to stop. The Jay Sulzbergers and David Weinbergers of this world need to believe that an evil conspiracy is out to shut down QOTD, and no amount of rational argument will persuade them otherwise.

The new net neutrality paper from Florida U. is absolutely hilarious:

Whether to legislate to maintain “net neutrality”, the current status quo of prohibiting broadband service providers from charging online websites for preferential access to their residential and commercial customers, has become a subject under fierce debate. We develop a stylized game-theoretic model to address two critical issues of the net neutrality: (1) who are gainers and losers of abandoning net neutrality, and (2) will broadband service providers have greater incentive to expand their capacity without net neutrality.

We find that if the principle of net neutrality is abandoned, the broadband service provider definitely stands to gain from the arrangement, as a result of extracting the preferential access fees from the content providers. The content providers are thus left worse off, mirroring the stances of the two sides in the debate. Depending on parameter values in our framework, consumer surplus either does not change or is higher, and in the latter case, while a majority of consumers are better off, a minority of them is left worse off with larger wait times to access their preferred content. The social welfare increases when compared to the baseline case under net neutrality when one content provider pays for preferential treatment, but remains unchanged when both content providers pay. We also find that the incentive for the broadband service provider to expand under net neutrality is unambiguously higher than under the no net neutrality regime. This goes against the assertion of the broadband service providers that under net neutrality, they have limited incentive to expand.

Aside from their use of pidgin English (“the current status quo of prohibiting…from charging”, “critical issues of the net neutrality,” “has become a subject under fierce debate,” “a majority are better off, a minority is worse off”) the authors embarrass themselves with a wholly nonsensical definition of the terms of the debate. As Scott Cleland points out, if net neutrality really were the status quo, legislation would not be needed simply to preserve it.

In fact, net neutrality legislation seeks to create a new status quo where light users of Internet subscription services are required to subsidize heavy users, and where telecommunications companies would be prohibited from offering non-Internet-based IPTV services unless competitors could access their private IPTV facilities for free (where “free” means for no additional charge beyond what they pay for Internet service today.)

Verizon and AT&T offer IPTV services today, so this is clearly not a question of preserving the status quo.

The professors jump through hoops in order to “prove” that light users should be required to subsidize heavy users, and then baldly assert that the only difference between 10 Megabit Ethernet on fiber (10Base-FL [sic]) and Gigabit Ethernet is at the transceiver level. No dudes, not even close: system interfaces, buses, and MAC controllers have to be re-engineered to run faster, and distances suffer.
