Could Edge-Caching Violate Net Neutrality?

December 18th, 2008  |  by bballou  |  Published in Future of the Internet  |  4 Comments

Our little corner of the blogosphere has been lit on fire by the recent article in the Wall Street Journal claiming that Google was coming out against Net Neutrality. Now, there are plenty of problems with this article. Contra WSJ, to quote David Isenberg:

“Google’s edge caching isn’t new or evil
Lessig didn’t shift gears on NN
Microsoft and Yahoo have been off the NN bandwagon since 2006
The Obama team still supports NN
Amazon’s Kindle support is consistent with its NN support”

This is all more or less true (I think Lessig would himself agree that his opinions about net neutrality have evolved). However, none of this says that Google isn’t violating the principle of net neutrality. Let’s use Google’s own summary of the idea, that broadband providers “should not be allowed to prioritize traffic based on the source, ownership or destination of the content.” Strictly speaking, this does seem to conflict with Google’s OpenEdge program. The program aims to cache Google’s search and video content on servers within network operators’ facilities. Such deals would save bandwidth for the network operators and increase access speeds for broadband customers. Such deals would also give Google a distinct advantage over its search and video competitors. Says one of the commenters on David Isenberg’s above-referenced blog:

“The plan is for Google to install equipment that will bypass the public Internet and ensure that their content, e.g. YouTube, will be delivered to ISP customers faster and more reliably than competing services such as Netflix Instant Watch that depend on the public Internet for delivery. If there weren’t a performance advantage, there would be no reason to do this.

“Whether this violates [network neutrality] depends on whose definition you take, and from what era. Current Lessig says it’s fine as long as any (rich) company has access to the [cable operator], but historical Lessig said such arrangements (“access tiering”) are not fine because only a few large players can enjoy their benefits.”

Now, this might not be bad. It might not hurt innovation. It might not be evil. But it certainly violates net neutrality, if we define the principle strictly as bit-by-bit non-discrimination. That said, such a violation might not be such a big deal. Instead of asking whether this deal prioritizes certain services or content over other services or content, let’s ask whether this deal promotes users’ autonomy and generative capacity. Long-term, those seem to be the questions that matter.

Finally, at the risk of burying the lede, let me add that before publishing this post I asked JZ’s thoughts on the matter. Here’s what he wrote:

“I don’t see this as a gotcha moment, but it’s a useful pointer to a larger debate about the role of intermediaries like Akamai, which make high-bandwidth streaming work better for its customers thanks to similar arrangements.  Akamai and deals like the ones Google seek might be helpful to the Net because they ease the pressure for more formal, network-embedded discrimination, since big content providers can have their needs met with what amounts to an endpoint kludge.  And so long as the network itself isn’t discriminating, P2P provides a neat form of easy high-bandwidth distribution within the reach of any content provider — so long as the material in question is popular enough for enough P2P users to seed it.  But at its extreme, if one imagines a public Net with no further buildout and a migration of most content to edge staging points by those who can afford it, the rise of bandwidth arbitragers isn’t good.  I’m not currently that worried about this scenario because the bottlenecks in bandwidth turn out to be towards the edges rather than in the middle of the network.”

    Net neutrality in the sense of prohibiting anti-competitive behaviour is probably good for us all. This is appropriately enforced at law.

    Net neutrality in the sense of ensuring that all bits are created equal is an absurdity. I want an internet designed by engineers, not by lawyers and anthropologists.

    Plenty of people do edge caching. It’s a sensible development of the web architecture. It’s by no means exclusive to big companies, either: you can buy edge-service from Amazon as part of their cloud computing and storage offering. I don’t doubt that as cloud models take hold, we’ll see more and more such `kludges’ take hold, to borrow JZ’s term. Perhaps at that point some people will sit down and design the next generation of protocols which take account of this. We’ll probably end up with an internet with all sorts of internal services. Whether or not that is a good thing is an engineering matter only.

  • The Future of the Internet: Five Years Later
  • In 2008, The Future of the Internet called attention to a “sea change” in the way consumer devices interact with the Internet. “The future is not one of generative PCs attached to a generative network,” the book warns; “it is instead one of sterile appliances tethered to a network of control.” In response to the security threats posed by malicious third-party code, increasing numbers of users will likely gravitate towards gadgets “tethered” by continuous communication between product and vendor. And this proliferation of tethered computing—the “appliancization” of PCs—will deal a serious blow to the principles of generativity and free expression that drove the early Internet.

    Since the publication of The Future of the Internet, the ethos of strict appliancization has taken a new turn. In 2011, Professor Zittrain wrote an update on the book’s message: “at the time of the book’s drafting, the alternatives seemed stark: the “sterile” iPhone that ran only Apple’s software on the one hand, and the chaotic PC that ran anything ending in .exe on the other. The iPhone’s openness to outside code beginning in ’08 changed all that. It became what I call “contingently generative” — it runs outside code after approval (and then until it doesn’t).” This trend towards contingently generative models continues into the present day, and represents a shift similar in many respects to the one The Future of the Internet predicted.

    Jon Brodkin and Peter Bright’s Ars Technica op-ed on the Microsoft Metro app store offers some valuable commentary on a big development in this “sea change.” The article recognizes that “Microsoft is imitating Apple in one very bad way, by limiting the distribution of Metro applications to a Microsoft-controlled app store… by bringing Windows to tablets, Microsoft could strike a blow for openness in a market dominated by a closed system. Instead, Microsoft is bringing the same restrictions found on iPads to both Windows tablets and PCs.” As forecasted by The Future of the Internet, devices that only run approved code are gaining popularity. Metro, the curated user interface that has found its way onto Microsoft’s tablets and PCs (in the case of the PCs, alongside a fully-functional desktop mode capable of side-loading non-Windows Store applications), won’t run applications from outside the Windows Store. Moreover, the apps available through the Store are subject to a bevy of restrictions on content. With these restrictions on installable applications come the restrictions on generativity that The Future of the Internet anticipated: “lock down the device, and network censorship and control can be extraordinarily reinforced.” And, as the Ars Technica piece observes, the Windows Store’s rules would exclude critically-acclaimed content like the video game Elder Scrolls: Skyrim, simply for its PEGI 18/ESRB M rating. It isn’t hard to extrapolate, as Brodkin and Bright do, that these rules could give rise to debacles similar to Apple’s (repealed) ban of a satire app developed by a Pulitzer Prize winner.

    Though the Windows Store’s restrictions resemble Apple’s policies in many ways, there is a crucial difference: Metro-running Windows 8 products are designed as PC replacements, rather than sui generis devices like the iPad. And since Windows desktops have long been preferred gaming platforms, the theoretical exclusion of content like Skyrim from the Windows Store makes Windows 8’s emphasis on the Metro interface particularly jarring.

    With Metro, Microsoft has made a decisive move towards contingent generativity. Brodkin and Bright note that “there are security benefits to a closed app store model, particularly for less tech-savvy users who may not understand all the dangers on the Web. There are also, arguably, convenience benefits; end-users can be reasonably confident that the apps they download will work correctly and be at least marginally useful…But while these security and convenience benefits might be enough to justify the existence of a curated app store, they don’t justify the decision to make that store the only option for all users. Informed users should be allowed to install applications from wherever they want.” Brodkin and Bright prefer a system like Gatekeeper, a fixture in newer versions of Apple’s OS X, from Mountain Lion forward. Gatekeeper gives users the choice to restrict their operating system to App Store apps and outside apps that have been signed with Apple-issued Developer IDs, or open up the device to all programs, whether or not they’ve been vetted by Apple. The “Future of the Internet” Blog is fairly enthusiastic about Gatekeeper: about a year ago, a post here suggested that “the middle ground of allowing non-App Store signed code may represent the best of both worlds.” But we were quick to warn that Gatekeeper strikes a tenuous balance: “one small tweak — lose that Control-click for sideloading — and OS X could fully merge with iOS, both in functionality and in security methods.” Metro’s riff on content control could be just that sort of tweak—especially given recent speculation that Microsoft may dump desktop mode in Windows 9, leaving only Metro.

    Moreover, a contingently generative business model like the Windows Store’s carries some ethical implications that, while not damning, are certainly worth examining. Distribution systems like the Windows Store, Apple’s App Store, and the Android Market receive 30% of the sales revenue from applications sold in their stores (in the Windows Store, this cut drops to 20% after an app reaches $25,000 USD in revenue). Further restrictions on side-loading in new operating systems would drive a great deal of business towards big companies’ proprietary marketplaces—and with that traffic would come big payouts. With the uptick in store traffic that tighter gatekeeping would engender, it’s easy to imagine the equilibrium of Mac’s OS X Gatekeeper being forsaken for more restrictive, and more lucrative, operating systems. To analogize, a la The Future of the Internet: when the company that makes your computer requires you to install programs through their official store, it isn’t so different from the company that makes your toaster forcing you to buy from their bakery—and taking a cut out of every bread purchase you make.

    Even though Windows 8 PC users can still make use of a fully-functioning desktop operating system, Microsoft’s failure to include a side-loading option for the heavily-emphasized Metro interface—particularly in devices marketed as PC replacements—is a step in the wrong direction. It’s also an indication that the seas are changing in the way The Future of the Internet predicted. Given that Android’s more open approach to outside applications[1] still leaves the Android Market increasingly economically viable, Ars Technica is right to voice its disappointment in xenophobic operating systems like iOS and Metro.

    [1] Though the Google Play approach to openness is far from perfect! Ad-Blocking apps were recently pulled from the Play Store, in a move that will come to illustrate just how viable it is to distribute a side-loaded Android app without any help from the Play Store.

  • Rock star RA wanted
  • I’m seeking a full-time one-year rock star research associate to engage with a variety of projects and classes, with a broad opportunity to immerse in cyberlaw and Internet topics.   Blurb below, with more information on how to apply at <http://cyber.law.harvard.edu/getinvolved/jzra>.  …JZ

    –

    Professor Jonathan Zittrain of Harvard Law School, the Harvard Kennedy School of Government, the Harvard School of Engineering and Applied Sciences, and the Berkman Center for Internet & Society, seeks a full-time research associate in Cambridge, MA for a period of one year, beginning no sooner than June 1, 2013.

    This position requires the ability to absorb large amounts of written and other media materials from various sources (including but not restricted to: original sources, scholarly articles, news articles/blogs, interviews, databases) in a short amount of time, critically analyze that material and render it forward. This could take the form of prep materials for panels, conferences and presentations; article outlines; fact checking materials; original article or paper drafts; slide decks or other digested forms. The research assistant should be prepared to help prepare materials for class sessions and syllabi, lead discussions and work with project managers to accomplish research-related goals.

    Research is often self-directed with little outside guidance beyond broad outlines and themes (though occasional targeted research assignment for a specific fact or image can be expected, and feedback is provided), so the ability to quickly critically appraise sources and identify interesting, relevant and original paths is essential. Wide-ranging interests and the ability to work on almost any issue or topic that arises is a plus, as is an ability to ramp up quickly on unfamiliar fields or topic areas. Excellent writing and editorial skills with an attention to detail are also required.

    This job is an ideal opportunity for those interested in future graduate school or law school studies, whether currently admitted or still applying to such programs.

    Over the course of the year, a motivated individual will sharpen and focus his or her research agenda and make valuable contributions (in his or her own name) to the field of cyberlaw and beyond, while being exposed to interesting thinkers in academia, industry, and government. A research associate in this position will work very closely with Professor Jonathan Zittrain and his team, assisting in a variety of research areas, e.g. ubiquitous human computing, mesh networking, and cybersecurity, as well as on topics around access to knowledge and open scholarly publishing under the auspices of the Harvard Law School Library.

    The position will not start before June 1, 2013.  As with all Berkman staff positions, this is a term position, ending June 30, 2014.

  • F-T: Don’t sue over tweets
  • I just published a short piece in the F-T in the wake of legal threats against users who tweeted or retweeted a link to a BBC report of child abuse that turned out to be wrong.  Here’s the full text –

    Those who didn’t see the false child abuse accusations against Lord Alistair McAlpine on an ill-considered BBC documentary may have instead heard about them through social media. This week, London’s Metropolitan Police suggested they might file charges against those Twitter users who sullied the reputation of the retired Conservative politician by knowingly repeating the lie that he was a child abuser. But the police may be less fearsome to the average BBC-linking tweeter than Lord McAlpine himself. Read more »

    Meet Maya, a four-year-old child who could lose her ability to speak with the elimination of an app from the iOS App Store.

    As detailed in the Nieder family’s original blog post on the subject, Maya uses Speak for Yourself (SfY), an iPad app that serves as an “augmentative and alternative communication” (AAC) device. Before finding SfY, Maya had tried multiple AAC devices, but hadn’t found one that worked for her. Read more »
