-## Different ways of understanding the layers of the internet 
-Network engineers talk about layers ​of networks. This can get complicated fast, but when thinking about regulation, you can think of three basic layers. ​+# The Dawn of the Internet: A Declaration ​of the Independence of Cyberspace
-{{ youtube>​mqhXMmQOOXU?small}}+In 1996, John Perry Barlow released a famous provocation about the limits of state power in regulating the internet. The Declaration,​ which we encourage you to **[read](https://​projects.eff.org/​~barlow/​Declaration-Final.html)** or **[watch](https://​www.youtube.com/watch?v=3WS9DhSIWR0)** in full, begins:
-The first is the '​infrastructure'​ layer (network cablesrouters, and protocols). This layer of the Internet is designed around the principle ​of a '​neutral'​ network (['​end-to-end'​ principle](https://​en.wikipedia.org/​wiki/​End-to-end_principle)):​ the responsibility for determining the content ​of communications rests with smart servers and users at the ends of the network, and the intermediaries ​are just responsible for passing messages along the chainAs the content passes over their networks, intermediaries ​are expected not to examine or intefere with it in any substantive way.+>​Governments of the Industrial Worldyou weary giants ​of flesh and steel, I come from Cyberspace, ​the new home of MindOn behalf ​of the future, I ask you of the past to leave us alone. You are not welcome among usYou have no sovereignty where we gather. 
 +>... I declare ​the global social space we are building ​to be naturally independent of the tyrannies you seek to impose on us. You have no moral right to rule us nor do you possess ​any methods of enforcement we have true reason to fear.
-This design principle is largely responsible for enabling the innovation that we see todayBecause the network itself is openthere is a real separation between ​the infrastructure (the pipes) and content (the data that flows over those pipes)This means that anyone ​is free to '​plug-in'​ to the internet and start providing services over the IP protocol and the hardware ​that connects all users together. This freedom at the infrastructure level allows lots of innovation at the endswhere providers can design new systems that can operate on top of standardised protocols.+Barlow'​s Declaration has played an pivotal role in shaping how we think about online regulationIn this extracthe makes two main claims about online regulation, which we will examine in more detail below. The first is that the internet is inherently unregulable by territorial governmentsThe second ​is that state regulation ​of the internet is illegitimateor governments should defer to the self-rule ​of cyberspace.
-The second layer can be thought of as the 'code' layerthis is the software that operates at the ends of the network to interact with users. ​The webserver that sends users the webpages they requested, customised and tailored for that particular user, is a software program running on a server or farm of servers. The apps that connect people to others, that allow users to chat, like, and swipe content created by others, are pieces of software running on mobile devices and personal computers that communicate with software running on the servers somewhere in 'the cloud'​. These programs -- their design, the input they accept, the algorithms they use to respond to requests -- are responsible for determining who we can communicate with and how.+##Barlow's First Claim: The Internet ​is Unregulable
-Finally, we can think of the '​content'​ layerthis is the material that is transmitted over the network infrastructure,​ selected and presented by codeThis is what we mostly mean when we think of the internet - the visible components of the network, the information that users express and receive. This is the layer at which most of the regulatory concerns arise; governments and private actors often have reasons to want to limit the flow of certain information+**Overview by Nic Suzor:​[Governing ​the Internet](https://www.youtube.com/​watch?​v=ybNGDquKVTc)**
-The history of internet regulation is most visibly a history of attempts by various parties ​to regulate content: offensive communications and pornogrpahy;​ private and confidential information;​ defamatory statements; and copyright content. Increasingly,​ however, attempts to regulate content involve struggles at the code and infrastructure layers, as pressure mounts on those who provide network infrastrucutre or services to build certain rules into their systems. The big struggles over internet governance now are largely a series ​of struggles over who gets to decide how networks are structured and how code operates.+>"​You have no moral right to rule us nor do you possess any methods ​of enforcement we have true reason ​to fear."
-## Infrastructure (The internet is a series ​of tubes)+Barlow'​s first claim that territorial states do not have the power to regulate the internet is largely descriptive. This claim is based on number ​of factors, including the decentralised nature of the internet, which is a network of networks that spans the globe without any real concern for jurisdictional boundaries. The internet enables billions of people to communicate largely anonymously across the globe, and the sheer quantity of content that is transmitted over the network each day is almost incomprehensibly large. All of these factors mean that, for the most part, any explicit interventions by governments can be trivially circumvented. If a website is shut down in one jurisdiction,​ it can be back up the next day somewhere else in the world. If a document is removed from one site, it will often quickly be reposted on a dozen more (see, for example, the '​[streisand effect](https://​en.wikipedia.org/​wiki/​Streisand_effect)'​)
-{{ youtube>​kwLTm1kJh3w?​small}}+However, it turns out that regulating the internet isn't quite impossible, just often very difficult. Fundamentally,​ the internet is not a separate place because the people who use it are real people, in real locations, subject to the very real power of their jurisdictions. The pipes that people use to communicate are cables and wireless links which also have physical presence. Where a Government can target the speakers, recipients or intermediaries involved in a communication,​ it can have a real effect on what information is transmitted via the internet. Figure 1 below, for example, illustrates the network traffic in Egypt over the period of the January 2011 revolution. You can clearly see the point at which the Egyptian Government had shut down the five major Egyptian internet service providers. The Egyptian Government'​s intervention epitomises the idea that _those who controls the pipes, controls the universe._ ​
-The resilience ​of the internet is often framed in John Gilmore'​s famous words:​((Philip Elmer-Dewitt‘First Nation in Cyberspace’ (1994) 49 TIME International http://​www.chemie.fu-berlin.de/​outerspace/​internet-article.html.))+The challenge ​of regulating ​the internet is finding an effective way to either identify and regulate the potentially anonymous creators of informationthe billions of potential recipients, or finding a way to regulate the networks along the chain of communication
->"​The Net interprets censorship as damage ​and routes around it." ​+**Figure 1: Who Controls the Pipes, Controls the Universe - Traffic to and from Egypt on 27-28 January 2011, from Arbor Networks**
-To understand this claim, we have to understand some principles about how the internet worksThe Internet is often defined as a '​network of networks'​Wikipedia has [a good definition](https://en.wikipedia.org/wiki/Internet):+![Graph of traffic ​to and from Egypt on January 27-28 2011, from Arbor Networks - Who Controls ​the Pipes, Controls the Universe](http://​www.wired.com/​images_blogs/​threatlevel/​2011/​01/​arbor_egypt-660x359.jpg)

->The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. ​+###A Case Study: Newzbin
-The Internet as we know it is built on [technologies funded ​by the US Department of Defence](https://en.wikipedia.org/wiki/DARPA), large public investments in infrastructure by academic and other institutions,​ and, from the 1990s, massive private investments in the deployment of new commercial and private connections around the world. ​+**[Overview of Newzbin ​by Nic Suzor](https://www.youtube.com/watch?​v=z8Ph8eO26q4)**
-From its very beginnings, ​the internet ​was designed to be _resilient_One of its key features ​is that it relies on an inter-connected web of computers to route information ​from any point to any other point on the internetIt is designed ​to be resilient ​to control or failure on any of these hardware linksIf there are problems with one part of the networkit can adapt automatically to route around broken links+While the internet ​is not unregulable,​ there are unique challenges facing regulatorsThe case of Newzbin, which was a popular Usenet indexing site, is one example ​from the fight against copyright infringementDubbed 'the Google of usenet'​ by the Motion Picture Association of America (MPAA), copyright owner groups sought ​to shut down the service that allowed others ​to easily find copyright films and other worksIn a 2010 Decision, ​the High Court in the United Kingdom (UK) found Newzbin liable for copyright infringementand the company was wound up and their website shut down.(([Twentieth Century Fox Film Corporation v Newzbin Limited [2010] EWHC 608 (Ch)](http://​www.bailii.org/​ew/​cases/​EWHC/​Ch/​2010/​608.html)))
-Sofor example, when a user in Australia requests a webpage ​from Facebook.com, a typical message might start here on a home computer, be transmitted along iiNet or Telstra'​s network a few times before hitting a major backbone or undersea cable, and then be passed along the chain by several other networked routers before finally reaching its destination at a webserver ​in the USThis could take anywhere from 10 to 20 different '​hops'​ along that chain and maybe 200ms on a fast linkFacebook'​s webserver in the US will receive ​that request, and send back the content ​to the user along a similar ​(but not necessarily the samepath.+Two weeks laterNewzbin2 rose from the ashesSomeone had copied the entire codebase of the old site and brought it back online ​on a server ​in the Seychelles, an archipelago of islands outside of UK jurisdictionThe MPAA went back to court, this time seeking an injunction ​that would require UK-based ISPs to block access to the websiteThe Court granted this order, marking an expansion of laws that were originally designed ​to block websites that hosted child sexual abuse material: [Twentieth Century Fox Film Corporation v British Telecommunications PLC](http://​www.bailii.org/​ew/​cases/​EWHC/​Ch/​2011/​1981.html) [2011] EWHC 1981 (Ch).
-So one of the reasons the internet ​is so hard to regulate is that messages can take any path between ​the two end points that worksIn factindividual messages are broken down into much smaller ​'packets', ​and the '​Internet Protocol' ​(IPprovides ​the standard for communication that enables all connected systems ​to talk to each other and pass data along the chain if requiredIf any link in this chain is broken, the Internet Protocol allows computers on the Internet to find other routes ​to get the message to its destination. This is where we get to Gilmore'​s quote: if a particular path is blocked or censoredit is often possible to pass a message along different paths to its destination+The system for blocking websites ​is not wholly effective. It turned out to be easy to bypass if users encrypted their connections or used a virtual private network to avoid the blockShortly after the injunctionNewzbin2 released a user-friendly application to 'utterly defeat' ​the filter[explaining that its app](http://​torrentfreak.com/​newzbin2-release-encrypted-client-to-defeat-website-blocking-110914/​could "break any updated web censorship methods or anti-freedom countermeasures"​. Ultimately, however, Newzbin2 closed down in 2012. It had lost the trust of its users, who were not sufficiently willing ​to pay to support ​the new serviceImportantlycopyright owners had also started to target ​the payment intermediaries that channeled funds to the organisation - intermediaries like MastercardVisa, Paypal, and smaller payment processors that use these networks
-<WRAP right third round box> +The Newzbin case study illustrates how regulating online content and behaviour can be an extremely difficult task. By cutting off the flow of money, the rightsholder groups were eventually successful in shutting down Newzbin. However, this took a lot of time and effort, and there is a good chance that many users of the service simply moved to newer, better hidden infringement networks. Overall, the copyright industry has had some succes in tackling large copyright infringers, but this is an ongoing arms race, as infringers continue to find ways around the regulations. ​

-* Some networks are more easy to regulate than others. When networks are organised as 'client/​server'​ networks, targeting ​the server can be very effective. When they are more decentralised,​ as in '​peer-to-peer'​ (P2P) networks, this becomes much more difficult.+##Barlow's Second Claim: State Regulation of the Internet is Illegitimate
 +**Overview by Nic Suzor[The Legitimacy of Online Regulation](https://​www.youtube.com/​watch?​v=A0m_GZC4x2w)**
-<WRAP round box> +The second claim that Barlow makes in his Declaration is that state governments _should_ defer to cyberspace self-ruleor what we call '​private ordering'​. Barlow explains ​that:
-Tom Armstrong and Mitch Hughes each explain how this works in relation ​to Australians accessing Netflixbypassing industry agreements ​that require geographic market segmentation of content:+
-{{youtube>​prhQKAJG8nA?​small}} {{youtube>​rk0aeKMCRFs?​small}} +>"We believe that from ethics, enlightened self-interest,​ and the commonweal, our governance will emerge."​
-One way of avoiding regulation online ​is through ​the use of a Virtual Private Network (VPN)A VPN can create an encrypted '​tunnel'​ from an entry point in one jurisdiction, to an exit point in another. By using a VPN, a user can appear ​to be located ​in another ​jurisdiction. This means the user can avoid any jurisdiction-based filtering or blocking, and also make it much more difficult ​to track down his or her real location ​and other identifying information.+Barlow'​s argument ​is that the rules and social norms created by online communities to govern themselves will be better than anything imposed by territorial states. This was expressed by Johnson and Post in a famous 1995 article as a general principle that there is “no geographically localized set of constituents with strong and more legitimate claim to regulate [online activities]” than the members of the communities themselves.((David Johnson and David Post, ‘Law and Borders--The Rise of Law in Cyberspace’ (1995) 48 Stanford Law Review 13671375)) In addition ​to arguing that online communities should be able to govern for themselvesBarlow and Johnson and Post asserted that if territorial governments try to impose their own laws on borderless internet, users will never be able to work out what set of rules they are subject to. The consequence of governments attempting to prevent online communities from regulating themselves, according to Post, would be:((Post, '​Governing Cyberspace: Law' (2008) http://​www.academia.edu/​2720975/​Governing_Cyberspace_Law))  
 +> “... the chaotic nonsense of Jurisdictional Whack-a-Mole"​. 
 +As we will see in the [[jurisdiction|Jurisdiction chapter]], ​the legitimacy of any one nation claiming ​jurisdiction ​over transnational communications is still a vexed issue. As the Australian High Court noted in the _Dow Jones v Gutnick_((_Dow Jones and Company Inc v Gutnick_ [2002] HCA 56 http://​www.austlii.edu.au/​cgi-bin/​sinodisp/​au/​cases/​cth/​HCA/​2002/​56.html?​stem=0&​synonyms=0&​query=title(dow%20jones%20and%20gutnick%20)&​nocontext=1)) case, nation states purport to have a responsibility to protect their citizens'​ interests online, and certainly a desire ​to regulate online content ​and behaviour
