How the Internet works

On the Internet, when you want to retrieve a document from another computer, you request a service from this computer. Your computer is the client, the computer on which the information you want to access is stored, is called the server. Therefore the Internet's architecture is called client-server architecture.

A common set of standards allows the exchange of data and commands independent from locations, time, and operating systems through the Internet. These standards are called communication protocols, or the Internet Protocol Suite, and are implemented in Internet software. Sometimes the Internet Protocol Suite is erroneously identified with TCP/IP (Transmission Control Protocol / Internet Protocol).

Any information to be transferred is broken down into pieces, so-called packets, and the Internet Protocol figures out how the data is supposed to get from A to B by passing through routers.

Each packet is "pushed" from router to router via gateways and might take a different route. It is not possible to determine in advance which ways these packets will take. At the receiving end the packets are checked and reassembled.

The technique of breaking down all messages and requests into packets has the advantage that a large data bundle (e.g. videos) sent by a single user cannot block a whole network, because the bandwidth needed is deployed on several packets sent on different routes. Detailed information about routing in the Internet can be obtained at http://www.scit.wlv.ac.uk/~jphb/comms/iproute.html.

One of the Internet's (and of the Matrix's) beginnings was the ARPANet, whose design was intended to withstand any disruption, as for example in military attacks. The ARPANet was able to route data around damaged areas, so that the disruption would not impede communication. This design, whith its origin in strategic and military considerations, remained unchanged for the Internet. Yet the design of the ARPANet's design cannot be completely applied to the Internet.

Routing around depends on the location of the interruption and on the availability of intersecting points between networks. If, for example, an E-mail message is sent from Brussels to Athens and in Germany a channel is down, it will not affect access very much, the message will be routed around this damage, as long as a major Internet exchange is not affected. However, if access depends on a single backbone connection to the Internet and this connection is cut off, there is no way to route around.

In most parts of the world the Internet is therefore vulnerable to disruption. "The idea of the Internet as a highly distributed, redundant global communications system is a myth. Virtually all communications between countries take place through a very small number of bottlenecks, and the available bandwidth isn't that great," says Douglas Barnes. These bottlenecks are the network connections to neighboring countries. Many countries rely on a one single connection to the Net, and in some places, such as the Suez Canal, there is a concentration of fiber-optic cables of critical importance.

History: European Tradition

Only in Roman times the first rights referring to artistic works appeared. Regulations resembling a lasting exclusive right to copy did not occur until the 17th century. Before copyright was a private arrangement between guilds able to reproduce copies in commercial quantities.

In France and Western European countries "droits d'auteur" or author's rights is the core of what in the Anglo-American tradition is called copyright. Such rights are rooted in the republican revolution of the late 18th century, and the Rights of Man movement. Today in the European system the creator is front and center; later exploiters are only secondary players.

France

During the 18th century France gradually lost the ability to restrict intellectual property. Before the Revolution, all books, printers and booksellers had to have a royal stamp of approval, called a "privilege". In return for their lucrative monopoly, the French guild of printers and booksellers helped the police to suppress anything that upset royal sensibilities or ran contrary to their interests. Still there were also a whole lot of underground printers who flooded the country with pirated, pornographic and seditious literature. And thousands of writers, most at the edge of starvation.

In 1777 the King threatened the monopoly by reducing the duration of publisher's privileges to the lifetime of the authors. Accordingly a writer's work would go into the public domain after his death and could be printed by anyone. The booksellers fought back by argumenting that, no authority could take their property from them and give it to someone else. Seven months later, in August 1789, the revolutionary government ended the privilege system and from that time on anyone could print anything. Early in 1790 Marie-Jean-Antoine-Nicolas de Caritat, Marquis de Condorcet proposed giving authors power over their own work lasting until ten years after their deaths. The proposal - the basis for France's first modern copyright law - passed in 1793.

Copyright Management and Control Systems: Post-Infringement

Post-infringement technologies allow the owners of copyrighted works to identify infringements and thus enhance enforcement of intellectual property rights and encompass systems such as:

Steganography

Applied to electronic files, steganography refers to the process of hiding information in files that can not be easily detected by users. Steganography can be used by intellectual property owners in a variety of ways. One is to insert into the file a "digital watermark" which can be used to prove that an infringing file was the creation of the copyright holder and not the pirate. Other possibilities are to encode a unique serial number into each authorized copy or file, enabling the owner to trace infringing copies to a particular source, or to store copyright management information.

Agents

Agents are programs that can implement specified commands automatically. Copyright owners can use agents to search the public spaces of the Internet to find infringing copies. Although the technology is not yet very well developed full-text search engines allow similar uses.

Copyright Litigation

While not every infringement will be the subject of litigation, the threat of litigation helps keep large pirate operations in check. It helps copyright owners obtain relief for specific acts of infringement and publicly warns others of the dangers of infringement.

Basics: Acquisition of Copyright

The laws of almost all countries provide that protection is independent of any formalities. Copyright protection then starts as soon as the work is created.

Operating the net: overview

The Net consists of thousands of thousands of governmental and private networks linked together. No legal authority determines how and where networks can be connected together, this is something the managers of networks have to agree about. So there is no way of ever gaining ultimate control of the Internet. Although each of these networks is operated and controlled by an organization, no single organization operates and controls the Net. Instead of a central authority governing the Net, several bodies assure the operability of the Net by developing and setting technical specifications for the Net and by the control of the technical key functions of the Net as the coordination of the domain name system and the allocation of IP numbers.

Originally, the Net was a research project funded and maintained by the US Government and developed in collaboration by scientists and engineers. As the standards developed for ensuring operability ensued from technical functionality, technical coordination gradually grew out of necessity and was restricted to a minimum and performed by volunteers.

Later, in the 1980s, those occupied with the development of technical specifications organized themselves under the umbrella of the Internet Society in virtual organizations as the Internet Engineering Task Force, which were neither officially established nor being based on other structures than mailing lists and commitment, but nonetheless still serve as task forces for the development of standards ensuring the interoperability on the Net.

Since the late 80s and the early 90s, with the enormous growth of the Net - which was promoted by the invention of Local Area Networks, the creation of the World Wide Web, the increased use of personal computers and the connecting of corporations to the Net, just to name a few - coordination of some technical key functions as the domain name system was handed over to corporations as Network Solutions Inc.

Since the year 2000, a new model for technical coordination has been emerging: Formerly performed by several bodies, technical coordination is transferred to a single non-governmental organization: the Internet Coordination of Assigned Numbers and Names.

Linking and Framing: Cases

Mormon Church v. Sandra and Jerald Tanner

In a ruling of December 1999, a federal judge in Utah temporarily barred two critics of the Mormon Church from posting on their website the Internet addresses of other sites featuring pirated copies of a Mormon text. The Judge said that it was likely that Sandra and Jerald Tanner had engaged in contributory copyright infringement when they posted the addresses of three Web sites that they knew, or should have known, contained the copies.

Universal Studios v. Movie-List

The website Movie-List, which features links to online, externally hosted movie trailers has been asked to completely refrain from linking to any of Universal Studio's servers containing the trailers as this would infringe copyright.

Acessing the Internet

The Net connections can be based on wire-line and wireless access technolgies.

Wire-line access

Wire-less access

copper wires

Satellites

coaxial cables

mobile terrestrial antennas

electric power lines

fixed terrestrial antennas

fiber-optic cables







Usually several kinds of network connections are employed at once. Generally speaking, when an E-mail message is sent it travels from the user's computer via copper wires or coaxial cables ISDN lines, etc., to an Internet Service Provider, from there, via fibre-optic cables, to the nearest Internet exchange, and on into a backbone network, tunneling across the continent und diving through submarine fibre-optic cables across the Atlantic to another Internet exchange, from there, via another backbone network and across another regional network to the Internet Service Provider of the supposed message recipient, from there via cables and wires of different bandwidth arriving at its destination, a workstation permanently connected to the Internet. Finally a sound or flashing icon informs your virtual neighbor that a new message has arrived.

Satellite communication

Although facing competition from fiber-optic cables as cost-effective solutions for broadband data transmission services, the space industry is gaining increasing importance in global communications. As computing, telephony, and audiovisual technologies converge, new wireless technologies are rapidly deployed occupying an increasing market share and accelerating the construction of high-speed networks.

Privatization of satellite communication

Until recently transnational satellite communication was provided exclusively by intergovernmental organizations as Intelsat, Intersputnik and Inmarsat.

Scheduled privatization of intergovernmental satellite consortia:

1979

158 nations (all members of the International Maritime Organization)

privatized since 1999

Eutelsat

1985

Nearly 50 European nations

2001



When Intelsat began to accumulate losses because of management failures and the increasing market share of fiber-optic cables, this organizational scheme came under attack. Lead by the USA, the Western industrialized countries successfully pressed for the privatization of all satellite consortia they are members of and for competition by private carriers.

As of February 2000, there are 2680 satellites in service. Within the next four years a few hundred will be added by the new private satellite systems. Most of these systems will be so-called Low Earth Orbit satellite systems, which are capable of providing global mobile data services on a high-speed level at low cost.

Because of such technological improvements and increasing competition, experts expect satellite-based broadband communication to be as common, cheap, and ubiquitous as satellite TV today within the next five or ten years.

Positions Towards the Future of Copyright in the "Digital Age"

With the development of new transmission, distribution and publishing technologies and the increasing digitalization of information copyright has become the subject of vigorous debate. Among the variety of attitudes towards the future of traditional copyright protection two main tendencies can be identified:

Eliminate Copyright

Anti-copyrightists believe that any intellectual property should be in the public domain and available for all to use. "Information wants to be free" and copyright restricts people's possibilities concerning the utilization of digital content. An enforced copyright will lead to a further digital divide as copyright creates unjust monopolies in the basic commodity of the "information age". Also the increased ease of copying effectively obviates copyright, which is a relict of the past and should be expunged.

Enlarge Copyright

Realizing the growing economic importance of intellectual property, especially the holders of copyright (in particular the big publishing, distribution and other core copyright industries) - and therefore recipients of the royalties - adhere to the idea of enlarging copyright. In their view the basic foundation of copyright - the response to the need to provide protection to authors so as to give them an incentive to invest the time and effort required to produce creative works - is also relevant in a digital environment.

Expert system

Expert systems are advanced computer programs that mimic the knowledge and reasoning capabilities of an expert in a particular discipline. Their creators strive to clone the expertise of one or several human specialists to develop a tool that can be used by the layman to solve difficult or ambiguous problems. Expert systems differ from conventional computer programs as they combine facts with rules that state relations between the facts to achieve a crude form of reasoning analogous to artificial intelligence. The three main elements of expert systems are: (1) an interface which allows interaction between the system and the user, (2) a database (also called the knowledge base) which consists of axioms and rules, and (3) the inference engine, a computer program that executes the inference-making process. The disadvantage of rule-based expert systems is that they cannot handle unanticipated events, as every condition that may be encountered must be described by a rule. They also remain limited to narrow problem domains such as troubleshooting malfunctioning equipment or medical image interpretation, but still have the advantage of being much lower in costs compared with paying an expert or a team of specialists.

Gottfried Wilhelm von Leibniz

b. July 1, 1646, Leipzig
d. November 14, 1716, Hannover, Hanover

German philosopher, mathematician, and political adviser, important both as a metaphysician and as a logician and distinguished also for his independent invention of the differential and integral calculus. 1661, he entered the University of Leipzig as a law student; there he came into contact with the thought of men who had revolutionized science and philosophy--men such as Galileo, Francis Bacon, Thomas Hobbes, and René Descartes. In 1666 he wrote De Arte Combinatoria ("On the Art of Combination"), in which he formulated a model that is the theoretical ancestor of some modern computers.

Machine language

Initially computer programmers had to write instructions in machine language. This coded language, which can be understood and executed directly by the computer without conversion or translation, consists of binary digits representing operation codes and memory addresses. Because it is made up of strings of 1s and 0s, machine language is difficult for humans to use.

Economic rights

The economic rights (besides moral rights and in some cases also neighboring rights) granted to the owners of copyright usually include 1) copying or reproducing a work, 2) performing a work in public, 3) making a sound recording of a work, 4) making a motion picture of a work, 5) broadcasting a work, 6) translating a work and 7) adapting a work. Under certain national laws some of these rights are not exclusive rights of authorization but in specific cases, merely rights to remuneration.

Mark

A mark (trademark or service mark) is "... a sign, or a combination of signs, capable of distinguishing the goods or services of one undertaking from those of other undertakings. The sign may particularly consist of one or more distinctive words, letters, numbers, drawings or pictures, emblems, colors or combinations of colors, or may be three-dimensional..." (WIPO) To be protected a mark must be registered in a government office whereby generally the duration is limited in time, but can be periodically (usually every 10 years) renewed.

Napoleon

Napoleon I. (1769-1821) was French King from 1804-1815.
He is regarded as the master of propaganda and disinformation of his time. Not only did he play his game with his own people but also with all European nations. And it worked as long as he managed to keep up his propaganda and the image of the winner.
Part of his already nearly commercial ads was that his name's "N" was painted everywhere.
Napoleon understood the fact that people believe what they want to believe - and he gave them images and stories to believe. He was extraordinary good in black propaganda.
Censorship was an element of his politics, accompanied by a tremendous amount of positive images about himself.
But his enemies - like the British - used him as a negative image, the reincarnation of the evil (a strategy still very popular in the Gulf-War and the Kosovo-War) (see Taylor, Munitions of the Mind p. 156/157).
