In Search of Reliable Internet Measurement Data Newspapers and magazines frequently report growth rates of Internet usage, number of users, hosts, and domains that seem to be beyond all expectations. Growth rates are expected to accelerate exponentially. However, Internet measurement data are anything thant reliable and often quite fantastic constructs, that are nevertheless jumped upon by many media and decision makers because the technical difficulties in measuring Internet growth or usage are make reliable measurement techniques impossible. Equally, predictions that the Internet is about to collapse lack any foundation whatsoever. The researchers at the Internet Performance Measurement and Analysis Project (IPMA) compiled a list of news items about Internet performance and statistics and a few responses to them by engineers. Size and Growth In fact, "today's Internet industry lacks any ability to evaluate trends, identity performance problems beyond the boundary of a single ISP (Internet service provider, M. S.), or prepare systematically for the growing expectations of its users. Historic or current data about traffic on the Internet infrastructure, maps depicting ... there is plenty of measurement occurring, albeit of questionable quality", says K. C. Claffy in his paper Internet measurement and data analysis: topology, workload, performance and routing statistics (http://www.caida.org/Papers/Nae/, Dec 6, 1999). Claffy is not an average researcher; he founded the well-known Cooperative Association for Internet Data Analysis (CAIDA). So his statement is a slap in the face of all market researchers stating otherwise. In a certain sense this is ridiculous, because since the inception of the ARPANet, the offspring of the Internet, network measurement was an important task. The very first ARPANet site was established at the University of California, Los Angeles, and intended to be the measurement site. There, Leonard Kleinrock further on worked on the development of measurement techniques used to monitor the performance of the ARPANet (cf. Michael and Ronda Hauben, Netizens: On the History and Impact of the Net). And in October 1991, in the name of the Internet Activities Board Vinton Cerf proposed guidelines for researchers considering measurement experiments on the Internet stated that the measurement of the Internet. This was due to two reasons. First, measurement would be critical for future development, evolution and deployment planning. Second, Internet-wide activities have the potential to interfere with normal operation and must be planned with care and made widely known beforehand. So what are the reasons for this inability to evaluate trends, identity performance problems beyond the boundary of a single ISP? First, in early 1995, almost simultaneously with the worldwide introduction of the World Wide Web, the transition of the stewardship role of the National Science Foundation over the Internet into a competitive industry (bluntly spoken: its privatization) left no framework for adequate tracking and monitoring of the Internet. The early ISPs were not very interested in gathering and analyzing network performance data, they were struggling to meet demands of their rapidly increasing customers. Secondly, we are just beginning to develop reliable tools for quality measurement and analysis of bandwidth or performance. CAIDA aims at developing such tools. "There are many estimates of the size and growth rate of the Internet that are either implausible, or inconsistent, or even clearly wrong", K. G. Coffman and Andrew, both members of different departments of AT & T Labs-Research, state something similar in their paper The Size and Growth Rate of the Internet, published in First Monday. There are some sources containing seemingly contradictory information on the size and growth rate of the Internet, but "there is no comprehensive source for information". They take a well-informed and refreshing look at efforts undertaken for measuring the Internet and dismantle several misunderstandings leading to incorrect measurements and estimations. Some measurements have such large error margins that you might better call them estimations, to say the least. This is partly due to the fact that data are not disclosed by every carrier and only fragmentarily available. What is measured and what methods are used? Many studies are devoted to the number of users; others look at the number of computers connected to the Internet or count IP addresses. Coffman and Odlyzko focus on the sizes of networks and the traffic they carry to answer questions about the size and the growth of the Internet. You get the clue of their focus when you bear in mind that the Internet is just one of many networks of networks; it is only a part of the universe of computer networks. Additionally, the Internet has public (unrestricted) and private (restricted) areas. Most studies consider only the public Internet, Coffman and Odlyzko consider the long-distance private line networks too: the corporate networks, the Intranets, because they are convinced (that means their assertion is put forward, but not accompanied by empirical data) that "the evolution of the Internet in the next few years is likely to be determined by those private networks, especially by the rate at which they are replaced by VPNs (Virtual Private Networks) running over the public Internet. Thus it is important to understand how large they are and how they behave." Coffman and Odlyzko check other estimates by considering the traffic generated by residential users accessing the Internet with a modem, traffic through public peering points (statistics for them are available through CAIDA and the National Laboratory for Applied Network Research), and calculating the bandwidth capacity for each of the major US providers of backbone services. They compare the public Internet to private line networks and offer interesting findings. The public Internet is currently far smaller, in both capacity and traffic, than the switched voice network (with an effective bandwidth of 75 Gbps at December 1997), but the private line networks are considerably larger in aggregate capacity than the Internet: about as large as the voice network in the U. S. (with an effective bandwidth of about 330 Gbps at December 1997), they carry less traffic. On the other hand, the growth rate of traffic on the public Internet, while lower than is often cited, is still about 100% per year, much higher than for traffic on other networks. Hence, if present growth trends continue, data traffic in the U. S. will overtake voice traffic around the year 2002 and will be dominated by the Internet. In the future, growth in Internet traffic will predominantly derive from people staying longer and from multimedia applications, because they consume more bandwidth, both are the reason for unanticipated amounts of data traffic. Hosts The Internet Software Consortium's Internet Domain Survey is one of the most known efforts to count the number of hosts on the Internet. Happily the ISC informs us extensively about the methods used for measurements, a policy quite rare on the Web. For the most recent survey the number of IP addresses that have been assigned a name were counted. At first sight it looks simple to get the accurate number of hosts, but practically an assigned IP address does not automatically correspond an existing host. In order to find out, you have to send a kind of message to the host in question and wait for a reply. You do this with the PING utility. (For further explanations look here: Art. PING, in: Connected: An Internet Encyclopaedia) But to do this for every registered IP address is an arduous task, so ISC just pings a 1% sample of all hosts found and make a projection to all pingable hosts. That is ISC's new method; its old method, still used by RIPE, has been to count the number of domain names that had IP addresses assigned to them, a method that proved to be not very useful because a significant number of hosts restricts download access to their domain data. Despite the small sample, this method has at least one flaw: ISC's researchers just take network numbers into account that have been entered into the tables of the IN-ADDR.ARPA domain, and it is possible that not all providers know of these tables. A similar method is used for Telcordia's Netsizer. Internet Weather Like daily weather, traffic on the Internet, the conditions for data flows, are monitored too, hence called Internet weather. One of the most famous Internet weather report is from The Matrix, Inc. Another one is the Internet Traffic Report displaying traffic in values between 0 and 100 (high values indicate fast and reliable connections). For weather monitoring response ratings from servers all over the world are used. The method used is to "ping" servers (as for host counts, e. g.) and to compare response times to past ones and to response times of servers in the same reach. Hits, Page Views, Visits, and Users Let us take a look at how these hot lists of most visited Web sites may be compiled. I say, may be, because the methods used for data retrieval are mostly not fully disclosed. For some years it was seemingly common sense to report requested files from a Web site, so called "hits". A method not very useful, because a document can consist of several files: graphics, text, etc. Just compile a document from some text and some twenty flashy graphical files, put it on the Web and you get twenty-one hits per visit; the more graphics you add, the more hits and traffic (not automatically to your Web site) you generate. In the meantime page views, also called page impressions are preferred, which are said to avoid these flaws. But even page views are not reliable. Users might share computers and corresponding IP addresses and host names with others, she/he might access not the site, but a cached copy from the Web browser or from the ISP's proxy server. So the server might receive just one page request although several users viewed a document. Especially the editors of some electronic journals (e-journals) rely on page views as a kind of ratings or circulation measure, Rick Marin reports in the New York Times. Click-through rates - a quantitative measure - are used as a substitute for something of intrinsically qualitative nature: the importance of a column to its readers, e. g. They may read a journal just for a special column and not mind about the journal's other contents. Deleting this column because of not receiving enough visits may cause these readers to turn their backs on their journal. More advanced, but just slightly better at best, is counting visits, the access of several pages of a Web site during one session. The problems already mentioned apply here too. To avoid them, newspapers, e.g., establish registration services, which require password authentication and therefore prove to be a kind of access obstacle. But there is a different reason for these services. For content providers users are virtual users, not unique persons, because, as already mentioned, computers and IP addresses can be shared and the Internet is a client-server system; in a certain sense, in fact computers communicate with each other. Therefore many content providers are eager to get to know more about users accessing their sites. On-line registration forms or WWW user surveys are obvious methods of collecting additional data, sure. But you cannot be sure that information given by users is reliable, you can just rely on the fact that somebody visited your Web site. Despite these obstacles, companies increasingly use data capturing. As with registration services cookies come here into play. For If you like to play around with Internet statistics instead, you can use Robert Orenstein's Web Statistics Generator to make irresponsible predictions or visit the Internet Index, an occasional collection of seemingly statistical facts about the Internet. Measuring the Density of IP Addresses Measuring the Density of IP Addresses or domain names makes the geography of the Internet visible. So where on earth is the most density of IP addresses or domain names? There is no global study about the Internet's geographical patterns available yet, but some regional studies can be found. The Urban Research Initiative and Martin Dodge and Narushige Shiode from the Centre for Advanced Spatial Analysis at the University College London have mapped the Internet address space of New York, Los Angeles and the United Kingdom (http://www.geog.ucl.ac.uk/casa/martin/internetspace/paper/telecom.html and http://www.geog.ucl.ac.uk/casa/martin/internetspace/paper/gisruk98.html). Dodge and Shiode used data on the ownership of IP addresses from RIPE, Europe's most important registry for Internet numbers.

The Kosovo-Crisis During the Kosovo Crisis and during the war that followed, and probably also after it, all sides of the conflict were manipulating their people and others as well, whenever they could. Some of the propaganda shown on TV was as primitive as in World War II, others were subtler. This propaganda started by telling the history of the geographic point of discussion from the own point of view, it went on with the interpretation of the motives of the enemy and finally came to censorship, manipulation of the number of victims ( for more information see: http://www.oneworld.org/index_oc/kosovo/kadare.html , spreading of atrocity stories and so on. Many journalists and scientists are still working to detect more propaganda and disinformation stories. An interesting detail about this war was that more people than ever before took their information about the war out of the internet. In part this had to do with the biased TV-reports on all sides. All parties put their ideas and perspectives in the net, so one could get an overview of the different thoughts and types of disinformation. One of the big lies of NATO was the numbers of destroyed military facilities in Serbia. After the war the numbers had to be corrected down to a ridiculous number of about 13 destroyed tanks. At the same time the numbers of civilian victims turned out to be much higher than NATO had admitted in the first line. The method how European and American people had been persuaded to support the NATO-bombings was the promise to bomb only targets of the military or military-related facilities. Nearly every day NATO had to stretch this interpretation, as many civilian houses got destroyed. A cynical word was created for this kind of excuse: collateral damage. The Serbs were not better than Western governments and media, which worked together closely. Serb TV showed the bombed targets and compared persons like Bill Clinton to Adolf Hitler and called the NATO fascist. On the other hand pictures from the situation in Kosov@ were left out in their reports.

Virtual body and data body The result of this informatisation is the creation of a virtual body which is the exterior of a man or woman's social existence. It plays the same role that the physical body, except located in virtual space (it has no real location). The virtual body holds a certain emancipatory potential. It allows us to go to places and to do things which in the physical world would be impossible. It does not have the weight of the physical body, and is less conditioned by physical laws. It therefore allows one to create an identity of one's own, with much less restrictions than would apply in the physical world. But this new freedom has a price. In the shadow of virtualisation, the data body has emerged. The data body is a virtual body which is composed of the files connected to an individual. As the Critical Art Ensemble observe in their book Flesh Machine, the data body is the "fascist sibling" of the virtual body; it is " a much more highly developed virtual form, and one that exists in complete service to the corporate and police state." The virtual character of the data body means that social regulation that applies to the real body is absent. While there are limits to the manipulation and exploitation of the real body (even if these limits are not respected everywhere), there is little regulation concerning the manipulation and exploitation of the data body, although the manipulation of the data body is much easier to perform than that of the real body. The seizure of the data body from outside the concerned individual is often undetected as it has become part of the basic structure of an informatised society. But data bodies serve as raw material for the "New Economy". Both business and governments claim access to data bodies. Power can be exercised, and democratic decision-taking procedures bypassed by seizing data bodies. This totalitarian potential of the data body makes the data body a deeply problematic phenomenon that calls for an understanding of data as social construction rather than as something representative of an objective reality. How data bodies are generated, what happens to them and who has control over them is therefore a highly relevant political question.

Data bunkers Personal data are collected, appropriated, processed and used for commercial purposes on a global scale. In order for such a global system to operate smoothly, there a server nodes at which the data streams converge. Among the foremost of these are the data bases of credit card companies, whose operation has long depended on global networking. On top of credit card companies such as Visa, American Express, Master Card, and others. It would be erroneous to believe that the primary purpose of business of these companies is the provision of credit, and the facilitation of credit information for sale transactions. In fact, Information means much more than just credit information. In an advertisement of 1982, American Express described itself in these terms: ""Our product is information ...Information that charges airline tickets, hotel rooms, dining out, the newest fashions ...information that grows money funds buys and sells equities ...information that pays life insurance annuities ...information that schedules entertainment on cable television and electronically guards houses ...information that changes kroners into guilders and figures tax rates in Bermuda ..." Information has become something like the gospel of the New Economy, a doctrine of salvation - the life blood of society, as Bill Gates expresses it. But behind information there are always data that need to be generated and collected. Because of the critical importance of data to the economy, their possession amounts to power and their loss can cause tremendous damage. The data industry therefore locates its data warehouses behind fortifications that bar physical or electronic access. Such structures are somewhat like a digital reconstruction of the medieval fortress Large amounts of data are concentrated in fortress-like structures, in data bunkers. As the Critical Art Ensemble argue in Electronic Civil Disobedience: "The bunker is the foundation of homogeneity, and allows only a singular action within a given situation." All activities within data bunker revolve around the same principle of calculation. Calculation is the predominant mode of thinking in data-driven societies, and it reaches its greatest density inside data bunkers. However, calculation is not a politically neutral activity, as it provides the rational basis - and therefore the formal legitimisation most every decision taken. Data bunkers therefore have an essentially conservative political function, and function to maintain and strengthen the given social structures.

Anonymity "Freedom of anonymous speech is an essential component of free speech." Ian Goldberg/David Wagner, TAZ Servers and the Rewebber Network: Enabling Anonymous Publishing on the World Wide Web, in: First Monday 3,4, 1999 Someone wants to hide one's identity, to remain anonymous, if s/he fears to be holding accountable for something, say, a publication, that is considered to be prohibited. Anonymous publishing has a long tradition in European history. Writers of erotic literature or pamphlets, e. g., preferred to use pseudonyms or publish anonymously. During the Enlightenment books as d'Alembert's and Diderot's famous Encyclopaedia were printed and distributed secretly. Today Book Locker, a company selling electronic books, renews this tradition by allowing to post writings anonymously, to publish without the threat of being perishing for it. Sometimes anonymity is a precondition for reporting human rights abuses. For example, investigative journalists and regime critics may rely on anonymity. But we do not have to look that far; even you might need or use anonymity sometimes, say, when you are a woman wanting to avoid sexual harassment in chat rooms. The original design of the Net, as far as it is preserved, offers a relatively high degree of privacy, because due to the client-server model all what is known about you is a report of the machine from which information was, respectively is requested. But this design of the Net interferes with the wish of corporations to know you, even to know more about you than you want them to know. What is euphemistically called customer relationship management systems means the collection, compilation and analysis of personal information about you by others. In 1997 America Online member Timothy McVeigh, a Navy employee, made his homosexuality publicly known in a short autobiographical sketch. Another Navy employee reading this sketch informed the Navy. America Online revealed McVeigh's identity to the Navy, who discharged McVeigh. As the consequence of a court ruling on that case, Timothy McVeigh was allowed to return to the Navy. Sometimes anonymity really matters. On the Net you still have several possibilities to remain anonymous. You may visit web sites via an anonymizing service. You might use a Web mail account (given the personal information given to the web mail service provider is not true) or you might use an anonymous remailing service which strips off the headers of your mail to make it impossible to identify the sender and forward your message. Used in combination with encryption tools and technologies like FreeHaven or Publius anonymous messaging services provide a powerful tool for countering censorship. In Germany, in 1515, printers had to swear not to print or distribute any publication bypassing the councilmen. Today repressive regimes, such as China and Burma, and democratic governments, such as the France and Great Britain, alike impose or already have imposed laws against anonymous publishing on the Net. Anonymity might be used for abuses, that is true, but "the burden of proof rests with those who would seek to limit it. (Rob Kling, Ya-ching Lee, Al Teich, Mark S. Frankel, Assessing Anonymous Communication on the Internet: Policy Deliberations, in: The Information Society, 1999).

Intellectual Property: A Definition Intellectual property, very generally, relates to the output, which result from intellectual activity in the industrial, scientific, literary and artistic fields. Traditionally intellectual property is divided into two branches: 1) Industrial Property a) Inventions b) Marks (trademarks and service marks) c) Industrial designs d) Unfair competition (trade secrets) e) Geographical indications (indications of source and appellations of origin) 2) Copyright The protection of intellectual property is guaranteed through a variety of laws, which grant the creators of intellectual goods, and services certain time-limited rights to control the use made of their products. Those rights apply to the intellectual creation as such, and not to the physical object in which the work may be embodied.

2000 A.D. 2000 Convergence of telephony, audiovisual technologies and computing Digital technologies are used to combine previously separated communication and media systems such as telephony, audiovisual technologies and computing to new services and technologies, thus forming extensions of existing communication systems and resulting in fundamentally new communication systems. This is what is meant by today's new buzzwords "multimedia" and "convergence". Classical dichotomies as the one of computing and telephony and traditional categorizations no longer apply, because these new services no longer fit traditional categories. Convergence and Regulatory Institutions Digital technology permits the integration of telecommunications with computing and audiovisual technologies. New services that extend existing communication systems emerge. The convergence of communication and media systems corresponds to a convergence of corporations. Recently, America Online, the world's largest online service provider, merged with Time Warner, the world's largest media corporation. For such corporations the classical approach to regulation - separate institutions regulate separate markets - is no longer appropriate, because the institutions' activities necessarily overlap. The current challenges posed to these institutions are not solely due to the convergence of communication and media systems made possible by digital technologies; they are also due to the liberalization and internationalization of the electronic communications sector. For regulation to be successful, new categorizations and supranational agreements are needed. For further information on this issue see Natascha Just and Michael Latzer, The European Policy Response to Convergence with Special Consideration of Competition Policy and Market Power Control, http://www.soe.oeaw.ac.at/workpap.htm or http://www.soe.oeaw.ac.at/WP01JustLatzer.doc.

Transparent customers. Direct marketing online This process works even better on the Internet because of the latter's interactive nature. "The Internet is a dream to direct marketers", said Wil Lansing, CEO of the American retailer Fingerhut Companies. Many services require you to register online, requiring users to provide as much information about them as possible. And in addition, the Internet is fast, cheap and used by people who tend to be young and on the search for something interesting. Many web sites also are equipped with user tracking technology that registers a users behaviour and preferences during a visit. For example, user tracking technology is capable of identifying the equipment and software employed by a user, as well as movements on the website, visit of links etc. Normally such information is anonymous, but can be personalised when it is coupled with online registration, or when personal identifcation has been obtained from other sources. Registration is often a prerequisite not just for obtaining a free web mail account, but also for other services, such as personalised start pages. Based on the information provided by user, the start page will then include advertisements and commercial offers that correspond to the users profile, or to the user's activity on the website. One frequent way of obtaining such personal information of a user is by offering free web mail accounts offered by a great many companies, internet providers and web portals (e.g. Microsoft, Yahoo, Netscape and many others). In most cases, users get "free" accounts in return for submitting personal information and agreeing to receive marketing mails. Free web mail accounts are a simple and effective direct marketing and data capturing strategy which is, however, rarely understood as such. However, the alliances formed between direct advertising and marketing agencies on the one hand, and web mail providers on the other hand, such as the one between DoubleClick and Yahoo, show the common logic of data capturing and direct marketing. The alliance between DoubleClick and Yahoo eventually attracted the US largest direct marketing agency, Abacus Direct, who ended up buying DoubleClick. However, the intention of collecting users personal data and create consumer profiles based on online behaviour can also take on more creative and playful forms. One such example is sixdegrees.com. This is a networking site based on the assumption that everybody on the planet is connected to everybody else by a chain of six people at most. The site offers users to get to know a lot of new people, the friends of their friends of their friends, for example, and if they try hard enough, eventually Warren Beatty or Claudia Schiffer. But of course, in order to make the whole game more useful for marketing purposes, users are encouraged to join groups which share common interests, which are identical with marketing categories ranging from arts and entertainment to travel and holiday. Evidently, the game becomes more interesting the more new people a user brings into the network. What seems to be fun for the 18 to 24 year old college student customer segment targeted by sixdegrees is, of course, real business. While users entertain themselves they are being carefully profiled. After all, data of young people who can be expected to be relatively affluent one day are worth more than money. The particular way in which sites such as sixdegrees.com and others are structured mean that not only to users provide initial information about them, but also that this information is constantly updated and therefore becomes even more valuable. Consequently, many free online services or web mail providers cancel a user's account if it has not been uses for some time. There are also other online services which offer free services in return for personal information which is then used for marketing purposes, e.g. Yahoo's Geocities, where users may maintain their own free websites, Bigfoot, where people are offered a free e-mail address for life, that acts as a relais whenever a customer's residence or e-mail address changes. In this way, of course, the marketers can identify friendship and other social networks, and turn this knowledge into a marketing advantage. People finders such as WhoWhere? operate along similar lines. A further way of collecting consumer data that has recently become popular is by offering free PCs. Users are provided with a PC for free or for very little money, and in return commit themselves to using certain services rather than others (e.g. a particular internet provider), providing information about themselves, and agree to have their online behaviour monitored by the company providing the PC, so that accurate user profiles can be compiled. For example, the Free PC Network offers advertisers user profiles containing "over 60 individual demographics". There are literally thousands of variations of how a user's data are extracted and commercialised when online. Usually this happens quietly in the background. A good inside view of the world of direct marketing can be gained at the website of the American Direct Marketing Association and the Federation of European Direct Marketing.

Bandwidth The bandwidth of a transmitted communications signal is a measure of the range of frequencies the signal occupies. The term is also used in reference to the frequency-response characteristics of a communications receiving system. All transmitted signals, whether analog or digital, have a certain bandwidth. The same is true of receiving systems. Generally speaking, bandwidth is directly proportional to the amount of data transmitted or received per unit time. In a qualitative sense, bandwidth is proportional to the complexity of the data for a given level of system performance. For example, it takes more bandwidth to download a photograph in one second than it takes to download a page of text in one second. Large sound files, computer programs, and animated videos require still more bandwidth for acceptable system performance. Virtual reality (VR) and full-length three-dimensional audio/visual presentations require the most bandwidth of all. In digital systems, bandwidth is data speed in bits per second (bps).

ARPAnet ARPAnet was the small network of individual computers connected by leased lines that marked the beginning of today's global data networks. Being an experimental network mainly serving the purpose to test the feasibility of wide area networks, the possibility of remote computing, it was created for resource sharing between research institutions, not for messaging services like E-mail. Although research was sponsored by US military, ARPAnet was not designed for directly martial use but to support military-related research. In 1969 ARPANET went online and links the first two computers, one of them located at the University of California, Los Angeles, the other at the Stanford Research Institute. But ARPAnet has not become widely accepted before it was demonstrated in action to a public of computer experts at the First International Conference on Computers and Communication in Washington, D. C. in 1972. Before it was decommissioned in 1990, NSFnet, a network of scientific and academic computers funded by the National Science Foundation, and a separate new military network went online in 1986. In 1988 the first private Internet service providers offered a general public access to NSFnet. Beginning in 1995, after having become the backbone of the Internet in the USA, NSFnet was turned over to a consortium of commercial backbone providers. This and the launch of the World Wide Web added to the success of the global data network we call the Net. In the USA commercial users already outnumbered military and academic users in 1994. Despite the rapid growth of the Net, most computers linked to it are still located in the United States.
