Low tech connections into the ARPA internet : the RawPacket split-gateway

This report describes a "low technology" method for connecting into the ARPA Internet. The use of a RawPacket interface in a system which supoprts IP makes possible the construction of a split-gateway between two hosts. The RawPacket interface permits a user-level process to introduce arbitrary packets into the IP layer, resulting in a virtual network interface. Since the split-gateway is implemented using a RawPacket interface, two networks may be connected together using a convenient medium which does not require explicit kernel support. Hence, split-gateways are well-suited for use as stub-gateways, connecting a local network to a long-haul network such as the ARPA backbone. In particular, the split-gateway discussed in this report achieves a reasonable level of connectivity for a comparatively small expenditure.This report details how the RawPacket software and split-gateways are implemented. In addition, various daemon configurations are presented, modifications to the operating environment are discussed, and some performance measurements are given

Governing by internet architecture

In the past thirty years, the exponential rise in the number of Internet users around the word and the intensive use of the digital networks have brought to light crucial political issues. Internet is now the object of regulations. Namely, it is a policy domain. Yet, its own architecture represents a new regulative structure, one deeply affecting politics and everyday life. This article considers some of the main transformations of the Internet induced by privatization and militarization processes, as well as their consequences on societies and human beings.En los últimos treinta años ha crecido de manera exponencial el número de usuarios de Internet alrededor del mundo y el uso intensivo de conexiones digitales ha traído a la luz cuestiones políticas cruciales. Internet es ahora objeto de regulaciones. Es decir, es un ámbito de la política. Aún su propia arquitectura representa una nueva estructura reguladora, que afecta profundamente la política y la vida cotidiana. Este artículo considera algunas de las principales transformaciones de Internet inducida por procesos de privatización y militarización, como también sus consecuencias en las sociedades y en los seres humanos

The role of non-state actors in regime formation: Case study on Internet governance.

Many scholars argue that the Internet is a symbol of globalization and avoidance of state control. The Internet governance negotiations, which aims to establish an international regime for the Internet, is conducted through a multi-stakeholder setting associated with extensive involvement of non-state actors. This has been viewed as an indicator for a \u27diminishing state role\u27 in international relations; particularly, formation of international regimes. This study indicates that the role of states does not diminish in regime formation. States, especially great powers, are the main actors that set international principles, norms, rules and decision-making procedures. They create regimes in order to regulate international behavior as to global sectors, including the Internet. States deliberately enable certain non-state actors to participate in regime formation and governance of some global sectors, based on conscious perception of the utility and usefulness of such participation

How robust are distributed systems

A distributed system is made up of large numbers of components operating asynchronously from one another and hence with imcomplete and inaccurate views of one another's state. Load fluctuations are common as new tasks arrive and active tasks terminate. Jointly, these aspects make it nearly impossible to arrive at detailed predictions for a system's behavior. It is important to the successful use of distributed systems in situations in which humans cannot provide the sorts of predictable realtime responsiveness of a computer, that the system be robust. The technology of today can too easily be affected by worn programs or by seemingly trivial mechanisms that, for example, can trigger stock market disasters. Inventors of a technology have an obligation to overcome flaws that can exact a human cost. A set of principles for guiding solutions to distributed computing problems is presented

Monkeys, typewriters and networks: the internet in the light of the theory of accidental excellence

Viewed in the light of the theory of accidental excellence, there is much to suggest that the success of the Internet and its various protocols derives from a communications technology accident, or better, a series of accidents. In the early 1990s, many experts still saw the Internet as an academic toy that would soon vanish into thin air again. The Internet probably gained its reputation as an academic toy largely because it violated the basic principles of traditional communications networks. The quarrel about paradigms that erupted in the 1970s between the telephony world and the newly emerging Internet community was not, however, only about transmission technology doctrines. It was also about the question – still unresolved today – as to who actually governs the flow of information: the operators or the users of the network? The paper first describes various network architectures in relation to the communication cultures expressed in their make-up. It then examines the creative environment found at the nodes of the network, whose coincidental importance for the Internet boom must not be forgotten. Finally, the example of Usenet is taken to look at the kind of regulatory practices that have emerged in the communications services provided within the framework of a decentralised network architecture. --

The Political Nature of TCP/IP

Despite the importance of the Internet in the modern world, many users and even policy makers don’t have a necessary historical or technical grasp of the technology behind it. In the spirit of addressing this issue, this thesis attempts to shed light on the historical, political, and technical context of TCP/IP. TCP/IP is the Internet Protocol Suite, a primary piece of Internet architecture with a well-documented history. After at technical overview, detailing the main function of TCP/IP, I examine aspects of the social and developmental record of this technology using STS theoretical approaches such as Hughesian systems theory, Social Construction of Technology (SCOT), and Langdon Winner’s brand of technological determinism. Key points in TCP/IP evolution, when viewed from an STS perspective, illuminate the varied reasons behind decisions and development of the technology. For example, as detailed in this paper, both technical and political motivations were behind the architectural politics built into TCP/IP in the 1970s, and similar motivations spurred the rejection of OSI protocols by Internet developers two decades later. Armed with resultant contextual understanding of previous TCP/IP developments, a few possible directions (both political and technical) in contemporary and future Internet development are then explored, such as the slow migration to IPv6 and the meaning of network neutrality

Internet Governance: the State of Play

The Global Forum on Internet Governance held by the UNICT Task Force in New York on 25-26 March concluded that Internet governance issues were many and complex. The Secretary-General's Working Group on Internet Governance will have to map out and navigate this complex terrain as it makes recommendations to the World Summit on an Information Society in 2005. To assist in this process, the Forum recommended, in the words of the Deputy Secretary-General of the United Nations at the closing session, that a matrix be developed "of all issues of Internet governance addressed by multilateral institutions, including gaps and concerns, to assist the Secretary-General in moving forward the agenda on these issues." This paper takes up the Deputy Secretary-General's challenge. It is an analysis of the state of play in Internet governance in different forums, with a view to showing: (1) what issues are being addressed (2) by whom, (3) what are the types of consideration that these issues receive and (4) what issues are not adequately addressed
