The Centripetal Network: How the Internet Holds Itself Together, and the Forces Tearing It Apart

Two forces are in tension as the Internet evolves. One pushes toward interconnected common platforms; the other pulls toward fragmentation and proprietary alternatives. Their interplay drives many of the contentious issues in cyberlaw, intellectual property, and telecommunications policy, including the fight over network neutrality for broadband providers, debates over global Internet governance, and battles over copyright online. These are more than just conflicts between incumbents and innovators, or between openness and deregulation. Their roots lie in the fundamental dynamics of interconnected networks. Fortunately, there is an interdisciplinary literature on network properties, albeit one virtually unknown to legal scholars. The emerging field of network formation theory explains the pressures threatening to pull the Internet apart, and suggests responses. The Internet as we know it is surprisingly fragile. To continue the extraordinary outpouring of creativity and innovation that the Internet fosters, policy-makers must protect its composite structure against both fragmentation and excessive concentration of power. This paper, the first to apply network formation models to Internet law, shows how the Internet pulls itself together as a coherent whole. This very process, however, creates and magnifies imbalances that encourage balkanization. By understanding how networks behave, governments and other legal decision-makers can avoid unintended consequences and target their actions appropriately. A network-theoretic perspective holds great promise to inform the law and policy of the information economy

Bandwidth is political: Reachability in the public internet

The global public Internet faces a growing but little studied threat from the use of intrusive traffic management practices by both wholesale and retail Internet service providers. Unlike research concerned with bandwidth and traffic growth, this study shifts the risk analysis away from capacity issues to focus on performance standards for interconnection and data reachability. The long-term health of the Internet is framed in terms of “data reachability” – the principle that any end-user can reach any part of the Internet without encountering arbitrary actions on the part of a network operator that might block or degrade transmission. Risks to reachability are framed in terms of both systematic traffic management practices and “de-peering,” a more aggressive tactic practised by Tier-1 network operators to resolve disputes or punish rivals. De-peering is examined as an extension of retail network management practices that include the growing use of deep packet inspection (DPI) technology for traffic-shaping. De-peering can also be viewed as a close relative of Net Neutrality, to the extent that both concepts reflect arbitrary practices that interfere with the reliable flow of data packets across the Internet. In jurisdictional terms, however, de-peering poses a qualitatively different set of risks to stakeholders and end-users, as well as qualitatively different challenges to policymakers. It is argued here that risks to data unreachability represent the next stage in debates about the health and sustainability of the global Internet. The study includes a detailed examination of the development of the Internet’s enabling technologies; the evolution of telecommunications regulation in Canada and the United States, and its impact on Internet governance; and an analysis of the role played by commercialization and privatization in the growth of risks to data reachability

Status of This Memo Reflections on Internet Transparency

This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The IETF Trust (2007). This document provides a review of previous IAB statements on Internet transparency, as well a discussion of new transparency issues. Far from having lessened in relevance, technical implications of intentionally or inadvertently impeding network transparency play a critical role in the Internet’s ability to support innovation and global communication. This document provides some specific illustrations of those potential impacts
