Cloud Computing, Contractibility, And Network Architecture, Christopher S. Yoo

All Faculty Scholarship

The emergence of the cloud is heightening the demands on the network in terms of bandwidth, ubiquity, reliability, latency, and route control. Unfortunately, the current architecture was not designed to offer full support for all of these services or to permit money to flow through it. Instead of modifying or adding specific services, the architecture could redesigned to make Internet services contractible by making the relevant information associated with these services both observable and verifiable. Indeed, several on-going research programs are exploring such strategies, including the NSF’s NEBULA, eXpressive Internet Architecture (XIA), ChoiceNet, and the IEEE’s Intercloud projects.

Cyber Espionage Or Cyber War?: International Law, Domestic Law, And Self-Protective Measures, Christopher S. Yoo

All Faculty Scholarship

Scholars have spent considerable effort determining how the law of war (particularly jus ad bellum and jus in bello) applies to cyber conflicts, epitomized by the Tallinn Manual on the International Law Applicable to Cyber Warfare. Many prominent cyber operations fall outside the law of war, including the surveillance programs that Edward Snowden has alleged were conducted by the National Security Agency, the distributed denial of service attacks launched against Estonia and Georgia in 2007 and 2008, the 2008 Stuxnet virus designed to hinder the Iranian nuclear program, and the unrestricted cyber warfare described in the 1999 book by …

A Market-Oriented Analysis Of The 'Terminating Access Monopoly' Concept, Jonathan E. Nuechterlein, Christopher S. Yoo

All Faculty Scholarship

Policymakers have long invoked the concept of a “terminating access monopoly” to inform communications policy. Roughly speaking, the concept holds that a consumer-facing network provider, no matter how small or how subject to retail competition, generally possesses monopoly power vis-à-vis third-party senders of communications traffic to its customers. Regulators and advocates have routinely cited that concern to justify regulatory intervention in a variety of contexts where the regulated party may or may not have possessed market power in any relevant retail market.

Despite the centrality of the terminating access monopoly to modern communications policy, there is surprisingly little academic literature …

Moore’S Law, Metcalfe’S Law, And The Theory Of Optimal Interoperability, Christopher S. Yoo

All Faculty Scholarship

Many observers attribute the Internet’s success to two principles: Moore’s Law and Metcalfe’s Law. These precepts are often cited to support claims that larger networks are inevitably more valuable and that costs in a digital environment always decrease. This Article offers both a systematic description of both laws and then challenges the conventional wisdom by exploring their conceptual limitations. It also explores how alternative mechanisms, such as gateways and competition, can permit the realization benefits typically attributed to Moore’s Law and Metcalfe’s Law without requiring increases in network size.

U.S. Vs. European Broadband Deployment: What Do The Data Say?, Christopher S. Yoo

All Faculty Scholarship

As the Internet becomes more important to the everyday lives of people around the world, commentators have tried to identify the best policies increasing the deployment and adoption of high-speed broadband technologies. Some claim that the European model of service-based competition, induced by telephone-style regulation, has outperformed the facilities-based competition underlying the US approach to promoting broadband deployment. The mapping studies conducted by the US and the EU for 2011 and 2012 reveal that the US led the EU in many broadband metrics.

• High-Speed Access: A far greater percentage of US households had access to Next Generation Access (NGA) …

Technological Determinism And Its Discontents, Christopher S. Yoo

All Faculty Scholarship

This book review takes a critical review of the claim advanced by Susan Crawford in Captive Audience that the merger between Comcast and NBC Universal would harm consumers and that policymakers should instead promote common carriage regulation and subsidize municipal symmetrical gigabit fiber-to-the-home (FTTH). First it evaluates the extent to which next-generation digital subscriber lines (DSL) and wireless broadband technologies can serve as effective substitutes for cable modem service, identifying FCC data showing that the market has become increasingly competitive and likely to continue to do so. Furthermore, the market is not structured in a way that would permit the …

A Brief Overview Of The Nebula Future Internet Architecture, Tom Anderson, Ken Birman, Robert Broberg, Matthew Caesar, Douglas Comer, Chase Cotton, Michael J. Freedman, Andreas Haeberlen, Zachary G. Ives, Arvind Krishnamurthy, William Lehr, Boon Thau Loo, David Mazieres, Antonio Nicolosi, Jonathan M. Smith, Ion Stoica, Robbert Van Renesse, Michael Walfish, Hakim Weatherspoon, Christopher S. Yoo

All Faculty Scholarship

NEBULA is a proposal for a Future Internet Architecture. It is based on the assumptions that: (1) cloud computing will comprise an increasing fraction of the application workload offered to an Internet, and (2) that access to cloud computing resources will demand new architectural features from a network. Features that we have identified include dependability, security, flexibility and extensibility, the entirety of which constitute resilience.

NEBULA provides resilient networking services using ultrareliable routers, an extensible control plane and use of multiple paths upon which arbitrary policies may be enforced. We report on a prototype system, Zodiac, that incorporates these latter …

Possible Paradigm Shifts In Broadband Policy, Christopher S. Yoo

All Faculty Scholarship

Debates over Internet policy tend to be framed by the way the Internet existed in the mid-1990s, when the Internet first became a mass-market phenomenon. At the risk of oversimplifying, the Internet was initially used by academics and tech-savvy early adopters to send email and browse the web over a personal computer connected to a telephone line via networks interconnected through in a limited way. Since then, the Internet has become much larger and more diverse in terms of users, applications, technologies, and business relationships. More recently, Internet growth has begun to slow both in terms of the number of …

Toward A Closer Integration Of Law And Computer Science, Christopher S. Yoo

All Faculty Scholarship

Legal issues increasingly arise in increasingly complex technological contexts. Prominent recent examples include the Stop Online Piracy Act (SOPA) and the Protect Intellectual Property Act (PIPA), network neutrality, the increasing availability of location information, and the NSA’s surveillance program. Other emerging issues include data privacy, online video distribution, patent policy, and spectrum policy. In short, the rapid rate of technological change has increasingly shown that law and engineering can no longer remain compartmentalized into separate spheres. The logical response would be to embed the interaction between law and policy deeper into the fabric of both fields. An essential step would …

The Taxation Of Cloud Computing And Digital Content, David Shakow

All Faculty Scholarship

“Cloud computing” raises important and difficult questions in state tax law, and for Federal taxes, particularly in the foreign tax area. As cloud computing solutions are adopted by businesses, items we view as tangible are transformed into digital products. In this article, I will describe the problems cloud computing poses for tax systems. I will show how current law is applied to cloud computing and will identify the difficulties current approaches face as they are applied to this developing technology.

My primary interest is how Federal tax law applies to cloud computing, particularly as the new technology affects international transactions. …

Competition In Information Technologies: Standards-Essential Patents, Non-Practicing Entities And Frand Bidding, Herbert J. Hovenkamp

All Faculty Scholarship

Standard Setting is omnipresent in networked information technologies. Virtually every cellular phone, computer, digital camera or similar device contains technologies governed by a collaboratively developed standard. If these technologies are to perform competitively, the processes by which standards are developed and implemented must be competitive. In this case attaining competitive results requires a mixture of antitrust and non-antitrust legal tools.

FRAND refers to a firm’s ex ante commitment to make its technology available at a “fair, reasonable and nondiscriminatory royalty.” The FRAND commitment results from bidding to have one’s own technology selected as a standard. Typically the FRAND commitment is …

The Law And Economics Of Liability Insurance: A Theoretical And Empirical Review, Tom Baker, Peter Siegelman

All Faculty Scholarship

We survey the theoretical and empirical literature on the law and economics of liability insurance. The canonical Shavell model predicts that, despite the presence of some ex ante moral hazard (care-reduction by insureds), liability insurance will generally raise welfare because its risk-spreading gains will likely be larger than its adverse effects on precautionary activities. We discuss the numerous features of liability insurance contracts that are designed to reduce ex ante moral hazard, and examine the evidence of their effects. Most studies conclude that these features work reasonably well, so that liability insurance probably does not generate substantial ex ante moral …

When Antitrust Met Facebook, Christopher S. Yoo

All Faculty Scholarship

Social networks are among the hottest phenomena on the Internet. Facebook eclipsed Google as the most visited website in both 2010 and 2011. Moreover, according to Nielsen estimates, as of the end of 2011 the average American spent nearly seven hours per month on Facebook, which is more time than they spent on Google, Yahoo!, YouTube, Microsoft, and Wikipedia combined. LinkedIn’s May 19, 2011 initial public offering (“IPO”) surpassed expectations, placing the value of the company at nearly $9 billion, and approximately a year later, its stock price had risen another 20 percent. Facebook followed suit a year later with …

Beyond Coase: Emerging Technologies And Property Theory, Christopher S. Yoo

All Faculty Scholarship

In addition to prompting the development of the Coase Theorem, Ronald Coase’s landmark 1959 article on the Federal Communications Commission touched off a revolution in spectrum policy. Although one of Coase’s proposed reforms (that spectrum should be allocated through markets) has now become the conventional wisdom, his other principal recommendation (that governments stop dedicating portions of the spectrum to particular uses) has yet to be fully embraced. Drawing on spectrum as well as Internet traffic and electric power as examples, this Article argues that emerging technologies often reflect qualities that make defining property rights particularly difficult. These include the cumulative …

Network Neutrality And The Need For A Technological Turn In Internet Scholarship, Christopher S. Yoo

All Faculty Scholarship

To most social scientists, the technical details of how the Internet actually works remain arcane and inaccessible. At the same time, convergence is forcing scholars to grapple with how to apply regulatory regimes developed for traditional media to a world in which all services are provided via an Internet-based platform. This chapter explores the problems caused by the lack of familiarity with the underlying technology, using as its focus the network neutrality debate that has dominated Internet policy for the past several years. The analysis underscores a surprising lack of sophistication in the current debate. Unfamiliarity with the Internet’s architecture …

Cloud Computing: Architectural And Policy Implications, Christopher S. Yoo

All Faculty Scholarship

Cloud computing has emerged as perhaps the hottest development in information technology. Despite all of the attention that it has garnered, existing analyses focus almost exclusively on the issues that surround data privacy without exploring cloud computing’s architectural and policy implications. This article offers an initial exploratory analysis in that direction. It begins by introducing key cloud computing concepts, such as service-oriented architectures, thin clients, and virtualization, and discusses the leading delivery models and deployment strategies that are being pursued by cloud computing providers. It next analyzes the economics of cloud computing in terms of reducing costs, transforming capital expenditures …

Rough Consensus And Running Code: Integrating Engineering Principles Into Internet Policy Debates, Christopher S. Yoo

All Faculty Scholarship

This is the introduction to a symposium issue for a conference designed to bring the engineering community, policymakers, legal academics, and industry participants together in an attempt to provide policymakers with a better understanding of the Internet’s technical aspects and to explore emerging issues of particular importance to current broadband policy.

The Shifting Terrain Of Risk And Uncertainty On The Liability Insurance Field, Tom Baker

All Faculty Scholarship

Recent sociological and historical work suggests that insurance risks often are not reliably calculable, except in hindsight. Insurance is “an uncertain business,” characterized by competition for premiums that pushes insurers into the unknown. This essay takes some preliminary steps that extend this insight into the liability insurance field. The essay first provides a simple quantitative comparison of U.S. property and liability insurance premiums over the last sixty years, setting the stage to make three points: (1) liability insurance premiums have grown at a similar rate as property insurance premiums and GDP over this period, providing yet another piece of evidence …

The Best Available Technology Standard, Lital Helman, Gideon Parchomovsky

All Faculty Scholarship

Copyright liability for web-hosting will be a key determinant of the evolution of the Internet in years to come. Depending on their design, the legal rules that shape the liability of web-hosts can stunt the development of the Internet as a medium of expression or enhance it. Hence, adopting the optimal liability regime is a matter of crucial importance. This Article proposes a radical change in web-hosts’ copyright liability for illegal content posted by users. Our main thesis is that web-hosts’ liability should be guided by the “Best Available Technology” principle, according to which web-hosts that employ the best filtering …

Product Life Cycle Theory And The Maturation Of The Internet, Christopher S. Yoo

All Faculty Scholarship

Much of the recent debate over Internet policy has focused on the permissibility of business practices that are becoming increasingly common, such as new forms of network management, prioritization, pricing, and strategic partnerships. This Essay analyzes these developments through the lens of the management literature on the product life cycle, dominant designs, technological trajectories and design hierarchies, and the role of complementary assets in determining industry structure. This analysis suggests that many of these business practices may represent nothing more than a reflection of how the nature of competition changes as industries mature. This in turn suggests that network neutrality …

Is The Internet A Maturing Market? If So, What Does That Imply?, Christopher S. Yoo

All Faculty Scholarship

Network providers are experimenting with a variety of new business arrangements. Some are offering specialized services the guarantee higher levels of quality of service those willing to pay for it. Others are entering into strategic partnerships that allocate more bandwidth to certain sources. Interestingly, a management literature exists suggesting that both developments may simply reflect the ways that the nature of competition and innovation can be expected as markets mature. The real question is not if the nature of competition and innovation will change, but rather when and how. This theory also suggests that policymakers should be careful not to …

Global Warming Advocacy Science: A Cross Examination, Jason S. Johnston

All Faculty Scholarship

Legal scholarship has come to accept as true the various pronouncements of the Intergovernmental Panel on Climate Change (IPCC) and other scientists who have been active in the movement for greenhouse gas (ghg) emission reductions to combat global warming. The only criticism that legal scholars have had of the story told by this group of activist scientists – what may be called the climate establishment – is that it is too conservative in not paying enough attention to possible catastrophic harm from potentially very high temperature increases. This paper departs from such faith in the climate establishment by comparing the …

Network Neutrality Or Internet Innovation?, Christopher S. Yoo

All Faculty Scholarship

Over the past two decades, the Internet has undergone an extensive re-ordering of its topology that has resulted in increased variation in the price and quality of its services. Innovations such as private peering, multihoming, secondary peering, server farms, and content delivery networks have caused the Internet’s traditionally hierarchical architecture to be replaced by one that is more heterogeneous. Relatedly, network providers have begun to employ an increasingly varied array of business arrangements and pricing. This variation has been interpreted by some as network providers attempting to promote their self interest at the expense of the public. In fact, these …

Innovations In The Internet’S Architecture That Challenge The Status Quo, Christopher S. Yoo

All Faculty Scholarship

The current debate over broadband policy has largely overlooked a number of changes to the architecture of the Internet that have caused the price paid by and quality of service received by traffic traveling across the Internet to vary widely. Topological innovations, such as private peering, multihoming, secondary peering, server farms, and content delivery networks, have caused the Internet’s traditionally hierarchical architecture to be replaced by one that is more heterogeneous. Moreover, network providers have begun to employ an increasingly varied array of business arrangements. Some of these innovations are responses to the growing importance of peer-to-peer technologies. Others, such …

Assuming The Risk: Tort Law, Policy, And Politics On The Slippery Slopes, Eric Feldman, Alison I. Stein

All Faculty Scholarship

Prominent jurists and legal scholars have long been critical of the doctrine of the assumption of risk, arguing that it is logically flawed and has sown confusion in the courts. This article takes a fresh look at the assumption of risk by focusing on legal conflicts over ski accidents in three ski-intensive states—Vermont, Colorado, and California. It argues that the tort doctrine of the assumption of risk remains vital, and highlights the way in which powerful political and economic actors with links to the ski industry have lobbied aggressively for state laws that codify the assumption of risk. The result …

The Changing Patterns Of Internet Usage, Christopher S. Yoo

All Faculty Scholarship

The Internet unquestionably represents one of the most important technological developments in recent history. It has revolutionized the way people communicate with one another and obtain information and created an unimaginable variety of commercial and leisure activities. Interestingly, many members of the engineering community often observe that the current network is ill-suited to handle the demands that end users are placing on it. Indeed, engineering researchers often describe the network as ossified and impervious to significant architectural change. As a result, both the U.S. and the European Commission are sponsoring “clean slate” projects to study how the Internet might be …

The Convergence Of Broadcasting And Telephony: Legal And Regulatory Implications, Christopher S. Yoo

All Faculty Scholarship

This article, written for the inaugural issue of a new journal, analyzes the extent to which the convergence of broadcasting and telephony induced by the digitization of communications technologies is forcing policymakers to rethink their basic approach to regulating these industries. Now that voice and video are becoming available through every transmission technology, policymakers can no longer define the scope of regulatory obligations in terms of the mode of transmission. In addition, jurisdictions that employ separate agencies to regulate broadcasting and telephony must reform their institutional structures to bring both within the ambit of a single regulatory agency. The emergence …
