What Is The Relationship Between Language And Thought?: Linguistic Relativity And Its Implications For Copyright, Christopher S. Yoo

All Faculty Scholarship

To date, copyright scholarship has almost completely overlooked the linguistics and cognitive psychology literature exploring the connection between language and thought. An exploration of the two major strains of this literature, known as universal grammar (associated with Noam Chomsky) and linguistic relativity (centered around the Sapir-Whorf hypothesis), offers insights into the copyrightability of constructed languages and of the type of software packages at issue in Google v. Oracle recently decided by the Supreme Court. It turns to modularity theory as the key idea unifying the analysis of both languages and software in ways that suggest that the information filtering associated …

Lowering Legal Barriers To Rpki Adoption, Christopher S. Yoo, David A. Wishnick

All Faculty Scholarship

Across the Internet, mistaken and malicious routing announcements impose significant costs on users and network operators. To make routing announcements more reliable and secure, Internet coordination bodies have encouraged network operators to adopt the Resource Public Key Infrastructure (“RPKI”) framework. Despite this encouragement, RPKI’s adoption rates are low, especially in North America.

This report presents the results of a year-long investigation into the hypothesis—widespread within the network operator community—that legal issues pose barriers to RPKI adoption and are one cause of the disparities between North America and other regions of the world. On the basis of interviews and analysis of …

Common Carriage’S Domain, Christopher S. Yoo

All Faculty Scholarship

The judicial decision invalidating the Federal Communications Commission's first Open Internet Order has led advocates to embrace common carriage as the legal basis for network neutrality. In so doing, network neutrality proponents have overlooked the academic literature on common carriage as well as lessons from its implementation history. This Essay distills these learnings into five factors that play a key role in promoting common carriage's success: (1) commodity products, (2) simple interfaces, (3) stability and uniformity in the transmission technology, (4) full deployment of the transmission network, and (5) stable demand and market shares. Applying this framework to the Internet …

An Unsung Success Story: A Forty-Year Retrospective On U.S. Communications Policy, Christopher S. Yoo

All Faculty Scholarship

Looking backwards on the occasion of Telecommunications Policy’s fortieth anniversary reveals just how far U.S. communications policy has come. All of the major challenges of 1976, such as promoting competition in customer premises equipment, long distance, and television networking, have largely been overcome. Moreover, new issues that emerged later, such as competition in local telephone service and multichannel video program distribution, have also largely been solved. More often than not, the solution has been the result of structural changes that enhanced facilities-based competition rather than agency-imposed behavioral requirements. Moreover, close inspection reveals that in most cases, prodding by the courts …

Modularity Theory And Internet Regulation, Christopher S. Yoo

All Faculty Scholarship

Modularity is often cited as one of the foundations for the Internet’s success. Unfortunately, academic discussions about modularity appearing in the literature on Internet policy are undertheorized. The persistence of nonmodular architectures for some technologies underscores the need for some theoretical basis for determining when modularity is the preferred approach. Even when modularity is desirable, theory must provide some basis for making key design decisions, such as the number of modules, the location of the interfaces between the modules, and the information included in those interfaces.

The literature on innovation indicates that modules should be determined by the nature of …

Wireless Network Neutrality: Technological Challenges And Policy Implications, Christopher S. Yoo

All Faculty Scholarship

One key aspect of the debate over network neutrality has been whether and how network neutrality should apply to wireless networks. The existing commentary has focused on the economics of wireless network neutrality, but to date a detailed analysis of how the technical aspects of wireless networks affect the implementation of network neutrality has yet to appear in the literature. As an initial matter, bad handoffs, local congestion, and the physics of wave propagation make wireless broadband networks significantly less reliable than fixed broadband networks. These technical differences require the network to manage dropped packets and congestion in a way …

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 …

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 …

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 …

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 …

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 …

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 …

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 …

Network Neutrality After Comcast: Toward A Case-By-Case Approach To Reasonable Network Management, Christopher S. Yoo

All Faculty Scholarship

The Federal Communications Commission’s recent Comcast decision has rejected categorical, ex ante restrictions on Internet providers’ ability to manage their networks in favor of a more flexible approach that examines each dispute on a case-by-case basis, as I have long advocated. This book chapter, written for a conference held in February 2009, discusses the considerations that a case-by-case approach should take into account. First, allowing the network to evolve will promote innovation by allowing the emergence of applications that depend on a fundamentally different network architecture. Indeed, as the universe of Internet users and applications becomes more heterogeneous, it is …

Network Neutrality, Consumers, And Innovation, Christopher S. Yoo

All Faculty Scholarship

In this Article, Professor Christopher Yoo directly engages claims that mandating network neutrality is essential to protect consumers and to promote innovation on the Internet. It begins by analyzing the forces that are placing pressure on the basic network architecture to evolve, such as the emergence of Internet video and peer-to-peer architectures and the increasing heterogeneity in business relationships and transmission technologies. It then draws on the insights of demand-side price discrimination (such as Ramsey pricing) and the two-sided markets, as well as the economics of product differentiation and congestion, to show how deviating from network neutrality can benefit consumers, …

Rethinking Broadband Internet Access, Daniel F. Spulber, Christopher S. Yoo

All Faculty Scholarship

The emergence of broadband Internet technologies, such as cable modem and digital subscriber line (DSL) systems, has reopened debates over how the Internet should be regulated. Advocates of network neutrality and open access to cable modem systems have proposed extending the regulatory regime developed to govern conventional telephone and narrowband Internet service to broadband. A critical analysis of the rationales traditionally invoked to justify the regulation of telecommunications networks--such as natural monopoly, network economic effects, vertical exclusion, and the dangers of ruinous competition--reveals that those rationales depend on empirical and theoretical preconditions that do not apply to broadband. In addition, …

What Can Antitrust Contribute To The Network Neutrality Debate?, Christopher S. Yoo

All Faculty Scholarship

Over the course of the last year, policymakers have begun to consider whether antitrust can play a constructive role in the network neutrality debate. A review of both the theory and the practice of antitrust suggests that it does have something to contribute. As an initial matter, antitrust underscores that standardization and interoperability are not always beneficial and provides a framework for determining the optimal level of standardization. In addition, the economic literature and legal doctrine on vertical exclusion reveal how compelling network neutrality could reduce static efficiency and show how mandating network neutrality could impair dynamic efficiency by deterring …

Keeping The Internet Neutral?: Tim Wu And Christopher Yoo Debate, Tim Wu, Christopher S. Yoo

All Faculty Scholarship

"Net neutrality" has been among the leading issues of telecommunications policy this decade. Is the neutrality of the Internet fundamental to its success, and worth regulating to protect, or simply a technical design subject to improvement? In this debate-form commentary, Tim Wu and Christopher Yoo make clear the connection between net neutrality and broader issues of national telecommunications policy.

Mandating Access To Telecom And The Internet: The Hidden Side Of Trinko, Daniel F. Spulber, Christopher S. Yoo

All Faculty Scholarship

Antitrust has long played a major role in telecommunications policy, demonstrated most dramatically by the equal access mandate imposed during the breakup of AT&T. In this Article we explore the extent to which antitrust can continue to serve as a source of access mandates following the Supreme Court's 2004 Trinko decision. Although Trinko sharply criticized access remedies and antitrust courts' ability to enforce them, it is not yet clear whether future courts will interpret the opinion as barring all antitrust access claims. Even more importantly, the opinion contains language hinting at possible bases for differentiating among different types of access, …
