An Unsung Success Story: A Forty-Year Retrospective On U.S. Communications Policy, Christopher S. Yoo Nov 2017

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 …


Open Source, Modular Platforms, And The Challenge Of Fragmentation, Christopher S. Yoo Nov 2016

Open Source, Modular Platforms, And The Challenge Of Fragmentation, Christopher S. Yoo

All Faculty Scholarship

Open source and modular platforms represent two powerful conceptual paradigms that have fundamentally transformed the software industry. While generally regarded complementary, the freedom inherent in open source rests in uneasy tension with the strict structural requirements required by modularity theory. In particular, third party providers can produce noncompliant components, and excessive experimentation can fragment the platform in ways that reduce its economic benefits for end users and app providers and force app providers to spend resources customizing their code for each variant. The classic solutions to these problems are to rely on some form of testing to ensure that the …


Cloud Computing, Contractibility, And Network Architecture, Christopher S. Yoo Apr 2015

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.


Rough Consensus And Running Code: Integrating Engineering Principles Into Internet Policy Debates, Christopher S. Yoo Mar 2011

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 Convergence Of Broadcasting And Telephony: Legal And Regulatory Implications, Christopher S. Yoo Dec 2009

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 …


Architectural Censorship And The Fcc, Christopher S. Yoo Jan 2005

Architectural Censorship And The Fcc, Christopher S. Yoo

All Faculty Scholarship

Most First Amendment analyses of U.S. media policy have focused predominantly on “behavioral” regulation, which either prohibits the transmission of disfavored content (such as indecent programming) or mandates the dissemination of preferred content (such as children’s educational programming and political speech). In so doing, commentators have largely overlooked how program content is also affected by “structural” regulation, which focuses primarily on increasing the economic competitiveness of media industries. In this Article, Professor Christopher Yoo employs economic analysis to demonstrate how structural regulation can constitute a form of “architectural censorship” that has the unintended consequence of reducing the quantity, quality, and …
