Network Neutrality Or Internet Innovation?, Christopher S. Yoo Apr 2010

Network Neutrality Or Internet Innovation?, Christopher S. Yoo

Faculty Scholarship at Penn Law

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 ...


Innovations In The Internet’S Architecture That Challenge The Status Quo, Christopher S. Yoo Jan 2010

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

Faculty Scholarship at Penn Law

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 ...


Network Neutrality After Comcast: Toward A Case-By-Case Approach To Reasonable Network Management, Christopher S. Yoo Feb 2009

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

Faculty Scholarship at Penn Law

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 ...


Network Neutrality, Consumers, And Innovation, Christopher S. Yoo Aug 2008

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

Faculty Scholarship at Penn Law

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 ...
