Cloud Computing, Contractibility, And Network Architecture, Christopher S. Yoo
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.
Cloud Computing: Architectural And Policy Implications, Christopher S. Yoo
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 …
The Changing Patterns Of Internet Usage, Christopher S. Yoo
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
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 …
Network Neutrality After Comcast: Toward A Case-By-Case Approach To Reasonable Network Management, Christopher S. Yoo
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 …
