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

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

Faculty Scholarship at Penn Law

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.


Moore’S Law, Metcalfe’S Law, And The Theory Of Optimal Interoperability, Christopher S. Yoo Jan 2015

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

Faculty Scholarship at Penn Law

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.
