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.

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

Faculty Scholarship at Penn Law

Since June 2012, mobile wireless has emerged as the largest and fast growing medium for broadband service. At the same time, mobile wireless networks have proven considerably more difficult to manage than wireline networks. The primary causes are the rapid growth in demand for wireless bandwidth and the greater susceptibility of wireless networks to poor quality of service because of the omnidirectional propagation of wireless signals, bad handoffs, local congestion, and the susceptibility to complex interference patterns caused by multipath propagation. Moreover, the central inference underlying the primary form of congestion management is not valid for wireless networks. As a ...
