Recent studies take two different approaches to admission control.Some argue that due scalability limitations, using a signaling protocol to setup reservations is too costly and CPU-intensive for routers. Instead, endusers should apply various end-to-end measurement-based mechanisms to...

Design of Next Step In Signaling (NSIS) protocol and IP routing interaction requires a good understanding of today's Internet routing behavior. In this report we present a routing measurement experiment to characterize current Internet dynamics, including routing pathology, routing prevalence...

The internet has become a critical communications infrastructure, and access is among the “assets, systems, and networks, whether physical or virtual, [that] are considered so vital to the United States that their incapacitation or destruction would have a debilitating effect on security,...

The on-line estimation of derivatives is of fundamental importance in gradient-based routing algorithm for data networks and other applications. Smoothed perturbation analysis as proposed in this paper requires minimal knowledge about the system statistics. It is shown that smoothed perturbation...

Conceived in an effort to improve clinical operations, patient experience, and medical quality, physician-owned hospitals (POHs) flourished until 2003, when industry concerns over patient selection, cost of care, and overutilization prompted government oversight and legislation. Subsequent...

To complement the existing literature on expanding access to high-quality college education, we investigate the understudied topic of university outreach. Using a field experiment at West Point, we estimate the effectiveness of four university admissions outreach efforts (admissions office phone...
