This paper describes a technique to enable live migration of virtual machines over the Internet. The method assumes the network supports Mobile IPv6 and that participating host devices support Xen 3.1. Unlike live migration schemes proposed by other researchers, virtual networks are not required. We describe our work in progress on developing a system that(More)
In this paper, we describe the principles, outlines, and implementation of a new undergraduate database course using MeTube (a variation of the well known YouTube) as a motivational semester-long project, which is attractive, fosters creativity in students and is complex enough to introduce DBMS theories and techniques. We provide detailed course assessment(More)
Two new shadow generation techniques are introduced to produce realistic, perceptually correct soft shadows. Penumbra volume mapping and penumbra volume mask filtering exploit modern programmable graphics hardware and are able to shadow dynamic scenes at real-time rates. Penumbra volumes extend previous sampling based approaches by masking regions where(More)
The number of households and businesses using HFC cable networks for Internet access is rapidly model of the DOCSIS MAC using the 'ns' simulation package. In this paper we provide analytic and live network evidence that the simulation model is correct. To demonstrate the model, we provide the results of a brief simulation-based performance evaluation(More)
