heavy traffic         regime, and derive closed form expressions to evaluate the relativefinite buffers for both   difference - in terms of average waiting times - of requests that belong   to different priority classes.   Our analysis allows to derive the expected waiting time of requests in single   server queueing systems, under the assumption of   non-preemptive and preemptive cases. Additionally, we extend our results to   a distributed scenario composed of an interconnected set of a large number   of unreliable single server queueing systems.   We then describe a number of applications and illustrate how to use our   theoretic foundation to analyze and tune their performance. The accuracy of   our analysis is validated through a set of experiments that we performed in a   synthetic setting.       In this work, we revisit the theory underlying a range of time-dependent   priority disciplines, and extend it to include the requirements of a class of   applications that has not been studied in the past. Specifically, we target applications   and services in which a scarce resource, or a fraction thereof, has   to be awarded to a large number of concurrent requests. We thus consider an
