Response-Time Control of a Processor-Sharing System Using Virtualized Server Environments

In English Feedback in server systems has during last years gained much interest in order to
fulfill still increasing demands on performance and optimization regarding, for example, quality
of service (QoS) requirements. In this paper we expand a previously published feedback–based
prediction scheme for controlling a single server queue together with a new control strategy.
These control structures have the benefit over other previously suggested control structures
that no off–line estimation of the required work is needed. In addition, our solutions maintain or
improve the performance, regarding average response time and loss of computational resources.
