Response-time control of a single server queue

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 investigate a feedback-based prediction scheme for controlling a single server queue. This control structure has the benefit over other previously suggested control structures that no measurement of the required work of each job is needed. However, our solution maintains the same attractive properties, regarding average response time and variance.
