A unified framework for managing different resources with QoS guarantees

This paper describes ongoing research activities aimed at developing a unified framework by which a general purpose operative system is able to support applications with Quality of Service requirements. The work is focused on a feedback based dynamic management of the resources required by an application, where each resource is handled through the use of a Resource Reservation paradigm. This allows applications to share the access to a resource by specifying the fraction of usage, where such fractions are dynamically adapted by the system on the basis of observations made on the hosted activities.
