"Adaptive Quality of Service Architecture"
(for the Linux kernel)


The IRMOS European Project

The IRMOS (Interactive Real-Time Multimedia Applications on Service-Oriented Infrastructures) FP7 European Project aims to enable "Real-time" interaction between people and applications over a Service Oriented Infrastructure, where processing, storage and networking needs to be combined and delivered with guaranteed levels of service. The AQuoSA architecture has been used often for the experimental validation of the research activities performed within the project. Also, there is a plan for integrating into AQuoSA the new hierarchical EDF/FP real-time scheduler developed within IRMOS.


AQuoSA may be used as CPU Resource Manager within the FRSH-FORB middleware implementing the FRESCOR API for real-time scheduling on the Linux OS.

The FRESCOR European Project

Development of some of the AQuoSA components is being partially supported by the FRESCOR European project (Framework for Real-time Embedded Systems based on COntRacts).

The OCERA Project

The base resource reservation module was initially developed inside the OCERA European project (Open Components for Embedded Real-time Applications).

The RETIS Laboratory at Scuola Superiore Sant'Anna

The AQuoSA project constitutes an essential testbed for experimenting with results of the research made by the Real Time System Laboratory of Scuola Superiore Sant'Anna (Pisa, Italy) in the field of Quality of Service control in soft real-time systems.

The ICT Department at University of Trento

The ICT Department of University of Trento (Trento, Italy), is actively contributing to the project, by both using AQuoSA for educational purposes, and by providing additional software components at the application level. Also, a joint research area with RETIS at Scuola Superiore Sant'Anna aims at continuously experimenting with the latest and newest in-kernel scheduling-related mechanisms, so to keep the AQuoSA core components up to date with the maximum potentiality of the latest Linux kernel and available patches.
