Toward An Architecture Of A Component-Based System Supporting Separation Of Non- Functional Concerns

Jerzy Nogiec, Kelley Trombly-Freytag, Shangping Ren
2007 Zenodo  
The promises of component-based technology can only be fully realized when the system contains in its design a necessary level of separation of concerns.  ...  The authors propose to focus on the concerns that emerge throughout the life cycle of the system and use them as an architectural foundation for the design of a component-based framework.  ...  ACKNOWLEDGEMENTS The authors are grateful to all contributors to the EMS project for their efforts in implementing and shaping the framework.  ...

Automated Middleware QoS Configuration Techniques for Distributed Real-time and Embedded Systems

Amogh Kavimandan, Aniruddha Gokhale
2008 2008 IEEE Real-Time and Embedded Technology and Applications Symposium  
The paper evaluates the automation capabilities of GT-QMAP in the context of three DRE system case studies. The results indicate that on an average the modeling effort is reduced by over 75%.  ...  Quite often the modeling tools used in the development lifecycle of distributed real-time and embedded (DRE) systems are middleware-specific, where they elevate middleware artifacts, such as configuration  ...  Acknowledgement The authors would like to thank Reviewer 4 whose insightful and constructive comments and suggestions improved readibility and overall quality of the paper.  ...

Tool Support for Refinement of Non-functional Specifications

Simone Röttger, Steffen Zschaler
2006 Journal of Software and Systems Modeling  
Model driven architecture (MDA) views application development as a continuous transformation of models of the target system.  ...  We have also shown how this allows us to distinguish two roles in the development process: the measurement designer and the application designer.  ...  Acknowledgements We want to thank everybody in the COMQUAD project, Dr. Thomas Santen and the anonymous reviewers for their helpful comments on different versions of this paper.  ...

The Palladio component model for model-driven performance prediction

Steffen Becker, Heiko Koziolek, Ralf Reussner
2009 Journal of Systems and Software  
Our approach uses the Palladio Component Model (PCM) to specify component-based software architectures in a parametric way.  ...  Within a case study, we show that the resulting prediction accuracy is sufficient to support the evaluation of architectural design decisions.  ...  Acknowledgements: We thank all members of the Chair "Software Design and Quality" from the University of Karlsruhe for fruitful discussions and extensive proof-reading.  ...

A Framework for QoS Contract Negotiation in Component-Based Applications [chapter]

Mesfin Mulugeta, Alexander Schill
2008 Lecture Notes in Computer Science  
The framework can be integrated in a component container and act as a run-time support environment when QoS Contracts are negotiated under different application scenarios.  ...  The support of QoS properties in component-based software requires the run-time selection of appropriate concrete QoS contracts at the ports of the interacting components.  ...  We use the Comquad component model [5] that supports streams as special interface types and allows to specify nonfunctional properties for them.  ...

Formal specification of non-functional properties of component-based software systems

Steffen Zschaler
2009 Journal of Software and Systems Modeling  
They must be considered as early as possible in the development cycle in order to avoid costly failures. This is particularly true for a modern component-based approach to software development.  ...  The specification is modular and allows reasoning about properties of the composed system.  ...  This work was funded by the German Research Council as part of the COMQUAD project.  ...
