Observation-Enhanced QoS Analysis of Component-Based Systems

Measurement-Based Characterization and Classification of QoS-Enhanced Systems

Quality-of-Service mechanisms and differentiated service classes are increasingly available in networks and Web servers. While network and Web server clients can assess their service by measuring basic performance parameters such as packet loss and delay, such measurements do not expose the system’s core QoS functionality such as multiclass service discipline. In this paper, we develop a framew...

QoS-Aware Dependency Management for Component-Based Systems

Hybrid multi-attribute QoS optimization in component based software systems

Design decisions for complex, component-based systems impact multiple quality of service (QoS) properties. Often, means to improve one quality property deteriorate another one. In this scenario, selecting a good solution with respect to a single quality attribute can lead to unacceptable results with respect to the other quality attributes. A promising way to deal with this problem is to exploi...

QoS analysis for component-based embedded software: Model and methodology

Component-based development (CBD) techniques have been widely used to enhance the productivity and reduce the cost for software systems development. However, applying CBD techniques to embedded software development faces additional challenges. For embedded systems, it is crucial to consider the quality of service (QoS) attributes, such as timeliness, memory limitations, output precision, and ba...

Behavioural analysis of component-based systems

Hardware Engineers have shown that building systems from components has brought enormous benefits. Using components permits hardware engineers to consider systems at an abstract level, making it possible for them to build and reason about systems that would otherwise be too large and complex to understand. It also enables them to make effective reuse of existing designs. It seems reasonable to ...
