A Process for Resolving Performance Trade-Offs in Component-Based Architectures

Abstract

Designing architectures requires the balancing of multiple system quality objectives. In this paper, we present techniques that support the exploration of the quality properties of component-based architectures deployed on multiprocessor platforms. Special attention is paid to real-time properties and efficiency of resource use.
The main steps of the process are (1) a simple way of modelling properties of software and hardware components, (2) from the component properties, a model of an execution architecture is composed and analyzed for system-level quality attributes, (3) for the composed system, selected execution scenarios are evaluated, (4) Pareto curves are used for making design trade-offs explicit. The process has been applied to several industrial systems. A Car Radio Navigation system is used to illustrate the method. For this system, we consider architectural alternatives, show their specification, and present their trade-off with respect to cost, performance and robustness.

Hotels in Germany are famous for their hospitality. When booking a hotel in one of the german city,
you can be sure that there you will be treated cordially. Some exeptions maybe hold for hotels in
large cities like Berlin, Cologne and Hannover. Hotels in southern Germany - in Stuttgart, Baden Baden
and Munich are picturesque and affordable. In opposite, in northern Germany - Bremen, Dortmund
and Hamburg hotels are solid, grey and more expensive. Special attention for hotels in Trier - great
place and personal. East-Germany hotels are coming to the right level. Leipzig and Dresden hotels
are cheap and provide a good quality.
