Quality-of-Service Directed Targeting Based on the ODP Engineering Model
Georg Ræder, Shahrzade Mazaher · 1995
When developing large distributed systems, the final transformation steps toward executable components (targeting) are usually complex and platform dependent. The ODP Engineering Model provides a framework for alleviating this situation, but methods and tools that realize its potential are still lacking. This paper gives an example of a distribution configuration language and shows how it can be used, together with SDL, to achieve platform-independent distributed targeting. Furthermore, targeting decisions should be made on the basis of quality-of-service constraints, such as performance and reliability requirements, and the paper shows how our language can serve as a basis for stating and checking such constraints. Finally, the relation of our work to dynamic reconfiguration is discussed.
