Abstract

Assuring quality of service (QoS) requirements is critical when assembling a distributed real-time and embedded (DRE) system from a repository of existing software and hardware components. This paper presents a two-level approach for assuring satisfaction of QoS requirements in the context of a reduced design space for DRE systems. Techniques from artificial intelligence and statistics are used to fulfill these collective objectives at system assembly time. The result not only lessens the overhead of validation of QoS requirements at run-time, but also reduces the development and integration cost of DRE systems.
