DeSiDeRaTa: QoS Management Technology for Dynamic, Scalable, Dependable, Real-Time Systems

摘要

The DeSiDeRaTa project is producing technology to enable the engineering of the emerging generation of distributed real-time systems. Such systems have rigorous Quality of Service (QoS) objectives. They must behave in a dependable manner, respond to threats in a timely fashion and provide continuous availability, even within hostile and unknown environments. To provide the desired QoS in such a context, the DeSiDeRaTa project focuses on QoS specification, dynamic QoS management middleware, and benchmarking of dynamic real-time systems. This paper discusses each of these aspects and presents experimental results of applying DeSiDeRaTa technology to a dynamic real-time benchmark system.
