Abstract :
The use of admission control and overload management techniques in real-time systems has been shown to result in improved system performance-in terms of maximizing the value-added to the system by those transactions committing on time-in comparison to systems which do not employ such techniques. Continuing with our research in hard deadline Real-Time DataBase (RTDB) systems, we investigate the challenges associated with soft deadline transactions and describe a number of admission control and overload management techniques as well as scheduling algorithms appropriate for such systems
