Optimal Design for Reservation Servers under Shared Resources

Modularity and hierarchical-based design are crucial features that need to be supported in complex embedded systems characterized by multiple applications with timing requirements.Resource reservation is a powerful scheduling mechanism for achieving such goals and providing temporal isolation among different real-time applications. When different applications share mutually exclusive resources, a precise feasibility analysis can still be performed in isolation, using specific resource access protocols, taking into account only the application features and the reservation parameters. This paper presents a methodology for selecting the parameters of each reservation in order to guarantee the feasibility of the served applications and minimize the required bandwidth.
