Abstract

The resource-sharing problem in priority-driven real-timesystems has been studied at length, with the resultthat some effective and practical solutions are available forboth fixed-priority and dynamic-priority systems. In recentyears, real-time operating systems have begun to supportthe resource reservation paradigm, providing a "temporalisolation" abstraction.However, the problem of sharinglogical resources across reserved applications has not beenextensively studied. In this paper, we consider both the theoretical and practical implications of such resource-sharingin reservation-based systems. Moreover, we provide someexperimental results from the implementation of our pro-posedschemes in Linux/RK, a "resource kernel" that sup-portsreservations.
