Resource sharing in reservation-based systems

In recent years, real-time operating systems have begun to support the resource reservation paradigm. This technique has proved to be very effective in providing QoS to both, real-time and legacy applications, ensuring that the temporal misbehavior of an application does not affect any other. However, resource sharing in a reservation system is still not well understood, and can break the temporal isolation property due to priority inversion. We address this problem, presenting some solution strategies that can be considered extensions to priority inheritance and priority ceiling protocol emulation for reservation systems.
