SHRUB: Shared Reclamation of Unused Bandwidth

is the task’s relative deadline.For a hard real-time task even a single deadline violation isconsidered as a severefault. In contrast, for a soft real-time task a few deadline violations are deemed accept-able provided that the anomaly is kept in check. In this case, reasonable QoS metricscan be are related to probability of missing a deadline, or to similar measurements.
