Resource utilisation (FRU)

This class provides three families that support the availability of required resources such as processing capability and/or storage capacity. The family Fault Tolerance provides protection against unavailability of capabilities caused by failure of the TOE. The family Priority of Service ensures that the resources will be allocated to the more important or time-critical tasks, and cannot be monopolised by lower priority tasks. The family Resource Allocation provides limits on the use of available resources, therefore preventing users from monopolising the resources.
