Abstract :
This paper extends previous QoS contract and proposes a QoS notification mechanism. With these methods, QoS requirements of applications in DRE systems can be satisfied dynamically. Contract specifies different levels of QoS needs for multiple tasks and QoS notification allows client to change its QoS requirement according to the external conditions. QuO can also adjust QoS levels of running tasks to achieve the best system performance.
