document: A self-adjusting quality of service control scheme We propose and analyze a self-adjusting Quality of Service -LRB- QoS -RRB- control scheme with the goal of optimizing the system reward as a result of servicing different priority clients with varying workload , QoS and reward/penalty requirements . Our scheme is based on resource partitioning and designated `` degrade QoS areas '' such that system resources are partitioned into priority areas each of which is reserved specifically to serve only clients in a corresponding class with no QoS degradation , plus one `` degraded QoS area '' into which all clients can be admitted with QoS adjustment being applied only to the lowest priority clients . We show that the best partition is dictated by the workload and the reward/penalty characteristics of clients in difference priority classes . The analysis results can be used by a QoS manager to optimize the system total reward dynamically in response to changing workloads at run time . We demonstrate the validity of our scheme by means of simulation and comparing the proposed QoS self-adjusting scheme with those that do not use resource partitioning or designated degraded QoS areas
