Abstract: This study focus on regulating the throughput of a request to the service class to achieve differentiated Quality of Service (QoS). Assume, all incoming requests are higher priority in differentiated service then its performance degrades. In order to avoid such things, Dynamic Prioritization Middleware (DPM) is proposed. Throughput is the mixture of requests. Throughput of requests is controlled using penalty function present in the scheduler. Managed QoS policies encode both static and dynamic scheduling.
