A dynamic QoS control based on optimistic processor reservation

Abstract

The paper proposes a dynamic QOS control scheme using a processor reservation system. In our scheme, a system allocates processor capacity for each application, then the application increases or decreases the current resource usage by using a feedback mechanism. This scheme allows the application to reserve resources optimistically. This means that a system can allocate all processor resources to respective applications every time. Our approach makes it easy to build a continuous media application with a dynamic QOS control scheme, and allocates processor capacity very efficiently without unexpected degradation of a media stream's quality.
