On Quality of Service Optimization With Discrete QoS Options

Quality of Service (QoS) control is considered an important user demand and therefore receives wide attention, especially in the areas of computer networks and real-time multimedia systems. This paper presents a QoS management scheme that enables people to quantitatively measure QoS, and to analytically plan and allocate resource. In this model, available system resources are apportioned across multiple applications such that the net utility that accrues to the end-users of those applications is maximized. The author primarily works with "Continuous" QoS dimensions, and assumed that the 'Utility' gained by improvements along a QoS dimension were always representable by concave functions.
