An Approach for Quality of Service Management
Chen Lee, Daniel P. Siewiorek · 1998
We present a translucent QoS management optimization framework for systems that must satisfy application needs along multiple dimensions such as timeliness, reliability, cryptographic security and other application-specific quality requirements. The architecture of the system consists of a semantically rich (in terms of customizable and expressiveness) QoS specification interface for multidimensional QoS provisioning, a quality-of-service index model to help the user make the quality trade-o# decision, and a unified QoS-based admission control and resource planning system.The semantically rich QoS specification interface allows the user or system administrator to define fine-grained service requests in terms of quality or rate of service. The QoS index model is designed to be flexible and policy driven. The unified QoS-based admission and resource control facilitates the deployment of various QoS policies to meet performance objectives for specific service optimizations. Finally, the ov...
