    Abstract

    The Performability Manager (PM) is a distributed system component which maintains the application-requested Quality of Service (QoS) by dynamically reconfiguring ANSAware-based distributed applications, using a model-based optimization procedure. The PM receives information about the ANSAware-based application from a distributed monitoring process based on JEWEL and DEMON. With this information, and using predefined stochastic Petri net (SPN) models of ANSAware applications, the PM automatically constructs an overall SPN performability model which is subsequently used for the determination of the provided QoS. Based on the analysis results, the PM can decide to initiate on-line system reconfigurations, if such is needed for maintaining the requested QoS. ANSAware provides facilities for these dynamic reconfigurations.

    In this paper we focus on the modelling aspects of model-based dynamic QoS management by the performability manager. We present an ANSAware-based experimental distributed environment in which the modelling and evaluation aspects are totally automated. We also show the feasibility of the proposed PM by presenting some operational results.
