A Self-Managing Wide-Area Data Streaming Service using Model-based Online Control

Efficient and robust data streaming services are a critical requirement of emerging grid applications, which are based on seamless interactions and coupling between geographically distributed application components. Furthermore the dynamism of grid environments and applications requires that these services be able to continually manage and optimize their operation based on system state and application requirements. This paper presents a design and implementation of such a self-managing data-streaming service based on online control strategies. A grid-based fusion workflow scenario is used to evaluate the service and demonstrate its feasibility and performance
