With HEART Towards Response Time Guarantees for Message-Based e-Services.

The {HEART} tool (Help for Ensuring Acceptable Response Times) has been developed by the {IT} Research and Innovations department of Dresdner Bank for the computation of viable message prioritization in message-based e-services, such as stock brokerage services where service requests of different customer classes with class-specific performance goals have to be served by a server. {HEART} determines viable message prioritizations in the sense that they satisfy the specified performance goals of customer classes. In this paper, we describe the practical problem setting we address with {HEART} and outline the functionality of {HEART}. The demo will show {HEART}'s underlying concepts, its architecture and an example scenario
