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 eservices, 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.
