Quality of Service in Event-based Systems

Future software systems must be responsive to events and must be able to adapt the software to enhance business processes. Examples are production and logistics processes that must be rescheduled based on relevant traffic information. It is therefore essential that relevant events are detected and transported to the software components responsible for dynamic changes. The trust in such reactive systems depends to a large extent on the Quality of Service (QoS) provided by the underlying event system. This paper introduces QoS aspects in event-based systems and discusses ways of identifying and evaluating QoS needs. This is done by identifying the different system layers, and the quality requirements at each layer based on the layer’s functionality. 1

Towards Benchmarking of AMQP

With the increasing importance of event-based systems the performance of underlying event transporting systems, such as message oriented middleware (MOM), becomes business critical. Therefore, we see a strong need for benchmark
