QoS analysis in service oriented computing
Additional Publication Information
Quality of Service (QoS) is a major concern in the design and management of a composite service. QoS analysis becomes increasingly challenging and important when complex and mission critical applications are built upon services with different QoS. Thus solid models and methods to support for QoS predication in service composition become crucial and will lay a foundation for further analysis of complexity and reliability in developing service oriented distributed applications. In this chapter, we introduce a framework for QoS aggregation in service composition. The QoS of the component services can be single values, discrete values with frequencies, or probability distributions. Experiments are carried out to demonstrate the effectiveness and efficiency of the introduced method.
