QoS Composition and Analysis in Reconfigurable Web Services Choreographies

Abstract: Abstract-Quality of Service (QoS) in orchestrated web services compositions have been well studied with probabilistic and multi-dimensional models. Choreographies that involve message passing among services, on the other hand, require further analysis. In this paper, we begin with the set of QoS domains that may be studied in case of choreographies and the algebraic rules for their composition. As choreographies manage QoS composition in a distributed fashion, techniques to enrich functional specifications wit… Show more

“…In case this is not exposed, the worst case performance for each domain must be expected at design time. At runtime, if re-configuration [15] or replacement/late-binding occurs, changes that may be expected through varied interaction paradigms may be evaluated. For instance, reduced S may be traded off with improvements in δ.…”

“…While our previous work [15] studies the effect of choreography topology on the QoS, by fine-grained analysis of message interactions, we evaluate the performance of choreography participants in relation to heterogeneous paradigms. This methodology enables: 1) Design-time selection of interaction paradigms to match required functional and QoS goals, and 2) Runtime analysis of composed choreographies to prevent deterioration of end-to-end QoS of participants.…”

“…Among all topics in service computing, QoS-aware service selection and service composition are studied in a large number of literatures [15], [16], [17], [18], whose goal is to decide which candidate services to be used as components in complex systems. However, most of the research work has a necessary precondition: QoS values of all candidate services for corresponding users are already known, which is always not satisfied in real-world cases.…”
