SLA Requirement Generation and Implementation Algorithm Selection for Service Composition Based on QoS Reference Vector

Category: IT Management, Networking and Communications

Overview Under SOA, composite service is formed by aggregating multiple component services together in given workflow. One key criterion of this research is QoS composition. Most work on service composition focuses on the algorithms about how to compose services according to assumed service level agreement. This paper proposes to strengthen current service composition mechanism by adding generation of QoS requirement and its implementation algorithm selection based on the QoS reference vectors which are calculated optimally from the existing individual services' QoS by registry to represent QoS overview about the best QoS, the worst QoS, or the average QoS of all composite services.
