Abstract
Abstract. There are many problems hindering the design and development of Service-Oriented Architectures (SOAs), which can dynamically discover and compose multiple services so that the quality of the composite service is measured by its End-to-End (E2E) quality, rather than that of individual services in isolation. The diversity and complexity of QoS constraints further limit the widescale adoption of QoS-aware SOA. We propose extensions to current OWL-S service description mechanisms to describe QoS information of all the candidate services. Our middleware based solution, AMPol-Q, enables clients to discover, select, compose, and monitor services that fulfil E2E QoS constraints. Our implementation and case studies demonstrate how AMPol-Q can accomplish these goals for web services that implement messaging.
