Abstract

Guaranteeing quality of service has been recently labeled as one of multiple major research challenges in the service oriented architecture. In effect, Web service selection from a set of matched services offering the same functional requirements, and ultimately claiming certain quality of service guarantees about themselves is not enough. A need emerges for the existence of a trusted third party that monitors Web service quality indicators, yet in a way that does not interfere with the normal operation of the Web service itself. The third party will eventually provide consumers with guarantees about Web service quality. In this research we propose a policy-based third party system for dynamically measuring relevant QoS metrics of a Web service, maintaining these measures for subsequent look-up requests and responding to QoS-aware service requests initiated by the clients. The system relies on a QoS-based architecture and a scheduling policy.
