Abstract

This paper addresses QoS management for self-healing Web services. The objective is to provide a healing frame- work based on service monitoring and architectural-level repair actions. We address these topics in the context of the European project WS-DIAMOND. We implemented and assessed a connector-based healing layer capable of inter- cepting, analyzing and enhancing SOAP traffic and message contents with QoS data. Our framework supports Service Monitoring and dynamic run-time reconfiguration based on reflective programming. key words: Self-healing Web services, QoS management, reconfiguration, repair, service monitoring.
