JWS-QoS: QoS Support Infrastructure for Web Services By John Trafecanty Advisor: Jiang Guo

Web Service Composition

Continued

Goals JWS-QoS Software system  QoS metrics Performance Reliability Composition

QoS Defined Performance  How fast a service request can be completed. Execution Time  The number of failures per time period. SOAP Faults  Performance guarantee per number of simultaneous requests. Execution Time of Simultaneous Requests

Web Services

Open Source jUDDI 0.9rc4 Apache Tomcat MySQL UDDI4J Apache Axis2 1.1 Apache Axis 1.4 WSDL4J JFreeChart 1.0.3
