Web services have emerged as a technology that aims at improving the communication between applications, through the service-oriented paradigm. Researches involving web semantics, ontology and composition of services has currently been developed. However, research in performance evaluating of web services architecture with quality of service support (QoS) is little widespread. Some works separately approach techniques as composition of Web services and models of architectures to improve the quality of Web services. Considering the lack of work involving jointly these different boarding, the purpose of this work is show a performance evaluating of a prototype architecture named WSARCH (Web Services Architecture) that relating quality of service attributes. The initial prototype of the architecture already allows investigate new ways of evaluating performance of Web services based on a contract model and improved existing service discovery solution though the incorporation of quality-of-service issues and related metrics for ranking matches.
