A Web Service Based-Architecture for Detecting Faults in Web Services

Web services are emerging as the standard paradigm for program-to-program interactions on Internet. They are gaining more and more momentum and their management is becoming critical. Fault management is one of the most challenging areas of network and service management. It includes fault detection, isolation and repair. This paper proposes a Web service based – architecture for detecting faults in Web services. The architecture is rooted in passive testing and its potential is demonstrated by a case study where we use it to detect faults in a Web service for conferencing. Passive testing consists of observing and analyzing the messages the component under test exchanges with its environment. The passive testers of our architecture are designed as Web services. Related work is discussed. The architecture is presented, and its potential is demonstrated.
