A Fault Detection Mechanism for Fault-Tolerant SOA-Based Applications

Fault tolerance is an important capability for SOA-based applications, since it ensures the dynamic composition of services and improves the dependability of SOA-based applications. Fault detection is the first step of fault detection, so this paper focuses on fault detection, and puts forward a fault detection mechanism, which is based on the theories of artificial neural network and probability change point analysis rather than static service description, to detect the services that fail to satisfy performance requirements at runtime. This paper also gives reference model of fault-tolerance control center of enterprise services bus.
