An Approach for QoS Based Fault Reconfiguration in Service Oriented Architecture

Web services and service-oriented style of architecture becomes the basis for a new generation of distributed applications and system management tools. With such deployments, Quality of Service (QoS) properties such as response time, availability and service costs are in high demands for SOA-based interoperability. There may be situations where services become faulty, resulting in violation of end to end QoS constraints. The work focuses on identifying the faulty services and their replacement on the basis of QoS constraints. Instead of modifying the whole composition, reconfiguration of the faulty region shall reduce the overheads of computations and service distractions in service delivery.
