Adaptive Algorithms for Finding Replacement Services in Autonomic Distributed Business Processes

Web service may be used to construct autonomic business processes, where several Web services interact with each other to carry out complex transactions or workflows. During the execution of an autonomic process, if one component service fails or becomes overloaded, a mechanism is needed to ensure that the running process is not interrupted and the failed service is quickly and efficiently replaced. In this paper, the authors present two algorithms to solve the problem. The first algorithm uses the backup path approach so that the predecessor of a failed service may quickly switch to a predefined backup path. The second algorithm uses the replacement path approach to re-construct a new process by skipping a failed service.
