摘要: In this paper, we present the design and implementation of a lightweight fault tolerance framework for Web services. With our framework, service can be rendered tolerant by replicating it across several nodes. A consensusbased algorithm is used to ensure total ordering requests replicated service, consistent membership view among replicas. The built extending an open-source WS-ReliableMessaging specification, all reliable message exchanges in conform specification. As such, does not depend on any proprietary messaging transport protocols, which with services principles. Our performance evaluation shows that nearly optimal incurs only moderate runtime overhead.
