A fault-tolerant web services architecture

Abstract

Web services have been enjoying great popularities in recent years. The high usability of the Web service is becoming a new focus for research. According to the demands of Web services, we present a fault-tolerant Web services architecture named FTWS based on the service approach and the reflection approach. Its characteristics are: (1) The fault-tolerant mechanisms are transparent, easy to use and also flexibly customized; (2) The fault-tolerant properties are flexibly configured; (3) The target service programmers almost needn't to care the fault-tolerant mechanisms. The Architecture is set forth in detail in the article. The workflow of the system is narrated by three states of a fault-tolerant Web service. © Springer-Verlag Berlin Heidelberg 2006.
