摘要

本文演示了基于Web服务的n版本模型WS-FTM (Web服务容错机制)，该模型将这种久经考验的技术应用于Web服务领域，以提高系统的可靠性。WS-FTM通过使用修改后的存根实现对复制的Web服务的透明使用。存根是使用WS-FTM中包含的工具创建的。我们最初的实现包括一个允许通用结果比较的简单共识投票人。最后，通过使用一个重要的示例，我们展示了可以使用WS-FTM来提高Web服务系统的可靠性。

Increasing Web Service Dependability Through Consensus Voting

This paper demonstrates our Web Service based N-Version model, WS-FTM (Web Service-Fault Tolerance Mechanism), which applies this well proven technique to the domain of Web Services to increase system dependability. WS-FTM achieves transparent usage of replicated Web Services by use of a modified stub. The stub is created using tools included in WS-FTM. Our initial implementation includes a simple consensus voter that allows generic result comparison. Finally we show, through the use of a non-trivial example, that WS-FTM can be used to increase the reliability of a Web Service system.
