摘要: 现有网络服务(Web Services)容错方案存在资源开销大、与Web Services应用系统特性不一致等不足。针对该问题,根据Web Services应用系统特点提出基于服务替换的Web Services应用系统容错方法,其主要思想是在失效发生时使用网络中的等价服务替换失效服务。实验表明了该方法的可行性。

Abstract: Current Web Services fault-tolerant technologies cost too much resource due to their static configuration characteristics, and are inconsistent with the idiosyncrasy of Web Services systems. This paper proposes a fault-tolerant method employing service replacement strategy, which counts on the specialty of Web Services systems. The main idea of the strategy is replacing the invalid service with the equivalent service on Internet. The feasibility of this strategy is proved by experiment.

Key words: Web Services, fault tolerant, service replacing
