A research on error handling model of service fault-tolerant strategy

With the rapid development of web services, web services fault-tolerant mechanism has become a new research focus. This paper presents an innovative error handling model of service fault-tolerant strategy. For the goal of enhancing the fault-tolerant performance of web services, we analyze the key technologies of web services fault-tolerant in detail, propose the concept of fault-tolerant strategy, describe the service faulttolerant model mechanism, show the life cycle and the state transition of service in this model, as well as the working mechanism of fault-tolerant mode. And the model has been applied in the project of “maritime and shipping integrated system of Yunnan Province”. As this model has the characteristics of flexibility and platform independence, it has received a good practical application, greatly enhance the user experience. The feasibility rationality and effectiveness of the model has been proved. Keywordserror handling; fault-tolerant strategy;web service
