Research Of Web Services Reliable Messaging And Fault Tolerance Mechanism

With the development of information and enterprises' improving requirements to, the operational environment, especially the stability of mission-critical environment, the enterprises urgently need to make heterogeneous application, which can facilitate the cross-platform communication, loosely coupled, and easily to managed information interaction within the network environment. And this leads to the new technology of web services.For the differences of Internet based operating system and network environment, web services can not provide mature support for complicated application of high-availability, in terms of reliability and fault-tolerant performance. Up to now, there is not widely accepted sound mechanism. In the new research, the reliable message transmission and to perfect the service has become the hot issue.Backed with application of cross-platform distributed system, and based on existing web services standards, this paper makes researches on the reliable message transmission mechanism and fault-tolerant issue of web services system, based on which an alarm system for web-service-based enterprise server logs.This paper makes research on the following subject:Firstly, this paper researches the relevant concepts of web services, technical components, web services standards, and points out imperfections of the current web services.Secondly, this paper researches fault-tolerant mechanism in distributed system, and measures of it. Fault-tolerant framework of high availability, based on the web services, is designed with related technology. And three fault-tolerant strategies described the components and operating process in detail. Finally, this paper introduces the enterprises' requirements to reliability and tolerant performance of its log system, and designs log alarm system with reliable message transmission technique and fault-tolerant technique.This paper makes researches on the reliability and service-fault-tolerant performance of within system message transmission based on web services technique, which will be a help to improve the web services reliability and its application in mission critical area.
