| Summary: | 碩士 === 國立臺灣師範大學 === 資訊工程研究所 === 93 === Web services are Web-based enterprise applications that use open, XML-based standards and transport protocols to exchange data with calling clients. In this paper, we demonstrate Web services can be applied to construct a distributed file system. We propose the Web services based network file system (WSNFS). One of the goals of the WSNFS is that it provides a platform for the file sharing among heterogeneous distributed file systems, which can offer access to users’ data, anytime, anywhere, in a transparent manner. Also, as the technology of Web services has a widespread application to the field of grid computing, the proposed system can help with the deployment of Web services to the data grid application. We present the architecture of WSNFS and define the standard of the communication protocol based on Web services. The experiences in implementing the prototype as well as the experimental results demonstrate that the WSNFS is very practical. The performance of the prototype is competent compared with SUN network file system.
