AbstractWeb services add a language-independent layer for distributed applications. It is well motivated to use Web Services for e-science and e-learning applications, where resources-sharing is a demand. Online experimentation is one of the e-learning applications. Web Services have intrinsic weaknesses on latency and scalability due to more transport layers used. This paper presents our experiences in using Web services for prototyping a service-oriented architecture for Online Experiment Systems (OES). We present the methodology to wrap the functions of experimental devices into web services and the advance features the instrument web services should have. We benchmark the performance of this system when using SOAP as a wire format for Web Services. Our results show the degradation of the performance due to a large amount data to transfer. We present the solutions to optimize the performance.
