Abstract :
Web-based Virtual Laboratory is emerging as a promising teaching assistant tool for modern distance education and attracts many attentions from both of academia and industry. In this paper, a novel virtual laboratory platform based on dynamic service composition, which is named as VL-DSC, is presented. In this platform, experimental process can be customized by service virtualization. A domain-oriented service composition description language is designed to describe the relationship between heterogeneous virtual instruments. Furthermore, based on the description language, dynamic message routing is adopted to realize dynamic schedule and replacement of virtual instruments. VL-DSC can significantly improve the customizability and dynamic interoperability of virtual lab, which can be used to develop virtual lab easily and quickly.
