System Design and Implementation: a Web-based Simulation Training System in Grid Environment

Recently, the web-based training has become one of the most essential and valuable themes in many kinds of fields. However, the information needed by simulation training operations is usually stored apart in those independent and autonomous software systems as current in practice, so it is difficult to be shared and utilized. And comparing with need of training system web application has some shortcomings such as interactivity and graphical user interface. A web-based simulation training System in grid computing environment (GWSTS) was proposed which used standard web tools and grid technology to promote the interoperability and reusability of simulation applications and link geographically dispersed simulation components. Both the runtime mechanism of the whole training system and how to invoke the grid services was discussed. To increase responsiveness and interactivity of web-based training, the Ajax technology was used to develop the training system. What's more, some ActiveX controls were designed to achieve the visualization of the dynamic simulation data. Application results show that the GWSTS is a promising alternative to existing network simulation gaining system.
