Research and Application on Virtualization Service Oriented Infrastructure for Networkitized M&S

This paper is presented based on paper and recent fruits gained by authors. The research background of a service oriented infrastructure for networkitized M&S, namely simulation grid, is firstly concisely introduced, then combined with authors' recent research on virtualization technology being applied to simulation grid, the phased research achievements of simulation grid are introduced in detail, including completed simulation grid prototype named Cosim-Grid 2.0v, some further solved key technologies and typical application demonstration systems on simulation grid. It is shown from the primary practice that the simulation grid developed by authors has the following new features: (1) The architecture of virtualization service oriented simulation grid overcomes shortcomings of traditional HLA application on dynamical share, autonomy, fault tolerant, capability of collaboration and security mechanism. (2) A simulation grid prototype named Cosim-Grid2.0v has independent copyright and is suitable for networkitized simulation application. It consists of simulation grid PSE, simulation application oriented service middleware, virtualization resource middleware and the virtualization simulation grid resources including various encapsulated and virtualized model resources, simulation tool resources, computing resources, storage resources, data resources and knowledge resources, etc.. (3) It extends simulation application pattern and implements new simulation method based on Internet and grid, such as the dynamic construct of simulation application on demand, the transparent application of heterogeneous simulation resources, the collaborative and universal operating environment, etc. Finally, the conclusion and some further works are given.

I. Introduction

At present, the tendency of system modeling and simulation technology is developing towards networkitization, virtualization, intelligentization, collaboratization and pervasivization[1]. The networkitized M&S technology is one of the studying hotspots existing in current M&S community. Outlining the development process of networkitized M&S, We can draw the conclusion that the technology connotation and application mode for networkitized M&S are always continuously extended and enriched with the development of network technology. The development process of networkitized M&S includes several typical development phases [2], such as DIS, ALSP and HLA [3]. Meanwhile, the combination of network technology (such as Internet, Web Service and Grid computing[4]), computer technology (such as HPC, virtualization) and HLA technology promote the generation and development of XMSF[5] technology and simulation grid technology. By using common technology, standard and open system architecture, it promotes the interoperability and reusability in the more range (especially including C4I system), overcomes the shortcomings existing in traditional HLA application (especially the limitation in the dynamic sharing, autonomy, fault tolerant and collaboration of simulation resource and the security application mechanism) [6].
