This paper proposes a Grid-based Distributed Simulation Platform (GDSP). It is designed to break the limitation of legacy simulation supporting platform and to meet new requirements from large-scale distributed and complicated systems. Simulation services are encapsulated by using web services technology, and they are basic elements of GDSP. With grid technology, GDSP enables users to share, access, and operate remote resource transparently. It is also easier to organize and manage simulation resources. GDSP improves the capability of fault tolerance and provides mechanism of using simulation resources securely. The research result shows that through this management mechanism, multiple users can share and monitor RTI resources, and manage the simulation collaboratively and effectively. At the same time, the impact on real time of RTI caused by the system is minimum.
