GDSA: A Grid-Based Distributed Simulation Architecture

This paper focuses on architecture suitable for large-scale simulation system. Based on the scenario of large-scale Internet simulation, the grid technology is introduced and a new architecture, GDSA is proposed. GDSA, a full grid-based architecture mainly focuses on four pending problems in distributed system: scalability, communications, management mechanism and QoS insurance computing environment. The advantages of grid in scalability and uniform communication will be used to improve system´s scalability and communication method. Management system will be built according to meta-service mechanism. Contractual computing mechanism (CCM), a special mechanism added in GDSA, will provide QoS insurance for users. Three-layer QoS model, which is the core of CCM, will take charge of QoS problems in different levels. At the end, a prototype is designed and the experiment results based on this platform show that GDSA is a promising system to overcome the pending problems in distributed simulation
