PaaS RTI-Supporting Distributed Simulation Interaction in Cloud Computing Age

In Cloud Computing age, distributed interaction simulation would encounter many difficulties, especially the WAN-based interaction. A scheme of remodeling the traditional RTI software to be with "Platform as a Service (PaaS)" architecture was proposed. This paper puts forward two different software architectures to adapt to different network environments. Kernel idea is encapsulating the APIs of traditional RTI to be Web Services, deploying and scheduling these Web Services on servers, so, a distributed interaction platform is provided to simulation users on WAN. Users could utilize the services from the platform to execute simulation interaction. Finally, an experiment was carried out to test the time-latency performance of the remodeled software.
