The hierarchical federation architecture for the interoperability of ROK and US simulations

This paper presents the hierarchical federation architecture as it applies to the ROK-US combined exercises, such as Ulchi Focus Lens (UFL). We have analyzed and extracted the necessary improvements through the review of the simulation architecture currently used for ROK-US combined exercises and from the current ROK Armed Forces modeling and simulation (M&S) utilization. We have designed an advanced federation architecture based on a multi-federation architecture. Moreover, we have validated the usability and technical risks of our proposed architecture through development of a pilot system and its testing. Finally, we expect that this architecture will provide an enhancement in the ROK-US combined exercises while reducing costs. Furthermore, we believe that this architecture is an example to interoperate simulations with other allies.
