  • The system logic structure has innumerous effect to the development, execution, and scalability of multi-federation system. A multi-federation system based on tree-topology structure was provided. Federations in the system were connected through proxies. Each federation was connected only with federations directly upper and lower. Thus multi-channels and loops in data transmission were avoided. A strategy was also presented to synchronize time advancement in real time multi-federation systems using RTI (run-time infrastructure) time management. Time-regulation federates and time-constraint federates in multi-federation systems were settled specially to ensure that synchronization signals created in root federation could be transmitted to leaf federations through tree-topology. The synchronization of time advancement of the whole system was realized. The time delay of synchronization signals in system was also analyzed as a result a time-delay formula was given. This formula reveals that more levels in system structure would lead to more delay.
