Design and implementation of fault-tolerant mechanism in BH RTI

The architecture integrated of distributed peer-to-peer physical structure and hierarchical logical supervisory structure was adopted. The critical information redundancy was made, such as RTI identity, and federation execution supervisory, and then the runtime condition of each RTI was detected, and also the architecture was rebuilt in time. The experimental results show that this mechanism can detect and locate faults, mask and restore from it, and can meet the requirement of fault-tolerance in HLA applications.
