Design and Implementation of Failover Federates Supporting Fault Tolerance for HLA Based Simulations
Yibo Han, Qun Wang, Wei Zhang · 2010
With the increasing scale and complexity of HLA based simulations, fault tolerance is gradually becoming a pressing problem. This paper addresses the challenges in realizing a failover federate to support fault tolerance for HLA based simulations. Based on the analysis of the fault tolerance problem, the failover federate is described firstly. It comprises a primary federate and a standby federate. Next, the failover federate is designed through exploiting the fault detection problem and fault tolerance dispatching method. Additionally, the implementation detail is explained. Through some testing, it proves that the reliability of the whole simulation systems can be promoted through the introduction of the standby federates.
