The fault monitoring federate pattern This design pattern prescribes a federate that monitors and detects faults in the federation and takes some action to handle the fault.

A number of extensions for fault tolerance have been developed for the HLA Evolved standard. The new functionality has been accepted during the first HLA Evolved comment round. This paper provides some insights into the development process for these extensions as well as some alternatives that were initially considered. Our initial discussions abou...

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.
