Design and implementation of HLA time management in the RTI version F.0

The DoD High Level architecture (HLA) has recently become the required method for the interconnection of all DoD computer simulations. The HLA addresses the rules by which simulations are designed to facilitate interoperability, the method by which information exchanged between simulations is described, and a standard set of software services provided 5y a common Runtime Infrastructure (RTI). The RTI is responsible for the coordination of collections of cooperating simulations. The familiarization version of the RTI, dubbed F.0, was developed at the MITRE Corporation. One of the core components of the RTI is Time Management and is the focus of this paper. In particular, we present the design and algorithms used to implement the HLA Time Management Services in F.O.
