This document defines the processes and procedures that should be followed by users of the High Level Architecture (HLA) to develop and execute federations. It is not intended to replace low-level management and systems engineering practices native to HLA user organizations, but is rather intended as a higher-level framework into which such practices can be integrated and tailored for specific uses. The High Level Architecture (HLA) has been developed to provide a common architecture for modeling and simulation. An HLA federation is a named set of software applications (federates) that interact via the services of the HLA Runtime Infrastructure (RTI) in accordance with a common object model in order to achieve some objective (or set of objectives). The purpose of this document is to provide the HLA user community with a recommended practice for how HLA federations are developed and executed. New IEEE Standard - Superseded. The processes and procedures that should be followed by users of the High Level Architecture (HLA) to develop and execute federations are defined in this recommended practice. This recommended practice is not intended to replace low-level management and systems engineering practices native to HLA user organizations, but is rather intended as a higher-level framework into which such practices can be integrated and tailored for specific uses.
