IEEE 1516.1-2000

This document defines the interface between federates (simulations, supporting utilities, or interfaces to live systems) and the underlying software services that support inter-federate communication in a distributed simulation domain. The High Level Architecture (HLA) has been developed to provide a common architecture for distributed, computer-based modeling and simulation. To facilitate inter-federate communications, HLA federates interact with a runtime infrastructure (analogous to a special-purpose distributed operating system) using a standard application program interface. This specification defines the standard services and interfaces to be used by the federates in order to support efficient information exchange when participating in a distributed federation execution. A federation execution occurs when sets of federates are brought together to support an objective. New IEEE Standard - Superseded. The high level architecture (HLA) has been developed to provide a common architecture for distributed modeling and simulation. The HLA defines an integrated approach that provides a common framework for the interconnection of interacting simulations. This document, the second in a family of three related HLA documents, defines the standard services of and interfaces to the HLA Runtime Infrastructure (RTI). These services are used by the interacting simulations to achieve a coordinated exchange of information when they participate in a distributed federation. The standards contained in this architecture are interrelated and need to be considered as a product set, when changes are made. They each have value independently.
