The High Level Architecture (HLA) is a standard for distributed simulation, used when building a simulation for a larger purpose by combining (federating) several simulations. [1] The standard was developed in the 1990s under the leadership of the US Department of Defense [ 2 ] and was later transitioned to become an open international IEEE ...
It is a High Level Architecture (HLA) federation object model developed for distributed simulation applications of defense and security. [1] RPR FOM is listed in the NATO Modelling and Simulation Standards Profile AMSP-01. [2] The RPR FOM provides backwards compatibility with simulations using the Distributed Interactive Simulation (DIS) standard.
In simulation, run-time infrastructure (RTI) is a middleware that is required when implementing the High Level Architecture (HLA). RTI is the fundamental component of HLA. It provides a set of software services that are necessary to support federates to coordinate their operations and data exchange during a runtime execution. In other sense, it ...
MAK Technologies, formerly doing business as VT MAK, Inc. is a software company based in Cambridge, Massachusetts that provides commercial off-the-shelf (COTS) modeling and simulation software. The company develops and sells software for distributed simulations that system integrators, governments, and research institutions use to build and ...
HLA was produced by the merger of the DIS protocol with the Aggregate Level Simulation Protocol (ALSP) designed by MITRE. There was a NATO standardisation agreement ( STANAG 4482, Standardised Information Technology Protocols for Distributed Interactive Simulation (DIS) , adopted in 1995) on DIS for modelling and simulation interoperability.
The Aggregate Level Simulation Protocol (ALSP) is a protocol and supporting software that enables simulations to interoperate with one another. Replaced by the High Level Architecture (simulation) (HLA), it was used by the US military to link analytic and training simulations.
The area of software architecture was only recently adopted in 2007 by ISO as ISO/IEC 42010:2007. Integration is routinely described using the methods of architectural and software patterns. The functional elements of integration can be understood due to universality of integration patterns, e.g. Mediation (intra-communication) and Federation ...
