What is HLA? The high-level architecture (HLA) is a general purpose architecture for distributed computer simulation systems. Using HLA, computer simulations can interact (that is, to communicate data, and to synchronize actions) with other computer simulations regardless of the computing platforms. HLA is an interoperability standard for distributed simulation used to support analysis, engineering and training in a number of different domains in both military and civilian applications and is the standard technical architecture for all US Department of Defense simulations.
