High Level Architecture Data Distribution Management migration from DoD 1.3 to IEEE 1516

摘要

The High Level Architecture (HLA) is an infrastructure for assembling federations of distributed simulations, or federates, that interoperate by exchanging simulation data at run time. HLA's Data Distribution Management (DDM) services control the amount of simulation data delivered to an HLA federate by establishing dynamic data communications connections based on the federates' run-tune declarations of data production and requirements. In September 2000 the Institute for Electrical and Electronic Engineers (IEEE) approved a new standard for HLA, the IEEE 1516 standard. Most parts of the IEEE 1516 standard are generally similar to the U.S. Department of Defense HLA standard upon which it was based, the DoD 1.3 standard. However, the DDM services were significantly changed in the IEEE 1516 standard. The changes to DDM included the removal of routing spaces and the introduction of default dimension ranges. These changes simplified the implementation of some approaches to using DDM, but they did not affect the fundamental functionality of DDM. With some care, HLA users can develop DDM usage approaches that can be migrated smoothly from DoD 1.3 to IEEE 1516.
