The High Level Architecture (HLA), standardized as the IEEE 1516-series, 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. The IEEE 1516 series of HLA specifications was originally approved by the IEEE Standards Activity (SA) Board in Fall 2000. Since that time, a DoD Interpretations Document for IEEE 1516, the Dynamic Link Compatible HLA API for IEEE 1516.1, and many other developments have identified improvements for the HLA specifications. As part of the periodic review and update of IEEE specifications, this Product Development Group has completed three review and update rounds for the HLA specifications addressing the improvements identified above. The revised specifications have recently completed an initial ballot and a recirculation ballot to address technical comments. The IEEE Standards Activity Board has approved publication of the new standards, and we are in final coordination with the IEEE editors.
