The High-Level Architecture (HLA) is the leading international standard for simulation interoperability. It originated in the defense communities but is increasingly used in other domains. This tutorial gives an introduction to the HLA standard.

It describes the requirements for interoperability, flexibility, composability and reuse and how HLA meets them. It shows how HLA can be used for LVC platform training, C2 training, analysis and wargaming as well as space simulation. Several standardized Federation Object Models (FOMs) like the RPR FOM model for platform training, Link 11 and Link 16 FOMs, NATO FOM, Cyber DEM and Space FOM are also described.

After an overview of the technical features of HLA, the new version, HLA 4, is described. It adds new features in the area of scalability, security, cloud and live deployment. New features for extending FOMs are also presented. Additional considerations like gateways, tool chain, performance and implementation of Cross Domain Securiy are also covered.

This tutorial is intended for all audiences; however, some familiarity with basic principles of distributed computing is recommended.
