Practical Experiences from Four HLA Evolved Federations

ABSTRACT: HLA Evolved was formally published in 2010 but early federations based on this standard have been developed since 2008. This paper summarizes experiences from four federations during the period 2009 – 2011 with focus on maturity and on the use of new HLA Evolved features. The federations are as follows:

Viking 11 is the world’s premier joint civil-military-police exercise involving more than 2500 persons from 31 nations distributed across nine sites. The purpose is to acquire hands-on practical skills and knowledge of civilmilitary-police coordination and cooperation before deployment in multifunctional and multinational UN mandated peace operation. The exercise was successfully carried out in April 2011 using an HLA Evolved
infrastructure with participants running federates in different countries, proving the maturity of HLA Evolved.


NATO MSG-068 had the purpose to create a reference federation architecture for the NATO Education and Training Network with participants from, the US, UK, France, Germany, the Netherlands, Spain, Australia, Bulgaria, Romania, Turkey and Sweden. Participating systems include JCATS, JTLS, ICC, VBS2, WAGRAM, ORQUE, KORA and more. The HLA Evolved infrastructure proved to be stable during the experiment. HLA Evolved FOM Modules were used to mix standardized FOM data, like RPR with NATO extensions.

SISO Smackdown is a university outreach program, with participation from NASA and universities worldwide. Based on a lunar mission scenario it allows universities to extend the common information model to fit their part of the scenario. This extensibility is based on the HLA Evolved modular FOMs. Since this project uses RTIs from two different vendors it also illustrates how federations can benefit from the HLA Evolved Dynamic LinkCompatible APIs.

BAE Systems Command and Control Demo Federation. This is a proof of concept for fault tolerance and load balancing. It uses fail-over federates based on the new HLA Evolved functionality. Another feature is the use of
HLA Evolved Smart Update Rate Reduction for dynamic control of tactical data update rates on mobile devices.
The conclusion is that HLA Evolved is mature and that most of the new features have already been successfully used.
