Overview for
Extensible Modeling and Simulation Framework



Background

In 2002 a small group of modeling and simulation experts from academia and industry, with partial DMSO support, undertook a study of the potential of Internet and Web technologies for interoperation of simulations with command and control (C2) systems. The study engaged a team of world-class experts and resulted in two workshops, study reports, and clear recommendations to pursue the benefits for these technologies for Defense M&S, under the label “Extensible Modeling and Simulation Framework (XMSF). ” The fundamental advantages are ease of interfacing heterogeneous systems for interoperation, availability of commercially-developed supporting technologies, and compatibility with the Web-based, Service Oriented Architecture planned for support of future C2 systems in the DoD Global Information Grid (GIG).

DMSO has supported ongoing efforts to demonstrate the potential of this approach and to expand the horizons of the defense M&S community into the high-potential capabilities of commercially-developed Web technologies, in particular the Web services approach to information exchange among distributed software systems. Activities of the community indicate that this combination of community outreach, standards body involvement, and implementation of exemplar projects has been successful in adding XMSF to the working set of technologies for Defense M&S.

Next steps for XMSF

Since the XMSF work began, it has become increasingly evident that C2 system interoperation with simulations offers a huge potential for improved information support to the warfighter, and that XMSF represents the best path to achieve this. DMSO is now considering the need to fill several gaps in the needed standards and technologies, including a consistent M&S Namespace for the M&S GIG Community of Interest (COI) and streaming/multicast Web service standards. The goal is to facilitate and demonstrate real-time M&S capabilities that can seamlessly interoperate with warfighter C2 applications, all via the Global Information Grid (GIG) using extensible Web services.
