Interservice Interoperability Training, Simulation and Education Conference IITSEC, December 2002, Orlando Florida Extensible Modeling and Simulation Framework (XMSF) Opportunities Don Brutzman and Michael Zyda Naval Postgraduate School Mark Pullen, George Mason University (GMU) Katherine L. Morse, SAIC Andreas Tolk, Old Dominion University (ODU)

2. Topics • XMSF problems, motivation, precepts, definition • Workshop synopsis • Symposium synopsis • Opportunities: C4I, M&S, Web, collaboration • Path forward XMSF Overview

3. Problems • Current approaches are not compatible with effective use of emerging Web technologies • Military modeling & simulation has little or no apparent impact on warfighters’ daily tactical operations • Diverse simulations do not scalably interoperate with warfighting systems • Global systems are not yet possible without connection to common interoperable framework • numerous physical and logical “stovepipes” prevent this XMSF Overview

4. Motivation • Transformational technologies are needed to scale up defense modeling/simulation to meet real-world needs • Can we use Web technologies as common framework? • Dynamic capabilities, open standards, Web business model provide lift to support government and commercial success • Easy use and open extensibility for developers and users, fueling rapid growth of interoperable simulations • Bring defense modeling/simulation/tactical support into mainstream of enterprise-wide best-business practices XMSF Overview

5. XMSF precepts • Web-based technologies can provide an extensible modeling and simulation architecture, to support a new generation of interoperable applications • Simulation support is needed for operational warfighting capabilities • XML-based architecture can provide a bridge between emerging rehearsal/reality/replay requirements and open/commercial Web standards • Web = best tech strategy + best business case XMSF Overview

6. XMSF Definition • The Extensible Modeling and Simulation Framework (XMSF) is defined as a set of Web-based technologies and services, applied within an extensible framework, that enables a new generation of modeling & simulation (M&S) applications to emerge, develop and interoperate. • Current work in Web Services appears to be an appropriate basis for organizing and composing the many necessary capabilities of Web/XML and Internet/networking needed for M&S applications. XMSF Overview

7. Preparing for change, quick start • Technical Challenges Workshop • NPS, August 19-20, focused expert efforts • Strategic Opportunities Symposium • George Mason University, September 6 – welcome! • Immediately precedes SIW for good participation • Broader feedback: right track? what else is needed? • Exemplar Demonstrations • I/ITSEC demos, Orlando Florida December 2-5 • Next steps for XMSF … • Establish partnerships with collaborators + sponsors XMSF Overview

8. XMSFTechnical Challenges Workshop • Monterey California USA, 19-20 August 2002 • preceding annual NPS MOVES Open House • Goal: initial technical survey and assessment • Modeling & Simulation via Web technologies feasible? • XMSF white paper provided basis for discussion • Report back to this group for strategic planning • Diverse technical experts invited in 3 areas • Web/XML, Internet/network, Modeling & Simulation • Point papers online, undiluted snapshots of key ideas XMSF Overview

9. Workshop Observations • Significant agreement, consensus on principles • Web technologies for networked modeling & simulation appears to be feasible and useful • Lots of different ideas about how to execute • Interestingly: few (if any) contradictions XMSF Overview

10. Workshop Conclusions 1, 2 • Close working relationship across all three technical areas will continue to be needed • Web / XML, Internet/networking, and M&S • Benefit from broad technical insights • Interrelated goals and concerns • XMSF approach must be further refined from a high-level concept to definitive technical recommendations, practices, and applications • Few (if any) new specifications are needed to proceed XMSF Overview

11. Workshop Conclusions 3, 4 • Need exemplar applications identified, initiated • Collectively and clearly demonstrate the application potential of XMSF concepts • A number of existing and emerging programs were discussed as possible contexts for the exemplars • Web Services • promising area for future work • sufficiently mature to begin exemplar systems XMSF Overview

12. Web Services XMSF Overview

13. Workshop Conclusions 5 • Security concerns are cross-cutting for all areas, must be addressed throughout design process • or unforeseen vulnerabilities occur • Approximately equal number of Web-related technical challenges & solutions presented • Likely feasible but recurring throughout lifecycle • Independent of classical physical/military security • NOT military classification • maybe: FOUO XMSF Overview

14. Symposium summary • Friday 6 September 2002, GMU Fairfax Virginia • Keynote address by Anita Jones: • “Modeling & Simulation is next killer app for Web” • Diverse speakers presented their considered opinions, in reaction to the workshop whitepaper • Across-the-board support for XMSF goals • Recognition: all need shared Web approach XMSF Overview

15. Opportunities: C4I, M&S, Web • Fall SIW 2002 showed many common goals : • C4I plenary, Rob Walker DISA COE program manager • C4ISR/Simulation Technical Reference Model report • Navy night, Gene Layman NRL • Web interoperability can expose legacy systems without major retooling of internals • changes connectivity challenge from 1-N hookups into N-N logic • Semantic interoperability possible, via oporder messaging • NPS exercising XML-MTF, Generic Hub (LC2IEDM), X3D, SVG • NUWC can ingest same XML oporder into submarine CCS XMSF Overview

16. Path forward • XMSF outreach • Report, demos, meetings, discussions, papers • I/ITSEC, Web3D Symposium, 2003 Spring SIW, Euro SIW • New partners: Andreas Tolk and Bowen Loftin, ODU VMASC • Mail lists live at http://www.MovesInstitute.org/xmsf/xmsf.html • Early-adopter collaborators and sponsor strategies • February 7, SAIC Tysons Corner, McLean Virginia • DMSO workshop on components/composability • Joint groups, SISO and Web3D Consortium • All feedback welcome XMSF Overview

20. Related work: workshop on software componentization • July 2002, DMSO, DC • two dozen attendees, POC Phil Zimmerman • SIW paper available 02F-SIW-052 • Consensus seemed to be: • components are a worthwhile approach to consider for improving composability and interoperability of diverse interacting simulations • component technology is sufficiently mature and well defined for building exemplars XMSF Overview

21. Workshop strategy 1 • How to solve big problems? Divide & conquer. • Three technical perspectives • Web technologies, XML • Internet and Networking • Modeling and simulation (M&S) • White paper lays out initial basic framework • please use, extend, correct, disagree XMSF Overview

22. Workshop strategy 2 • How to solve big problems? Divide & conquer. • Triage approach for all three technical areas: • What do we agree on: determine consensus • What do we disagree on: more work needed • What are most important directions for further work • Document workshop and symposium results • Most important outcomes may be education, direction XMSF Overview
