Path forward
IITSEC, December 2-5 2002XMSF 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
IITSEC, December 2-5 2002XMSF 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
IITSEC, December 2-5 2002XMSF 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
IITSEC, December 2-5 2002XMSF 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.

XMSFTechnical Challenges Workshop
Monterey California USA, 19-20 August 2002preceding annual NPS MOVES Open House
Goal: initial technical survey and assessmentModeling & Simulation via Web technologies feasible?XMSF white paper provided basis for discussionReport back to this group for strategic planning
Diverse technical experts invited in 3 areasWeb/XML, Internet/network, Modeling & SimulationPoint papers online, undiluted snapshots of key ideas
IITSEC, December 2-5 2002XMSF 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
IITSEC, December 2-5 2002XMSF Overview 10
Workshop Conclusions 1, 2
Close working relationship across all three technical areas will continue to be neededWeb / 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 applicationsFew (if any) new specifications are needed to proceed
IITSEC, December 2-5 2002XMSF Overview 11
Workshop Conclusions 3, 4
Need exemplar applications identified, initiatedCollectively and clearly demonstrate the application
potential of XMSF conceptsA number of existing and emerging programs were
discussed as possible contexts for the exemplars
Web Servicespromising area for future worksufficiently mature to begin exemplar systems

Workshop Conclusions 5
Security concerns are cross-cutting for all areas, must be addressed throughout design processor unforeseen vulnerabilities occurApproximately equal number of Web-related technical
challenges & solutions presentedLikely feasible but recurring throughout lifecycle Independent of classical physical/military security

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
IITSEC, December 2-5 2002XMSF 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

Related work: workshop on software componentization
July 2002, DMSO, DC two dozen attendees, POC Phil ZimmermanSIW 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

Workshop strategy 1
How to solve big problems? Divide & conquer.
Three technical perspectivesWeb technologies, XML Internet and NetworkingModeling and simulation (M&S)
White paper lays out initial basic frameworkplease use, extend, correct, disagree
IITSEC, December 2-5 2002XMSF 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 consensusWhat do we disagree on: more work neededWhat are most important directions for further work
Document workshop and symposium resultsMost important outcomes may be education, direction

redundancy, etc.
Security levels consistent with current Web technology
Public library of useful reusable components
Cross-platform capabilities
Rendering support and architectural hooks for visual simulations
IITSEC, December 2-5 2002XMSF Overview 27
Top-Level Requirements 4
Expected computer performance: Small, fast, inexpensive computers

OC3 up through gigabit wide-area networking
Backward compatibility with existing architectures and protocols, where it makes sense
e.g. DIS, HLA/RTI, ALSP, probably many others
