•
•
•
•
•

Interoperability between
simulated and operational
systems
Development and maintenance
of Simulation assets using MDA
(Model Driven Architecture)
Deployment of simulation assets
as services into an HLA
federation

6. WHAT IS DIFFERENT IN NOGESI SOLUTION
• Traditional approach
• Implement a simulation engineering methodology, like FEDEP
/ DSEEP
• For the deployment
• Wrapper or middleware that provides an abstraction of
different simulation protocols like HLA, DIS or TENA
• Gateways and bridges between the different types of
simulators
• Advanced simulation services like execution, ownership or time
management are unavailable
2013 Fall SIW

7. The architecture as THE key point
• Main innovations in NOGESI are not in the development process but
in the simulation technical architecture.
• NOGESI is based on LSA, a pure distributed data-centric architecture
2013 Fall SIW

8. ARCHITECTURE OF THE SOLUTION
• Use of DDS in conjunction with HLA and DIS standards
• NOGESI follows LSA architectural proposal

Simulation
engine
 Scheduler: Is an advanced scheduler for controlling the real time clock and the
state machine. It coordinates and balances many Simulation Engines that are in
different nodes.
 Simulation Engines: Are the simulation engines, manage the Simulation modules
in each simulation node.

17. Control of NOGESI: ACS
 ACS—Application to Control SimWare simulations, is a GUI that allows to
manage SimWare state machine and simulation assets’ parameters during
execution

18. Reusable Gateways
2013 Fall SIW

19. NOGESI key points
2013 Fall SIW

20. Key point 1: Reusability
• Nogesi allows to reuse simulation models and services
 These models can be deployed in any scenario
 Models can be changed by editing a file
• Nogesi can incorporate already existing simulators and
legacy simulators
• Any COTS using HLA or DIS can be incorporated
2013 Fall SIW

21. Key point 2: Extensibility
• Nogesi can be extended to include new COTS not tested or
included on the original project
• Already tested with STAGE 6.1.1 and 6.2 and Vega Prime
2013 Fall SIW

22. Key point 3: Cost savings
• Nogesi allow a clear saving in costs by:
 Reusing previous existing models
 Leaving existing HLA and DIS
federations “as is”
 Incorporating already purchased
COTS
 Adding legacy elements/simulators
 Connecting different HLA vendors
 Allowing new COTS not tested before
2013 Fall SIW

23. NOGESI as a simulation
black-box
2013 Fall SIW

24. Nogesi as a simulation black box
• Can be deployed anywhere
• Can connect to any HLA or DIS compatible COTS
• Can be fully distributed

27. Next Challenges
• Extension of Nogesi has new challenges
 Wan interconnection using DDS: Qos file and Qos patterns
 Compensation of network latencies
 Network requirements and limitations: dedicated network
vs general network
 Security requirements: What security is really needed?
