5. DDS in simulation

6. DDS was born in 2003 as the real time backbone in Frigates…
… has now a full specktrum of applications

7. Why use DDS in Simulation?

SCALABILITY and FAULT TOLERANCE
• DDS has automatic discovery, is fully
publish-subscriber, no single point of
failure
• HLA is central server based: scalability
and fault tolerance are difficult

8. Why use DDS in Simulation?
LESS-THAN-PERFECT COMMUNICATIONS
• DDS has been proved over small
bandwidth (4800 bps)
• DDS can cope with heterogeneous
networks
REAL TIME SIMULATION
• Military platforms use DDS as the
communication backbone
• Simulating with DDS can incorporate
this data in real time

9. DDS vs HLA RTI

10. The LSA study group in
SISO

11. Rationale for SISO Layered Simulation
Architecture
Can we exploit these…
• Rationale for SISO Layered Simulation Advances in
Data-centric
Architecture
Net-centric
Middleware
interoperability
Open systems Simulation
architecture Architectures
…to improve these?

12. LSA study group in SISO
• In SISO fall 2012 an
LSA study group was
established
• Interim Progress
Report at 2013 Spring
SIW
• Final report fall 2013
Proposed LSA layer structure
http://www.sisostds.org/StandardsActivities/StudyGroups.aspx

13. Open LSA (Layered Simulation Architecture)
• A forum to explore and develop a consensus view of the applicability of modern
principles of network centric interoperability and open systems architecture
• Definition of different layers to enable looser coupling among simulation
applications will be addressed
LSA CORE
(*)Based on SISO LSA Study Group TOR

14. Focus of interest identified
From: LSA minutes Fall SIW 2012.pdf
Four different potential topics of interest
were identified:
1. Defining how to use DDS for
distributed simulation
2. Defining a gateway between DIS and
DDS
3. Defining a gateway between HLA and
DDS
4. Defining how to use DDS under the
HLA API

15. Liaisons with other groups
From: LSA minutes Fall SIW 2012.pdf
Liaisons with other groups has been
identified:
• http://www.sisostds.org/StandardsActiv
• C-BML: Use DDS as a transport

• BOM (Base object model): Extension of

models
• ANDEM SG: (Architecture Neutral Data • http://www.sisostds.org/StandardsActiv
Exchange Model) LSA data formats could ities/StudyGroups/ANDEMSGArchitectu

16. SimWare in a nutshell

17. SimWare: creating simulators
SimWare is a simulation framework for
creating new simulators from scratch
• Create new simulators
without seeing any
code
• Care only about data
model
• Simulation backbone
is DDS

18. SimWare: managing simulators
SimWare is a simulation framework for managing new simulators and old
simulators in joint simulation
• Manage your new
simulator
• Control the
instances of the
simulation
• Manage old
simulators in joint
simulations

19. SimWare: joint simulations
With SimWare you can manage joint simulator of existing HLA
and DIS simulators
• Connect and Life simulation
control
• DIS
• Pitch HLA
• Mäk HLA
• DDS
• Add DDS live
simulations
HLA federation Legacy simulation

20. Simware : THE IRC REVOLUTION
Interoperability Reusability
Composability

21. SimWare and the LSA
architecture model

22. How can SimWare fit into LSA model?
Model Driven M&S
Development Tool
RunTime Simulation
HLA RTI Infrastructure HLA RTI based on DDS
GW
DDS based Simulation Data Bus
Visual Tool for
Gateways
SimWare fits into LSA model !!!

23. SimWare aimed to LSA model
SimWare is growing towards LSA
• SimWare RTI: Will became a
complete HLA implementation
in 2013
• DIS-DDS bridges by using
SimWare will be available in
2013
• New developments in model
reusability are being proposed
aligned with LSA model
• DIS over DDS is being
considered
• NADS is an active participant
in LSA

24. Summary

25. Get involved with LSA
• LSA group need volunteers to complete its tasks
• LSA is the perfect framework to evolve simulation standards and
discuss new approaches to interoperability

26. Try now SimWare 4.2!!!
• Includes complete SimWare 4.2
• Also include the new SimWare RTI 1.2; HLA running over DDS without
data bridges
