Total time 30 minutes

3. Slicing LSA: rationale
• LSA cannot be afforded
as a whole
• Divide and conquer
• Make people
responsible
• Debate, debate, debate

4. LSA manifesto
A program of action
1. Establish a logical
division
2. Create work groups
3. Assign responsibles
4. Decide some initial
tasks
5. Create threads
6. Work on it!
2013 Spring SIW

5. Layers Overview
Simulators; new and existing (included legacy)
Current simulation architectures; HLA, DIS, TENA DDS simulators
Arch specific APIs Gateways
Simulators HLA Services New Services
HLA DIS TENA Simulation Services
DDS DDS DDS Common interface
Data-centric Middleware: OMG DDSI
Open Wire protocol
2013 Spring SIW

6. Some exquisite dissections
1. DDS communication layer
2. Common data model: e.g. state machine
3. Simulation Services
4. Interfaces with another standards: HLA, DIS and TENA
5. Interfaces with another SISO groups

7. DDS communication layer
• DDS communication layer
– Explore the limits: Wan and internet
– Security in communications: what are the real simulation
necessities? Do they fit the standard?
– DDSI evolution
– Possible specific evolutions of DDS for simulation
– In simulation
– In RTES
– In Scada
– In Smart grids
Real time systems in
Frigates
– In BI
– In Medicine

8. Common data model
• Do we really need to define a common data model?
– State machine model
– Rigid model vs flexible model
– Common schema or metamodel? Include QoS on it.
– Specific models for specific functions: e.g. loading simulation
models
– Relation with ANDEM: do we aim the same targets?
2013 Spring SIW

9. Simulation services
• Simulation services
– Addressing HLA services: time management
– Going beyond HLA services: e.g. latency service
– Common and minimum API for interfacing
– Common data modeling?
– The need for a Standard for services/certification of services
2013 Spring SIW

10. Interfaces with another standards: HLA, DIS and TENA
Adding up, never fighting against the other standards is
the key :
– Direct API with the standards
– HLA, DIS and TENA build over DDS without data bridges
– Alignment with LVCAR study objectives
– Can we evolve the standards or just bring them together?
2013 Spring SIW

11. Interfaces with another standards: HLA, DIS and TENA
Gateways/data bridges:
– Standardization of internal architecture
– Additional/support functions: establishing a minimum set
• coordinates conversion
• dead reckoning, smoothing
– Can we apply/change/refresh current standards to
guarantee a minimum? LVC-IME Capability Pattern

13. A call for action
We need:
• Your involvement
• Debate, debate, debate
Volunteer to:
• LEAD an area
• Add new elements to an area
• Do some tasks in an area
• Debate in a forum
LSA can only grow up with your expertise
GET INVOLVED!!!
