AGENDA
LSA manifesto Some exquisite
dissections A call for action Questions
2013 Spring SIW
Slicing LSA: rationale
• LSA cannot be afforded as a whole
• Divide and conquer• Make people responsible• Debate, debate, debate
Proposed LSA layer structure

LSA manifesto
A program of action1. Establish a logical
division2. Create work groups3. Assign responsibles4. Decide some initial
tasks5. Create threads6. Work on it!

Some exquisite dissections

LSA CORE
2013 Spring SIW
• 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
DDS communication layer
– In simulation– In RTES– In Scada– In Smart grids– In BI– In Medicine
Real time systems in Frigates
2013…2003
2013 Spring SIW
• 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?
Common data model
2013 Spring SIW
• 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
Simulation services
2013 Spring SIW
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?
Interfaces with another standards: HLA, DIS and TENA
HLA DIS
2013 Spring SIW
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
Interfaces with another standards: HLA, DIS and TENA

Liaisons with other groupsFrom: LSA minutes Fall SIW 2012.pdf
Liaisons with other groups has been identified:
• C-BML: Use DDS as a transport alternative
• BOM (Base object model): Extension of the models and distribution of the models
• ANDEM SG: (Architecture Neutral Data Exchange Model) LSA data formats could be interesting for this group
• DDS OMG: The standard can be evolved if needed

2013 Spring SIW
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
