José Ramón Martínez presented a proposed structural organization for the LSA architecture. He outlined a layered structure with DDS as the communication layer, proposed exploring common data models and simulation services, and discussed interfaces with other standards like HLA, DIS and TENA. Martínez called for involvement in LSA working groups to debate issues and work on tasks to advance the standardization effort.
Structural organization of LSA architecture
- 1. Structural organization of LSA architecture Presented by Jose R Martinez 2013 Spring SIW
- 2. Speaker José Ramón Martínez Salio MSc Industrial Engineering AGENDA Presales Team Director NADS LSA manifesto Some exquisite dissections A call for action jrmartinez@nads.es Questions Total time 30 minutes 2013 Spring SIW
- 3. Slicing LSA: rationale • LSA cannot be afforded as a whole • Divide and conquer • Make people responsible • Debate, debate, debate Proposed LSA layer structure http://www.sisostds.org/StandardsActivities/StudyGroups.aspx 2013 Spring SIW
- 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 LSA CORE (*)Based on SISO LSA Study Group TOR 2013 Spring SIW
- 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 2013 Spring SIW
- 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 2013 Spring SIW

- 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!!! 2013 Spring SIW
