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!

Layers Overview

Data-centric Middleware: OMG DDSIOpen Wire protocol

Simulation Services

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
