NOGESI requisites and solutions

2013 Fall SIW

Nogesi Challenges• Integration of legacy systems

and COTS• Interoperability between

simulated and operational systems

• Development and maintenance of Simulation assets using MDA (Model Driven Architecture)

• Deployment of simulation assets as services into an HLA federation

• HLA full interoperability including ownership transfer

2013 Fall SIW

Nogesi needs of integration

• Integration of legacy systems, HLA and DIS-based COTS

WHAT IS DIFFERENT IN NOGESI SOLUTION• Traditional approach

• Implement a simulation engineering methodology, like FEDEP / DSEEP

• For the deployment• Wrapper or middleware that provides an abstraction of

different simulation protocols like HLA, DIS or TENA• Gateways and bridges between the different types of

simulators

• Advanced simulation services like execution, ownership or time management are unavailable

2013 Fall SIW

The architecture as THE key point

• Main innovations in NOGESI are not in the development process but in the simulation technical architecture.

• NOGESI is based on LSA, a pure distributed data-centric architecture

2013 Fall SIW

ARCHITECTURE OF THE SOLUTION• Use of DDS in conjunction with HLA and DIS standards• NOGESI follows LSA architectural proposal

ACS

On the Core: eHost for Simulation management

Scheduler: Is an advanced scheduler for controlling the real time clock and the state machine. It coordinates and balances many Simulation Engines that are in different nodes.

Simulation Engines: Are the simulation engines, manage the Simulation modules in each simulation node.

2013 Fall SIW

ACS—Application to Control SimWare simulations, is a GUI that allows to manage SimWare state machine and simulation assets’ parameters during execution

Reusable Gateways

2013 Fall SIW

NOGESI key points

2013 Fall SIW

Key point 1: Reusability

• Nogesi allows to reuse simulation models and services These models can be deployed in any scenario Models can be changed by editing a file

• Nogesi can incorporate already existing simulators and legacy simulators

• Any COTS using HLA or DIS can be incorporated

2013 Fall SIW

Key point 2: Extensibility

• Nogesi can be extended to include new COTS not tested or included on the original project

• Already tested with STAGE 6.1.1 and 6.2 and Vega Prime

2013 Fall SIW

Key point 3: Cost savings

• Nogesi allow a clear saving in costs by: Reusing previous existing models Leaving existing HLA and DIS

federations “as is” Incorporating already purchased

COTS Adding legacy elements/simulators Connecting different HLA vendors Allowing new COTS not tested before
