Towards massive distributed SimulationTowards massive distributed Simulation

The Navy identified networked trainers as a key requirement in future training systems. Networking capability exists in many simulators, but frequently the capability is cumbersome to set up and difficult to use, particularly when participants are not collocated. In addition, the speed is not yet available to support the requirements for real time simulation across distributed networks. There are work-arounds, but they do not currently support full, real time simulations. The ability to easily and seamlessly link multiple training devices into the same training scenario will greatly enhance the quality and effectiveness of the training. […]Effective networking of simulators will require a common architecture and industry wide standards. Over the years, the High Level Architecture has provided the foundation for this standard, but going forward these standards will need to expand to accommodate new capabilities and new participants. The NASMP needs normalized, consistent architecture and a well articulated business case to justify the investment in the NASMP.

Our assessment of HLA …Our assessment of HLA …

□ Pros…Pros…▪ A IEEE and NATO (Stanag 4603) std.▪ An accepted std for interoperating simulators.▪ The meta-data model (OMT)▪ Define rules for interoperability.▪ Many COTS from different vendors.

□ Cons…Cons…▪ Wire protocol does not exist.▪ QoS are very limited. ▪ No seamless integration with RT critical systems.▪ Performances are not enough for massive data

Some use cases

WWW.NADS.ES


The OMG Data Distribution Service for The OMG Data Distribution Service for Real -Time Systems (DDS)Real -Time Systems (DDS)

Introduced in 2004 to address the Data Distribution challenges faced by a wide class of Defense and Aerospace Applications

Key requirement for the standard were to deliver very high, predictable, performance while scaling from embedded to ultra-large-scale deployments

Recommended by key administrations worldwide (Us Navy OACE, DISA, Eurocontrol, QinetiQ)

Widely adopted across several different domains, e.g., Trading, Simulations, SCADA, Telemetry, Mission Systems, Air Traffic Management, etc.
