Concept of Distributed Simulation
Simulations are interactive through current state-of-the-art communication systems
Constructive
Virtual
Live
Constructive
Virtual
Live
Can be across the world or across the room!
Simulation environments that are distributed across multiple computers, potentially at different locations
�Often referred to as “federations”

Distributed Simulations enable Joint Mission Training
CONSTRUCTIVE SIMULATION RED FORCES Injecting Red Forces in the scenario. Human behaviour represented by agents & IA
CONSTRUCTIVE SIMULATION BLUE FORCES Injecting Blue Forces in the scenario

Our Vision: Future of M&S systems is on the network
But Reality is Complex: * Different Standards for interoperability * Too many COTS hard to interoperate between them * Different Data & Voice Communications * Legacy vs. COTS based Systems * Heterogeneus simulation ecosystems * Scaling-Up to Very Large Exercises

Defense Administrations have invested a lot in simulation systems for weapon systems but: * Poor use of existing simulation assets * Distributed Mission Training is very difficult * Interoperability is very limited * Tied hands with HLA COTS vendors

Because of this problems, SISO starts a new Study Group : LSA, looking to solve many of this pains.
SISO LSA is looking to customize DDS for the simulation domain, providing the foundation for a Layered Simulation Architecture

Why use DDS in Simulation?
COMMUNICATION
DDS is centered in controlling the communication
HLA tries to minimize the communication. It cannot control it
DIS trust the communication

SCALABILITY and FAULT TOLERANCE
DDS has automatic discovery, is fully publish-subscriber, no single point of failure
HLA is central server based: scalability and fault tolerance are difficult

Why use DDS in Simulation?
LESS-THAN-PERFECT COMMUNICATIONS
DDS has been proved over small bandwidth (4800 bps in digital network radios)
DDS can cope with heterogeneous networks
REAL TIME SIMULATION
Military platforms use DDS as the communication backbone
Simulating with DDS can incorporate this data in real time

HLA and DIS cover more than the
70% of the demand. Both are
standards embraced by IEEE and
SISO and known worldwide
These architectures have significant
overlap in capabilities and
requirements

Simulation today: Use of different standards
Commercial in Confidence 12

A IEEE and NATO (Stanag 4603) standards
An accepted standard for interoperating simulators
Has meta-data model (OMT)
Define rules for interoperability
Many COTS from different vendors
Services are part of HLA
Wire protocol does not exist
The entire standard tries to limit communication
QoS are very limited.
Lack of plug&play capacities.
Performance is not enough for massive data distribution across heterogeneous networks.
API is hard to use
No security standard
Model is rigid
An assessment of HLA present capabilities

LSA looks to improve ROI in the S&T industry
Many architectures in use reduce reusability, interoperability and composability
LSA tries to improve this three key parameters
