This document discusses using the Data Distribution Service (DDS) as a High Level Architecture (HLA) Run Time Infrastructure (RTI). DDS was originally developed in 2003 for real-time communication in frigates and has since expanded to many industrial applications including simulation. Using DDS as an HLA RTI provides advantages like scalability, fault tolerance, and ability to handle less-than-perfect communications compared to a centralized HLA server. SimWare RTI is presented as the first RTI that joins DDS with HLA RTI to provide HLA services while leveraging the features, performance, and reliability of the DDS standard for data distribution without needing gateways.

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

6. Using DDS as a HLA RTI: Advantages
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

7. SimWare RTI : The first RTI to join DDS with HLA RTI
 HLA Run Time Infrastructure designed for real
time performance in large federations
1516 API
 IEEE 1516 HLA API for virtual and live
simulations
 Use DDS for Data Distribution  functionality
of an HLA RTI with the
features, performance, power and reliability of
OMG DDS standard
 No gateways needed to connect HLA to DDS
 Full HLA services support as required in virtual
& live simulations :
 federation management
 declaration management Communication + QoS
 object management
 ownership management

8. Hands on
Believing is good, seeing is better…
doing it is even better

9. Hands On Agenda  Installation of the product
 Structure of directories &
documentation
ETHERNET
 Environment variables
 License
 Communication layer: QoS
 Running the server
Windows
 Connecting a test client
 Running the test client
 Modifying and compiling the
test client; environment,
compilers, etc.
