Meet DDS in simulation

DDS en otros ámbitos industriales

– In simulation– In RTES– In Scada– In Smart grids– In BI– In Medicine

DDS was born in 2003 as the real time backbone in Frigates…

Real time systems in Frigates

… has now a full spectrum of applications

CONTROLLING COMMUNICATION

• DDS is centered in controlling the communication

• HLA tries to minimize the communication. It cannot control it

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

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

HLA Run Time Infrastructure designed for real time performance in large federations

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

object management

ownership management

SimWare RTI : The first RTI to join DDS with HLA RTI

Communication + QoS
