  1. High Level Architecture (HLA) Derek Bryan CS 775 09/29/03

  2. Agenda • Introduction • Components • Implementation • Examples • Questions

  3. Introduction • Developed by the Defense Modeling and Simulation Office (DMSO) • IEEE Standard – 1516 • DoD mandate for distributed simulation interoperability • Successor to Distributed Interactive Simulation (DIS)

  4. Components • A set of rules for federates and federations which defines relationships among compliant simulations. • An Object Model Template (OMT) specification which specifies the form in which simulation elements are described. • An interface specification that describes the way compliant simulations interact via the RTI (RunTime Infrastructure).

  6. Live Participants Interfaces toLive Players Federation Support Tools Federates Interface Runtime Infrastructure (RTI) Federation Management Declaration Management Object Management Ownership Management Time Management Data Distribution Management Operating System Components (3)

  7. Implementation • RTI executive • Distributed object management • Distributed object services • CORBA-based • C++, ADA, JAVA interfaces

  8. RTI Service Functionality Create and delete federation executions Federation Management Join and resign federation executions Control checkpoint, pause, resume, restart Establish intent to publish and subscribe to object attributes and interactions Declaration Management Create and delete object instances Object Management Control attribute and interaction publication Create and delete object reflections Ownership Management Transfer ownership of object attributes Coordinate the advance of logical time and its relationship to real time Time Management Data Distribution Management Supports efficient routing of data Implementation (2)

  9. Implementation (3) • Communications Services • Primitives • Create, destroy a group • Join, leave a group • Send a message to a group • Transport Mechanisms • Unicast (point-to-point) • Broadcast • Multicast

  10. Operations Startup Shutdown Ownership Management Time Management Data Distribution Management Object Management Declaration Management Federation Management Time Implementation (4)
