Introduction
The High Level Architecture (HLA) is a distributed simulation architecture specification
A Run Time Infrastructure (RTI) is an implementation of this specification
A mix of a peer to peer and a centralized distribution
Objects are persistant and “updated”
Interactions are events and are “sent”

4. Project Goal
This project will create a virtual environment that will immerse the system designer in the distributed simulation infrastructure not the virtual environment that is created by the participating simulations.
This view will allow the system designers to experience the data flows between the federates and look for problems and performance bottlenecks.
Reduce problem isolation time
Increased insight into federation performance

5. Design Principles Consolidate distributed information
Keep it simple (7 ± 2 chunks of information)
Allow drill down to details
Visualize relative magnitudes
3D aural cues
Sensitive to tonal and rhythmic changes
Auditory localization for detecting changes in the infrastructure component performance

6. System Description
The system will join the federation as a federate to collect
Management Object (MOM) data about the federates
Data specific to this project sent from the federates
The system will display this information in a manner to facilitate the goal of the project.

7. Test Environment Data Flows

8. Current Vision “Floor” of 2D network map
Federates floating but anchored to the physical location on the floor
Visual bars on federates for cumulative data
Aural queues for time advance requests and grants
Federates can be entered or examined for detailed information

9. Current Vision Example

10. VE Application Software
Xith3d which is based on Java Open GL (JOGL) and Java Open AL (JOAL) for 3D visual and aural displays
RTI NG-Pro V2.0.2 implementation of the High Level Architecture v1.3
Will join the HLA federation
Use specific interactions for this project and generic MOM data
