Significant MS Exercises Using RTI 1.3NGvx
- AMC RDEC Federation
- SMART 2001
- Calibration Exercise
- Future Combat Command Control Experiment (FCC2)
- Joint Virtual Battlespace

Paint the Night Federate Applications

RTI Implementation Issues Encountered
- RID File Parameters
- Advisories
- Reliable Versus Best Effort Delivery
- Discovery Process Could Take 5 minutes
- Significant Impact on Operations
- Queue Management
- With Advisories, Queuing Problems Observable
w/700 objects - Need a Fast Track for Priority Data (e.g.
control information) - Interest Management
- Updating ROIs Required As Much As A Minute
- PST Federation Worked Around DDM Problems By
Adopting a Gateway Filter
6
RTI Implementation Issues Encountered (Cont.)
- RTI Deployment And Support
- PTN Sensor Effects Federate - Sole Windows NT
Application, Uses VC6 Compiler - Integration of TARDEC VTT Simulator Also
Impacted By Lack of GCC Support - 32 Bit System Memory Management Is Limiting
- Benchmarking and Diagnostic Tools
- DDM Diagnostics Are A Must
- Benchmarking Tools Should Account for Object
Updates As Well As Total Number of Objects - Isolation of Latency Source(s) Is a Key
Consideration - Better Tools Could Reduce the Time Required To
Conduct Integration and Testing
7
Recommended Improvements
- Declaration Management and Queuing
- Should Be Able to Flush RTI Queue
- Priority Queuing Should Be Supported
- Declaration Management Should Allow For
Discoveries In the Background Federates Should
be Able to Join Federation Immediately, Rather
than Wait for Discovery to Complete - Data Distribution Management
- DDM Best Practices and Pitfalls Should Be
Documented - RID File Upgrades
- Add Rid File Parameter to Control Which Interface
To Use for Reliable Traffic - Support for Multiple rtiexec, Multiple Subnets
8
Recommended Improvements (cont.)
- Establish Hard Boundary on Maximum Tick to
Improve Polling - Should Be Able to Query How Many Callbacks are
In Queue - Remove Concurrent Access Restrictions from All
Callbacks - (If Not Already Done)
- Cross_Platform Support
- Support CYGWIN, with GCC Support for Win32
- Consider 64 Bit Implementation or Ability to
Remap in Memory - (Important for graphics intensive
applications) - Benchmarking And Diagnostic Tools
- Expand Functionality of Existing DMSO Tools to
Support - Multiple RID File Options
- Test Conditions
- Data Analysis
- Should Be Able to Visualize Profile of Where
Data Is Sent
9
Issues and Conclusions
- Continued Support for Windows NT and IRIX OS
- Compatibility of Commercially Available RTIs
- Composability Versus Ease of Application Level
Development - FOM Agility
- OMD2Code Approach
- Gateways and Bridge Federates
- Scalability
Recommended
