New Capabilities To Be
Demonstrated
• Rapid Validation of Comm Plans
– Evaluate effect of insertion of new technology (e.g.,
substitute new or COTS products for a portion of the
network)
• Rapid adaptive reconfiguration in response to
unexpected events
– Resource provisioning
– Throttling of certain applications
• Rapid analysis of network capabilities
– Network analysis for sensor-to-shooter scenario of
interest
New Technology Demonstrated
• Heterogeneous simulation capability
(combine models from different network
simulation packages)
• Distributed simulation capability over a
Run-Time Interface (RTI)
• Fast simulation capability, including use of
flow models where appropriate
• Real-Time measurement capability
NMS Integration Demo 01
• Target implementation of simulator in JICF
test facility, integrated with SSC SD
network testbed
– e.g., QualNet and NS tied together over a LAN
Backplane
• Integrate work of other PIs
– Flow models: Towsley
– Measurement: Claffy
Short Term Plans
• SPAWAR Systems Center SD:
– Collect & sanitize traffic traces from realistic Navy
scenarios such as in the Joint Interoperable
Communications Facility
– Express traffic as a SDF (Simulation Description File)
file
– Provide model description information to
UCLA/Georgia tech
• UCLA/Georgia Tech:
– Develop interfaces from SDF to the heterogeneous
simulation capability
– Develop relevant models with scalability
• All
– Simulate & validate traffic scenario
– Demo potential for scaling-up to evaluate large scale
battlefield exercises
