Abstract:

The Joint Advanced Distributed Simulation JADS Joint Test Force JTF is chartered by the Office of the Secretary of Defense to investigate the utility of Advanced Distributed Simulation ADS Technology to Test and Evaluation TE. JADS is executing three formal test programs representing slices of the overall TE spectrum to form its conclusions, linking live test assets, constructive models, and virtual simulations at multiple test facilities and test ranges across the country. Although each test targets different distributed equipment, all three tests have similar requirements for a methodology and tools that support evaluation of cross-country network performance and its impact on data quality. JADS uses a suite of both on-site and remote network monitoring tools to provide insight into distributed network performance before, during, and after test exercises. Prior to conducting any test exercise, it is important that a baseline analysis of the networks capabilities be performed. The comparison of baseline capabilities to projected network requirements allows identification of network shortcomings so that they can be addressed and provides confidence that distributed equipment will be able to communicate satisfactorily during testing. The baseline characterization of JADS network links includes Bit Error Rate Testing, or BERT, both no-load and loaded link latency testing, PDU or HLA packet verification testing, and stress testing. During JADS test execution, network analysis is an integral part of the test control and monitoring process. Latency, error rates, and data verification continue to be of high interest. In addition, packet rate, bandwidth utilization, link availability, and time synchronization across sites may be monitored real-time. A specific network portion may be monitored continuously if immediate notification of a network outage is necessary.
