Testing Runtime Infrastructure/Network Interactions for Latency

摘要

The Joint Advanced Distributed Simulation (JADS) Joint Test Force (JTF) is chartered by Office of the Secretary of Defense to investigate the utility of Advanced Distributed Simulation (ADS) Technology to Test and Evaluation (T&E). JADS is executing three test programs (C4I, Precision Guided Munitions and Electronic Warfare) representing slices of the overall T&E spectrum as well as observing other activity within the T&E community to form its conclusions. One of the slices, the Electronic Warfare test, is using HLA. To understand expected latency prior to the test execution, JADS is building a testbench to integrate and test the hardware and principle software components. This paper discusses the JADS plan to test the wide area network system latency prior to building the network and hosting the self-protection jammer (SPJ) test federation. The primary focus of this paper is on the process and tools used by JADS to characterize the RTI/network interactions, the system characterization measurements made in the testbed, and how that characterization will be fed back into the federation design.
