It is critical for the ARMY to have robust capability to test and evaluate the operational capabilities of the newly-developed mission command systems in a realistic tactical communication environment. Performance of the modern tactical transport networks of radios heavily depends on the scale of the network amongst other factors. This presents challenges to procuring enough radio assets for testing activities, especially if the radio waveform is early in its development cycle. To address this, many network emulators have been developed and are capable of producing the real-time communications effect of the transport network. The common approach taken is to “instantiate” the transport network either by developing simulation models in the emulator or by porting the actual waveform code into the emulator. This significantly increases the cost and time, both in developing the emulator and in running the tests. For example, behavior change in the waveform or adding a new waveform into the emulator becomes a costly and time consuming M&S development activity requiring verification and validation (V&V). In this paper we describe a new transport network emulator: the Communications Effect Server PLUS (CES+). In CES+, instead of instantiating waveforms, the end-to-end waveform behavior in terms of its packet loss, latency and their distribution are stored in a database as a function of the network loading and other networking conditions. The database obtains values from either field/lab data or from high-fidelity simulation models that have in turn been calibrated against field and lab test data. As such, waveform update becomes an activity of database update with new measurements, not an M&S model development activity. Novel principles described in this paper are utilized in CES+ to approximate the tactical transport networks performance at scale with most accuracy To date, CES+ has been extensively used by the Army in various design and dev- lopmental test activities, including evaluation of the network integration readiness levels (NIRLs) and integrated performance of the digital Fires systems. |
