摘要

The DoD is pursuing an end-to-end, seamless, network-centric enterprise communications infrastructure to support a wide range of operating conditions and network topologies. Evaluating the achievable performance of this communications infrastructure, as it evolves, is essential to the user community in order to guide their ongoing requirements, design, and procurement activities. Tactical edge applications present significant challenges to network evaluation methods since they often include mobile ad-hoc networks (MANETs) that employ a wide range of platform types (ground-based, air-based, and satellite-based), traffic types (data, voice, video, and multimedia), delivery methods (unicast and multicast), offered traffic loads (kilobits/sec through megabits/sec), and numbers of nodes (from 10s to 1000s). The complexity exhibited by tactical edge applications typically demands the use of Modeling and Simulation (M&S) techniques, supported by high-fidelity models, to adequately quantify achievable performance on an end-to-end basis. However, these high-fidelity models often have very long runtimes, and restrictive limitations on scenario sizing. We investigate the application of the DoD High Level Architecture (HLA) and High Performance Computing (HPC) platforms to address the performance demands associated with analyzing tactical edge applications. A federation comprised of two Soldier Radio Waveform (SRW) federates and one Wireless Network after Next (WNaN) federate is developed and executed within an HPC environment at Aberdeen Proving Grounds (APG). High- fidelity OPNET models are used to represent the SRW and WNaN waveforms. Situational Awareness (SA) multicast traffic is delivered among the nodes represented within each of the three federates. Unicast traffic is exchanged between the SRW federates, in the presence of this SA background traffic, using the WNa.
