This paper presents preliminary results of on-going work to evolve a networking architecture and a set of standards to support the development of interoperable simulators and simulations used to maintain Naval Aviation readiness through the Inter-Deployment Training Cycle (IDTC). The goal is to build an advanced networking infrastructure for simulator-based training systems used to meet operational training needs of aircrew at the Fleet Replacement Squadrons (FRS) and post-FRS squadrons, and eventually larger-scale, joint intra- and inter-service training objectives. The architecture and standards development are to be manifest in the Naval Aviation Simulation Master Plan, or NASMP. The challenges associated with NASMP development are significant and the effort is further complicated by an aggressive development schedule. Development of the NASMP networking architecture includes deriving objective training requirements, characterization of scenario (network) workloads, technology assessments, training device requirements, and identification of network deployment issues such as system engineering, integration, operational use, and support. The focus of this paper is on the definition of the NASMP network architecture, networking standards development, and network component interoperability issues. Other issues as they relate to networking and system interoperability are mentioned such as visualization and imaging, databases, and tactical environments. This paper presents a useful case study for persons interested in the development of a network architecture and the standardization of enabling technologies used to inter-connect simulator and simulation components in distributed, virtual training environments.
