      The growth of the Internet and the resulting increasing speeds and decreasing prices of network equipment have spurred much interest in applying networks to flight test applications. However, the best-effort, variable-latency nature of network transport causes challenges that must be addressed to provide reliable data acquisition and timing performance. This paper describes the major issues that must be addressed when designing and implementing real-time networking applications. An overview of a recently implemented large-scale, network-centric data acquisition, recording, and telemetry system for commercial flight test applications provides a real-world example of what is currently achievable.
    • VEHICLE NETWORK TECHNOLOGY DEMONSTRATION

      iNET is a project tasked to foster advances in networking and telemetry technology to meet emerging needs. This paper describes one objective of the project, which is standardization and interoperability. It begins to explore issues for achieving a level of interoperability among differing vendor’s hardware such as data acquisition units, data recorders, video systems, transceivers, and network encryption. Specifically, this paper addresses the expansion of the current demonstration system with the addition of multiple vendor data acquisition units. It will also attempt to address the level of standardization necessary for achieving interoperability while still enabling vendors to add their value added contributions into their products.
