      Bertrand, Allison R.; Grace, Thomas B.; Abbott, Ben A.; Saylor, Kase J.; Southwest Research Institute; Naval Air Systems Command (NAVAIR) (International Foundation for Telemetering, 2008-10)
      The Integrated Network Enhanced Telemetry (iNET) Project established a standards working group to address the integrated management of telemetry network systems and to ensure interoperability among various pieces of equipment. The group has been studying the benefits and drawbacks of various system management technologies with the goal of identifying a set of management interfaces which will provide long-range benefit to a large and diverse telemetry test system. This paper discusses control, configuration, status, performance, and fault management. It addresses these from several viewpoints such as multi-test articles, multi-ranges, and dynamic test environments.
    • Technology Trades in IP-Based Telemetry Networks

      Kenney, Joshua D.; Moodie, Myron L.; Ragsdale, Gary L.; Grace, Thomas B.; Southwest Research Institute; Naval Air Systems Command (NAVAIR) (International Foundation for Telemetering, 2008-10)
      The integrated Network Enhanced Telemetry (iNET) project established a test article standards working group to define open standards for network components and interfaces for test articles in the aeronautical test environment. Its aim is to utilize the growth of Internet technologies for telemetry networks and ensure interoperability among network devices. This paper describes the technology background and the current technology trades of an IP-based network paradigm used in producing standards for test article networks. Specifically, the paper will include descriptions of selected network technologies as applied to test data and time distribution within test articles.
    • TENA in a Telemetry Network System

      Saylor, Kase J.; Malatesta, William A.; Abbott, Ben A.; Southwest Research Institute; Naval Air Systems Command (NAVAIR) (International Foundation for Telemetering, 2008-10)
      The integrated Network Enhanced Telemetry (iNET) and Test and Training Enabling Architecture (TENA) projects are working to understand how TENA will perform in a Telemetry Network System. This paper discusses a demonstration prototype that is being used to investigate the use of TENA across a constrained test environment simulating iNET capabilities. Some of the key elements being evaluated are throughput, latency, memory utilization, memory footprint, and bandwidth. The results of these evaluations will be presented. Additionally, the paper briefly discusses modeling and metadata requirements for TENA and iNET.
    • XML Data Modeling for Network-Based Telemetry Systems

      Price, Jeremy C.; Moore, Michael S.; Malatesta, Bill A.; Southwest Research Institute; Naval Air Systems Command (NAVAIR) (International Foundation for Telemetering, 2008-10)
      Network-based telemetry systems are often made up of many components from multiple vendors. The complexity involved in coordinating the design, integration, configuration, and operation of these systems has required instrumentation engineers to become experts in the tools and hardware from various vendors. Interoperation between the various tools and systems is very limited. One approach toward a more efficient method of managing these systems is to define a common language for describing the goals of the test, the measurements to be acquired, and the equipment that is available to compose a system. Through an open working group process, the iNET program is defining an eXtensible Markup Language (XML)-based language for describing instrumentation and telemetry systems. The language is designed with multiple aspects that allow filtered views into the instrumentation system, making the creation of the various parts of the documents more straight-forward and understandable to the type of user providing the information. This paper will describe the iNET metadata project, the model-driven approach that is being pursued, and the current state of the iNET metadata language.
