Background - The use of Internet Protocol (IP) networking to acquire, manage and analyze data for test and evaluation is growing in popularity. In the past, IP hardware was a bad choice for data acquisition systems. However, with the advent of better technologies and the popularity of the Internet, IP networking is coming into favor in the test and evaluation community. A network-based approach provides the flexibility and scalability that previous acquisition systems could not support.
After discussions with domain and modeling experts, it was determined that the best way to capture the information relevant to network-based test and evaluation environment was to use a tool interchange format (TIF) known as the integrated network enhanced telemetry (iNET) metadata definition language (MDL). The MDL is a government effort that envisions one standard interchange format. Many vendors are in the process of transitioning to use this emerging standard format.
Approach - Our objective in this project was to construct a method of modeling and testing these network-based data acquisition systems and develop a demonstration prototype. We had three main tasks during this project:
