ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / Current real-time data communications links supporting Major Range and Test Facility Base (MRTFB) operations are one-way, dedicated links based on the IRIG 106 standard. One of the goals of the iNET program is to provide for shared, two-way networked communications links enabling more flexible operation and more efficient use of spectrum. Central to this goal is the provision for a Spectrum Assignment Manager (SAM) as referred to in the iNET architecture. The SAM element of the Resource Management Facility (RMF) works in concert with the TmNS Network Manager to support dynamic frequency assignment and real-time metrics adjustment. This paper describes the potential role, key functions, and technology elements needed to support this important function.
