Switched for Networked FTI

ITC/USA 2010 Conference Proceedings / The Forty-Sixth Annual International Telemetering Conference and Technical Exhibition / October 25-28, 2010 / Town and Country Resort & Convention Center, San Diego, CaliforniaEthernet technology offers numerous benefits for networked Flight Test Instrumentation (FTI) systems such as increased data rates, flexibility, scalability and most importantly interoperability owing to the inherent interface, protocol and technological standardization. In a networked FTI system, the switch is a key component that allows data to be routed between Data Acquisition Units (DAU's), networked recorders, data processing and analysis stations. This paper provides an introduction to network switching concepts with a focus on its operation in a networked FTI system. The features of Commercial Off-The-Shelf (COTS) and FTI switches are compared demonstrating the benefits of FTI switches in terms of reliability, routing, throughput, latency, and start-up delays.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
