A proposed local area network for next-generation avionic systems

The Fiber-optic Data Distribution Network (FDDN) is described that has been proposed to meet the data communication demands for advanced aircraft avionics. Performance, fault-tolerance, and versatility are primary objectives of the FDDN approach. The ultimate goal is to offer aircraft designers a powerful interprocessor communications capability for next-generation avionic platforms. A brief examination of the data communication requirements for distributed, real-time avionic systems is presented, followed by the rationale for selection of a network. The functional description of the FDDN is provided, and the development status is summarized.<
