Fibre Channel Avionics Environment (FC-AE) is a group of protocols and profiles that specify Fibre Channel options for devices connected by fabric and/or loop topologies that are pertinent to their use in commercial and military aerospace industries. The primary areas of interest include avionic command, control, instrumentation, simulation, signal processing and sensor/video data distribution. These application areas are characterized by a variety of requirements, among them a need for high reliability, fault tolerance, and deterministic behavior to support real-time control/response. This part of ISO/IEC 14165 is intended to support bi-directional communication between two N_Ports in a constrained and carefully defined environment, typical of avionics applications. The primary objective of this part of ISO/IEC 14165 is to maximize the likelihood of interoperability between conforming implementations. This technical report Prohibits or Requires features that are optional and Prohibits the use of some non-optional features in the referenced standards. A second objective of this technical report is to simplify implementations and their associated documentation, testing, and support requirements. It does not define internal characteristics of conformant implementations, and it incorporates features from the referenced standards.
