Abstract:
System for providing non-flight critical aircraft sub-system communication, over an ALAN, meeting DO-254/DO-178 certification. This system deterministically makes data available to each aircraft sub-system without regard to specific bandwidth requirements. This system network supports functions that are certified on a non-interference basis. The system network deterministically places all non-required functionality into a low priority to assure that all required data functions sets are not dropped. One aspect of this system is how the clients are able to join sessions. In this system, network clients are preprogrammed based on their hardware coding to be able to join a specific LVAN, or LVANs, in accordance with their predetermined functions. The present system is an ALAN based on a ring Ethernet topology, for redundancy, which provides two paths to each connection point without requiring all the wiring associated with a star wiring topology.
