Abstract
An aircraft communication system includes primary and secondary networks. The system also includes an interconnection gateway with a filtered interface connected to only one of the primary and secondary networks, and an unfiltered interface connected to the other network. The filtered interface includes first incoming and outgoing buffers, a memory, and a selector. The unfiltered interface includes second incoming and outgoing buffers. The second incoming buffer sends all frames received from the other network to the first outgoing buffer for distribution through the only one network. The selector selects common data frames corresponding to virtual link identifiers in a stored list and copies only the selected common data frames from the first incoming buffer to the second outgoing buffer of the unfiltered interface for distribution through the other one of the networks.
